AB  - This paper describes a promising electrophoretic deposition (EPD) approach for developing composite coatings based on chitosan with the additional components of hydroxyapatite, graphene, and gentamicin on titanium substrate. Bioactive properties were investigated in vitro by immersing the coatings in simulated body fluid (SBF) at 37 degrees C. The newly formed biomimetic layer on the top of the deposited chitosan-based coatings on Ti was confirmed by X-ray diffraction, Fourier transform infrared spectroscopy, field emission scanning electron microscopy and electrochemical measurements, while coatings' bioactivity was proved by alkaline phosphatase activity assay in MRC-5 and L929 tested cell lines. The biocompatibility towards MRC-5 and L929 cell lines was investigated by dye exclusion test (DET) implying the non-cytotoxic effect of coatings. Gentamicin release studies were monitored during 21-day by high-performance liquid chromatography coupled with mass spectrometry, indicating rapid release of gentamicin (approximate to 40%) in the first 48 h and more than 60% after 14 days.

AB  - Polymer-based hydrogel materials are excellent candidates for new-generation wound dressings with improved properties, such as high sorption ability, good mechanical properties and low adhesiveness. Cross-linked hydrogel matrices also serve as excellent carriers for controlled release of antibacterial agents, such as silver nanoparticles (AgNPs), which are preferred over conventional antibiotics due to low propensity to induce bacterial resistance. In this work, we aim to produce novel silver/poly(vinyl alcohol)/chitosan (Ag/PVA/CHI) hydrogels for wound dressing applications. The electrochemical AgNPs synthesis provided facile and green method for the reduction of Ag+ ions inside the hydrogel matrices, without the need to use toxic chemical reducing agents. The formation of AgNPs was confirmed using UV-visible spectroscopy, scanning and transmission electron microscopy. Release kinetics was investigated in modified phosphate buffer solution at 37 degrees C to mimic physiological conditions. Release profiles indicated "burst release" behavior, which is beneficial for wound dressing applications. The antibacterial activity was evaluated against Staphylococcus aureus and Escherichia coli strains using disc-diffusion test, and non-toxicity of hydrogels was proved by dye-exclusion test. The obtained results confirmed strong potential of Ag/PVA/CHI hydrogels for biomedical applications.

AB  - The electrophoretic deposition process (EPD) was utilized to produce bioactive hydroxyapatite/chitosan (HAP/CS) and hydroxyapatite/chitosan/gentamicin (HAP/CS/Gent) coatings on titanium. The bioactivity of newly synthesized composite coatings was investigated in the simulated body fluid (SBF) and examined by X-ray diffraction, Fourier transform infrared spectroscopy, and field emission scanning electron microscopy. The obtained results revealed carbonate-substituted hydroxyapatite after immersion in SBF, emphasizing the similarity of the biomimetically grown HAP with the naturally occurring apatite in the bone. The formation of biomimetic HAP was confirmed by electrochemical impedance spectroscopy and polarization measurements, through the decrease in corrosion current density and coating capacitance values after 28-day immersion in SBF. The osseointegration ability was further validated by measuring the alkaline phosphatase activity (ALP) indicating the favorable osseopromotive properties of deposited coatings (significant increase in ALP levels for both HAP/CS (3.206 U mL(-1)) and HAP/CS/Gent (4.039 U mL(-1)) coatings, compared to the control (0.900 U mL(-1))). Drug-release kinetics was investigated in deionized water at 37 degrees C by high-performance liquid chromatography coupled with mass spectrometry. Release profiles revealed the beneficial "burst-release effect" (similar to 21% of gentamicin released in the first 48 h) as a potentially promising solution against the biofilm formation in the initial period. When tested against human and mice fibroblast cells (MRC-5 and L929), both composite coatings showed a noncytotoxic effect (viability  gt 85%), providing a promising basis for further medical application trials.

