AB  - The syntheses of Ag-based nanoparticles (NPs) with the assistance of plant extracts have been shown to be environmentally benign and cost-effective alternatives to conventional chemical syntheses. This study discusses the application of Paliurus spina-christi, Juglans regia, Humulus lupulus, and Sambucus nigra leaf extracts for in situ synthesis of Ag-based NPs on cotton fabric modified with citric acid. The presence of NPs with an average size ranging from 57 to 99 nm on the fiber surface was confirmed by FESEM. XPS analysis indicated that metallic (Ag0) and/or ionic silver (Ag2O and AgO) appeared on the surface of the modified cotton. The chemical composition, size, shape, and amounts of synthesized NPs were strongly dependent on the applied plant extract. All fabricated nanocomposites exhibited excellent antifungal activity against yeast Candida albicans. Antibacterial activity was significantly stronger against Gram-positive bacteria Staphylococcus aureus than Gram-negative bacteria Escherichia coli. In addition, 99% of silver was retained on the samples after 24 h of contact with physiological saline solution, implying a high stability of nanoparticles. Cytotoxic activity towards HaCaT and MRC5 cells was only observed for the sample synthetized in the presence of H. lupulus extract. Excellent antimicrobial activity and non-cytotoxicity make the developed composites efficient candidates for medicinal applications.

Synthetized spherical nanoparticles with an average diameter of 60 nm were evenly

provided excellent antimicrobial activity against bacteria Staphylococcus aureus and

AB  - The demand for medical textiles in various forms with strong antimicrobial activity drastically increased during the COVID19 pandemic. In an attempt to tackle this issue and to develop antimicrobial textiles in more environmentally benign manner, a viscose fabric after coating with biopolymer chitosan has been impregnated with Ag- and Cu-based nanoparticles. Chitosan was applied in the presence and absence of cross-linker 1,2,3,4-butanetetracarboxylic acid (BTCA). In situ green synthesis of nanoparticles was performed using a Punica granatum (pomegranate) peel extract as a reducing and stabilizing agent. Formation of nanoparticles on the fiber surface was confirmed by FESEM. Elemental analysis by XPS showed the synthesized nanoparticles exist as AgCl and a mixture of Cu/CuO/Cu2O in the modified samples. Moreover, these nanoparticles appeared to be present not only on the sample surface but also buried within the fibers, as indicated by XPS mapping and depth profiling measurements. All impregnated fabrics exhibited excellent antifungal activity providing the maximum reduction of yeast Candida albicans colonies. Antibacterial activity was stronger against Gram-negative bacteria Escherichia coli than Gram-positive bacteria Staphylococcus aureus, and it was highly influenced by metal content. The fabrics impregnated with AgCl nanoparticles showed lower cytotoxicity towards human keratinocyte cells.

AB  - The aim of this study was to develop antimicrobial nanocomposite textile material comprising of Cu-based nanostructures synthesized on oxidized cotton fabric using Arctostaphylos uva-ursi (L.) Spreng., Ericaceae (bearberry leaves) as a green reducing agent for adsorbed Cu2+-ions. In order to provide sufficient number of carboxyl groups for complexation with Cu2+-ions a two-step oxidation process with NaIO4 and NaClO2 was carried out. The influence of NaIO4 concentration on content of carboxyl groups and Cu-based nanoparticles was studied by FTIR and AAS. HPLC analysis identified the gallic acid known as a reducing agent in bearberry leaves extract. FESEM and XRD analyses revealed that using bearberry leaves extract and gallic acid solution as reducing agents led to a formation of spherical Cu2O/CuO nanoparticles and CuO nanosheets, respectively. These nanoparticles and nanosheets provided excellent antibacterial activity against Gram-negative bacteria Escherichia coli and Gram-positive bacteria Staphylococcus aureus. Cytotoxicity on human keratinocyte cells was shown to depend on their copper content.

AB  - U ovom radu diskutovana je mogućnost sinteze nanolistića na bazi Cu na pamučnoj tkanini koji bi
pružili željeni nivo antimikrobne aktivnosti. Da bi se obezbedio dovoljan broj karboksilnih grupa za
vezivanje Cu2+
-jona iz rastvora soli prekursora pamučna tkanina je selektivno oksidisana u
dvostepenom procesu sa NaIO4 i NaClO2. Sorbovani Cu2+
-joni su redukovani galnom kiselinom.
FESEM i XRD analize su pokazale da nanolistići CuO organizovani u fine slojeve ravnomerno
pokrivaju površinu vlakana. Što je veća početna koncentracija NaIO4, veći je broj karboksilnih
grupa i posledično količina sintetisanih nanolistića CuO. Razvijeni tekstilni nanokompoziti su
pokazali odličnu antibakterijsku aktivnost prema Gram-negativnoj bakteriji Escherichia Coli i
Gram-pozitivnoj bakteriji Staphylococcus aureus, kao i zadovoljavajuću antifungalnu aktivnost
prema kvascu Candida albicans.
AB  - This study discussed the possibility of synthesizing Cu-based nanosheets on cotton fabric which could provide desired level of antimicrobial activity. In order to ensure a sufficient number of carboxyl groups that could efficiently bind Cu2+-ions from precursor salt solution, cotton fabric was selectively oxidized in two-step process with NaIO4 and NaClO2. Sorbed Cu2+-ions were reduced with gallic acid. FESEM and XRD analyses revealed that CuO nanosheets organized in fine layers evenly covered the surface of cotton fibers. The larger the initial concentration of NaIO4, the larger the number of carboxyl groups and consequently the amounts of synthesized CuO nanosheets. Fabricated textile nanocomposites exhibited excellent antibacterial activity against Gram-negative bacterium Escherichia Coli and Gram-positive bacterium Staphylococcus aureus as well as satisfactory antifungal activity against yeast Candida albicans.