AB  - This study reports in-situ cesium-doped graphene (G/Cs) coating obtained by introducing Cs2CO3 into the atmospheric pressure chemical vapor deposition (APCVD) furnace during graphene deposition on copper. The successful Cs-doping of the graphene coating was confirmed via X-ray photoelectron spectroscopy (XPS). As compared to the spectra of pure graphene coating, the XPS spectra of the G/Cs coating revealed a shift of the C1s and Cs3d(5/2) peaks to higher and lower binding energies, respectively; thus, implying the n-type character of the doping and indicating a charge transfer between Cs and graphene. Raman results show that a pure graphene coating is composed of fewer layers, fewer defects, and larger domain size than the G/Cs coating. Ultraviolet photoelectron spectroscopy was utilized to study the work function of graphene and the G/Cs and revealed that doping graphene with Cs dopants reduced the work function of graphene by 1.2 eV. Electrochemical testing during 15-day immersion in 0.1 M NaCl indicated the destructive effect of the G/Cs coating on the Cu substrate. The results showed that the G/Cs coating exhibits a higher corrosion rate and lower corrosion resistance than even the bare metal itself.

AB  - Silver nanoparticles (AgNPs) were synthesized by in situ electrochemical reduction of Ag+ ions in poly (vinyl alcohol)/chitosan/graphene (PVA/CHI/Gr) hydrogel matrices with different concentrations of chitosan. The physicochemical properties of nanocomposite hydrogels were investigated by UV-vis spectroscopy (UV-vis), dynamic light scattering (DLS), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), field-emission scanning electron microscopy (FE-SEM) and Fourier transform infrared spectroscopy (FT-IR), thermal characteristics were determined by differential scanning calorimetry (DSC) and mechanical properties were measured by tensile test. The swelling studies were carried out in phosphate buffer to simulate natural physiological environment and data were fitted by several kinetic models to determine the diffusion mechanism and diffusion coefficients of the swelling medium through the hydrogel matrices. It was shown that the presence of silver nanoparticles increased the uptake capability and equilibrium swelling degree of the composite hydrogels. The antibacterial activity was confirmed against Escherichia coli and Staphylococcus aureus, while the hydrogels without AgNPs exhibited antibacterial properties due to the presence of chitosan. With the addition of AgNPs, the samples showed stronger activity and fast reduction in the number of colonies, confirming the synergistic effect of chitosan and AgNPs on the antibacterial activity.

With the addition of AgNPs, the samples showed stronger activity and fast reduction in the number of colonies, confirming the synergistic effect of chitosan and AgNPs on the antibacterial activity.",

AB  - In this work, we provide a facile path for the preparation of wound dressing materials with improved characteristics based on biocompatible chitosan and poly(vinyl alcohol) hydrogels with embedded silver nanoparticles (AgNPs) as a potent antimicrobial agent. The hydrogels were prepared via freezing-thawing method, whereas AgNPs were synthesized via an in situ electrochemical route. The excellent physicochemical properties of the obtained nanocomposite hydrogels were validated using different spectroscopic and microscopic techniques. The formation of sub-10 nm AgNPs was confirmed by UV-visible spectroscopy, dynamic light scattering and transmission electron microscopy. Swelling and silver release profiles were validated using several diffusion models. The hydrogels were proven to be non-cytotoxic using MTT test and possessed powerful antibacterial activity against Staphylococcus aureus and Escherichia coli, as determined by test in suspension, which affirmed their feasibility for wound dressing applications.

AB  - In this work an attempt was made to produce epoxy coating doped with ceria (CeO2) and/or zirconia (ZrO2) nanoparticles, in single step electrophoretric deposition process. Deposition was carried out on AA6060 cataforetically from epoxy resin suspension containing synthesized stable aqueous colloidal dispersions (sols) of CeO2 and ZrO2. The influence of ceria and zirconia nanoparticles on the physicochemical characteristics of epoxy coatings was evaluated by energy dispersive X-ray fluorescence spectroscopy, X-ray photoelectron spectroscopy, field-emission scanning electron microscopy, Fourier-transform infrared spectroscopy, thermogravimetric analysis and adhesion measurements, while their corrosion stability during immersion in 0.5 M NaCl solution was monitored by electrochemical impedance spectroscopy. All ceria and/or zirconia containing coatings showed better corrosion stability and adhesion than pure epoxy coating, while between doped epoxy coatings one with CeO2/ZrO2 exhhibited the greatest values of charge-transfer resistance due to synergetic effect of both types of added nanoparticles.

AB  - Increasing need for improved, compatible bone tissue implants led to the intensive research of novel biomaterials, especially hydroxyapatite (HAP)-based composite materials on titanium and titanium alloy surfaces. Owing to its excellent biocompatibility and osteoinductivity properties, hydroxyapatite is often used as part of composite biomaterials aimed for orthopedic implant applications. In order to overcome persistent problems of bacterial infection, various antimicrobial agents and materials and their incorporation in such medical devices were investigated. This paper represents a comprehensive review of single-step electrodeposition on titanium of hydroxyapatite/chitosan/graphene composite coatings loaded with silver and antibiotic gentamicin as antibacterial agents. The improvement of mechanical and adhesive properties of deposited composite coatings was achieved by graphene and chitosan addition, while desirable antibacterial properties were introduced by including antibiotic gentamicin and silver. The biocompatibility of electrodeposited HAP and HAP-based composite coatings was evaluated by MTT testing, indicating a non-cytotoxic effect and high potential for future medical use as orthopedic implant coating.

AB  - In this study, the corrosion behaviour of carbon nanotubes (CNTs) coated basalt fibre (BF) (BFCNTs) obtained by chemical vapour deposition (CVD), was studied. During CVD, the CNTs were grown on BF, (a) at different growth temperatures and (b) for different growth times. The physicochemical measurements were performed using X-ray diffraction, Raman spectroscopy, and field-emission scanning electron microscopy. The corrosion performances were investigated using electrochemical impedance spectroscopy (EIS), potentiodynamic sweep (PDS), linear polarization resistance (LPR) and weight loss measurements. The BFCNT prepared at 650 degrees C for 120 min exhibited the best corrosion stability during the prolonged exposure to 0.1 M NaCl electrolyte. The outcomes of this study would be useful in designing the carbon nanotubes coated basalt fibre with the best corrosion resistance.

AB  - Composite coating of antibiotic gentamicin (Gent), natural polymer chitosan (CS), and hydroxyapatite (HAP) was successfully assessed by applying the electrophoretic deposition (EPD) technique. EPD was performed under optimized deposition conditions (5 V, 12 min) on pure titanium plates, to obtain HAP/CS and HAP/CS/Gent composite coatings in a single step from three-component aqueous suspension, with favorable antibacterial properties. Composite coatings were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, and X-ray photoelectron analysis, confirming the formation of composite HAP/CS and HAP/CS/Gent coatings on the titanium surface, which is due to intermolecular hydrogen bonds. Employing the XRD technique, HAP was detected by obtaining the characteristic diffraction maximums. Good antibacterial activity of the composite coating loaded with antibiotic (HAP/CS/Gent) was confirmed against Staphylococcus aureus and Escherichia coli, pointing to the high potential for bioapplication. Introduction of gentamicin in HAP/CS/Gent coating caused very mild cytotoxicity in the tested cell lines MRC-5 and L929. MTT testing was used to evaluate cell viability, and HAP/CS was classified as noncytotoxic.

AB  - This study presents the synthesis of novel silver/poly(vinyl alcohol)/chitosan/graphene (Ag/PVA/CHI/Gr) nanocomposite hydrogels by in situ electrochemical reduction of silver ions in the hydrogel matrix and their thorough characterization by UV-visible and Raman spectroscopies, field-emission scanning electron microscopy (FE-SEM), X-ray photoelectron spectroscopy (XPS), and silver release measurements. The influence of chitosan content on the incorporation and stabilization of silver nanoparticles (AgNPs) was investigated, and we found that hydrogels with higher chitosan content contain higher amounts of AgNPs. In addition, the cytotoxicity and antibacterial activity of Ag/PVA/CHI/Gr nanocomposite hydrogels were evaluated. Based on in vitro investigations, the obtained materials exhibit diffusion-controlled release profiles over 28 days, strong antibacterial activity against Staphylococcus aureus and Escherichia coli bacterial strains, and no cytotoxicity toward human and mice fibroblast cell lines.

AB  - In this work, we present the results of electrochemical, Raman, FE-SEM/EDS, and XPS studies of graphene coatings deposited by chemical vapour deposition at atmospheric pressure on Mo foil and Pt-coated Mo foil as catalysts. The results showed that the graphene coating synthesized on Pt-coated molybdenum foil was bi-layer and had fewer defects, while the graphene coating on Mo foil was few-layer with more defects. The corrosion studies indicated that both graphene coatings on bare Mo and Pt-coated Mo exhibited good protective properties and can act as a barrier against corrosion in 0.1 M NaCl.

AB  - This paper presents silver/poly(vinyl alcohol) (Ag/PVA) and silver/poly(vinyl alcohol)/graphene (Ag/PVA/Gr) composites prepared by the immobilization of silver nanoparticles (AgNPs) in PVA and PVA/Gr hydrogel discs previously cross linked by the freezing/thawing method. The AgNPs inside the hydrogel matrices were synthesized following an innovative in situ method of electrochemical reduction of Ag+ ions within PVA and PVA/Gr hydrogel discs. In addition, the novel materials introduced here were characterized by UV-visible spectroscopy, cyclic voltammetry, Raman spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, silver release measurements, and thermogravimetric analysis. The effective immobilization of the AgNPs inside the PVA and PVA/Gr hydrogel networks was achieved by their bonding with the exposed hydroxyl groups in PVA. Also, the incorporation of graphene into the PVA matrix and the bonding between PVA molecules and incorporated graphene sheets improves thermal stability of Ag/PVA/Gr and prevents aggregation and growth of AgNPs as observed by Fourier transform infrared spectroscopy and field emission scanning electron microscopy.

AB  - In this work, composite hydrogel consisting of poly(vinyl alcohol), graphene and silver nanoparticles, (Ag/PVA/Gr), was prepared by the immobilization of silver nanoparticles (AgNPs) in PVA/Gr hydrogel matrix in two steps. The first step was cross linking of the PVA/Gr colloid solution by the freezing/thawing method, while in the second step, in situ electrochemical method was used to incorporate AgNPs inside the PVA/Gr hydrogel matrix. We used UV-vis spectroscopy, cyclic voltammetry, Raman spectroscopy, DSC analysis, as well as test of cytotoxicity and antibacterial activity, to characterize obtained Ag/PVA/Gr hydrogel. It was shown that graphene- based composite hydrogel with incorporated AgNPs is non toxic biomaterial with antibacterial activity, with a potential for use in biomedical purposes.

AB  - In this paper, novel silver-doped poly(vinyl alcohol)/chitosan/graphene (Ag/PVA/CHI/Gr) nanocomposites were produced by in situ electrochemical synthesis of silver nanoparticles in the polyvinyl alcohol/chitosan/graphene (PVA/CHI/Gr) matrix. The presence of silver nanoparticles, as an antibacterial agent, was proven by ultraviolet-visible spectroscopy. The synthesized nanocomposites were further characterized by scanning electron microscopy, Raman spectroscopy, and x-ray photoelectron spectroscopy. Thermal stability was investigated using thermogravimetric analysis, while electrochemical properties of PVA/CHI/Gr and Ag/PVA/CHI/Gr were examined by cyclic voltammetry. It was suggested that silver nanoparticles were embedded in the PVA/CHI/Gr matrix as a result of chemical bonding with hydroxyl groups of PVA and amine and hydroxyl groups of CHI, and have improved thermal stability of PVA/CHI/Gr hydrogel.

AB  - Graphene (Gr) and natural polymer chitosan (CS) were introduced to hydroxyapatite (HAP) to produce a three-component composite coating, which was fabricated by cathodic electrophoretic deposition on Ti substrates in an ethanol suspension. These HAP/CS/Gr coatings were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS) and electrochemical measurements and found that the graphene into HAP/CS composites significantly improves their morphology, thermal stability, and bioactivity. Both HAP/CS and HAP/CS/Gr composite coatings are classified as non-cytotoxic when tested against healthy peripheral blood mononuclear cells (PBMC), while antibacterial activity against Staphylococcus aureus and Escherichia coil could not be verified.

AB  - This work focuses on the optimization of electrochemical synthesis of silver nanoparticles in poly(vinyl alcohol) colloid solutions, films and hydrogel discs with the ability for immobilization of silver nanoparticles and their progressive release, as a new, prospective generation of medical wound dressings. Incorporation of silver nanoparticles into polyvinyl alcohol and polyvinyl alcohol/graphene matrices, with the aim to determine the effect of silver and graphene, was achieved by the electrochemical synthesis at different values of constant current density between 10 and 40 mA cm(-2) and for different time between 10 and 75 min, followed by drying (to obtain films) or freezing-thawing method (to obtain hydrogels). Synthesized nanocomposites were characterized by UV-Visible spectroscopy (UV-Vis), transmission electron microscopy (TEM), cyclic voltammetry (CV), Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy and atomic absorption spectroscopy (AAS). Additionally, antibacterial activity of thus prepared samples was evaluated against pathogenic bacteria strains Staphylococcus aureus and Escherichia coli using agar diffusion test. The results indicated that both silver/polyvinyl alcohol and silver polyvinyl alcohol/graphene nanocomposites are excellent candidates for soft tissue implants and wound dressings.

Introduction of Gr led to improved mechanical and thermal properties of the PVA/Gr nanocomposite compared to pure PVA, as well as strong antibacterial activity against the bacterial strain Staphylococcus aureus. The PVA/Gr nanocomposite was non-cytotoxic against healthy peripheral blood mononuclear cells by MTT assay, indicating its high potential for biomedical applications.

AB  - Silver/poly(vinyl alcohol) and silver/poly(vinyl alcohol)/graphene nanocomposites in different forms (colloid dispersion, thin films and hydrogel discs) were synthesized by electrochemical reduction of Ag+ ions at constant current density. CV, Raman, XRD, FT-IR, and XPS analyses were used to characterize the interactions between silver nanoparticles, PVA molecules, and graphene. Ag/PVA/Gr nanocomposites had better mechanical and thermal properties and higher antibacterial activity against Staphylococcus aureus and Escherichia coli than Ag/PVA nanocomposites. Slow silver release, as well as a high remaining silver content (76%) after 28 days in simulated body fluid confirmed that both Ag/PVA and Ag/PVA/Gr nanocomposites are capable of maintaining sterility over time.

AB  - In this work, the effect of pre-annealing of Mo substrate on the quality of graphene layers grown by chemical vapour deposition was investigated by X-ray diffraction, X-ray photoelectron spectroscopy, and Raman spectroscopy. Moreover, different electrochemical techniques were employed to investigate the corrosion stability of the graphene coated Mo in 0.1 M NaCl. Longer annealing time resulted in less defective graphene coatings with fewer layers. Graphene coating on the annealed Mo provided better protection against corrosion during the initial exposure times, while after prolonged exposure times, both graphene coatings on annealed and non-annealed Mo exhibited nearly the same corrosion inhibitive properties.

AB  - The hydroxyapatite/graphene (HAP/Gr) composite was electrodeposited on Ti using the electrophoretic deposition process to obtain uniform bioactive coating with improved mechanical strength and favorable corrosion stability in simulated body fluid (SBF). Incorporation of Gr was verified by Raman spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, thermogravimetric analysis, and X-ray photoelectron analysis. The HAP/Gr composite coating exhibited reduced surface cracks, nearly double the hardness, and elastic modulus increased by almost 50% compared to pure HAP coating, as estimated by a nanoindentation test. The bioactive HAP/Gr composite coating provided a newly formed apatite layer in SBF with enhanced corrosion stability, as evidenced by electrochemical impedance spectroscopy. The thermal stability of the HAP/Gr coating was improved in comparison to the pure HAP coating, and the Ca/P ratio was closer to the stoichiometric value. No antibacterial activity against Staphylococcus aureus or Escherichia coli could be verified. The HAP/Gr composite coating was classified as non-cytotoxic when tested against healthy peripheral blood mononuclear cells (PBMC).

AB  - Electrochemical synthesis was employed to prepare a novel hydroxyapatite/graphene (HAP/Gr) composite powder suitable for medical applications as a hard tissue implant (scaffold). The synthesis was performed in a homogeneous dispersion containing Na(2)H(2)EDTA center dot 2H(2)O, NaH2PO4 and CaCl2 with a Ca/EDTA/PO43- concentration ratio of 0.25/0.25/0.15M, along with 0.01 wt% added graphene nanosheets, at a current density of 137 mA cm(-2) and pH value of 9.0. The field emission scanning electron microscopy and transmission electron microscopy observations of the composite HAP/Gr powder indicated that nanosized hydroxyapatite particles were uniformly placed in the graphene overlay. Raman spectroscopy, Fourier transform infrared spectroscopy and X-ray diffraction confirmed graphene incorporation in the HAP/Gr powder. The electrochemically prepared HAP/Gr composite powder exhibited slight antibacterial effect against the growth of the bacterial strain Staphylococcus aureus.