abstract = "U ovom radu diskutovana je mogućnost sinteze nanolistića na bazi Cu na pamučnoj tkanini koji bi
pružili željeni nivo antimikrobne aktivnosti. Da bi se obezbedio dovoljan broj karboksilnih grupa za
vezivanje Cu2+
-jona iz rastvora soli prekursora pamučna tkanina je selektivno oksidisana u
dvostepenom procesu sa NaIO4 i NaClO2. Sorbovani Cu2+
-joni su redukovani galnom kiselinom.
FESEM i XRD analize su pokazale da nanolistići CuO organizovani u fine slojeve ravnomerno
pokrivaju površinu vlakana. Što je veća početna koncentracija NaIO4, veći je broj karboksilnih
grupa i posledično količina sintetisanih nanolistića CuO. Razvijeni tekstilni nanokompoziti su
pokazali odličnu antibakterijsku aktivnost prema Gram-negativnoj bakteriji Escherichia Coli i
Gram-pozitivnoj bakteriji Staphylococcus aureus, kao i zadovoljavajuću antifungalnu aktivnost
prema kvascu Candida albicans., This study discussed the possibility of synthesizing Cu-based nanosheets on cotton fabric which could provide desired level of antimicrobial activity. In order to ensure a sufficient number of carboxyl groups that could efficiently bind Cu2+-ions from precursor salt solution, cotton fabric was selectively oxidized in two-step process with NaIO4 and NaClO2. Sorbed Cu2+-ions were reduced with gallic acid. FESEM and XRD analyses revealed that CuO nanosheets organized in fine layers evenly covered the surface of cotton fibers. The larger the initial concentration of NaIO4, the larger the number of carboxyl groups and consequently the amounts of synthesized CuO nanosheets.

AB  - This study discusses the biodegradation behavior of cotton and cotton/PET fabrics impregnated with Ag/TiO2 nanoparticles in soil. Biodegradation behavior was evaluated by standard test method ASTM 5988-03 based on determination of percentage conversions of carbon content to CO2 as well as by soil burial test and enzymatic hydrolysis with cellulase where the extent of biodegradation was estimated by the calculation of fabric weight loss. The morphological and chemical changes of fibers during biodegradation process were analyzed by SEM and FTIR spectroscopy, respectively. The results obtained by all applied methods suggested that Ag/TiO2 nanoparticles hindered the biodegradation of investigated cotton and cotton/PET fabrics. Soil burial test indicated faster biodegradation of the impregnated blend compared to impregnated cotton fabric which is attributed to smaller amount of fabricated Ag nanoparticles on the blend proved by MS measurement. Similar trend was established by enzymatic hydrolysis of cotton fibers. Severe damage of cotton fibers in both fabrics due to biodegradation process was confirmed by SEM. However, the cotton fiber damage occurred to a lesser extent in the samples that were impregnated with Ag/TiO2 nanoparticles. PET fibers remained intact which was also indicated by FTIR analysis.

AB  - This study was aimed to elucidate the biodegradation behaviour of cotton and cotton/PET fabrics 
impregnated with Ag/TiO2 nanoparticles in soil. Biodegradation behaviour was assessed according to 
standard test method ASTM 5988-03 and soil burial test, where the extent of biodegradation was 
estimated by the calculation of fabric weight loss. The morphology of fibres affected by biodegradation 
was analysed by SEM. 
The results indicated that Ag/TiO2 nanoparticles inhibit the biodegradation of investigated cotton and 
cotton/PET fabrics. As expected, biodegradation of cotton fabric was considerably more pronounced 
compared to cotton/PET fabric. Larger inhibition of biodegradation of cotton fabrics impregnated with 
Ag/TiO2 nanoparticles compared to impregnated cotton/PET fabrics was not only due to the poor 
biodegradability of PET, but also because of significantly larger content of Ag in the cotton fabric. 
Severe damage of cotton fibres during the biodegradation process was also confirmed by SEM.

AB  - The possibility of in situ photoreduction of Ag+ using colloidal TiO2 nanoparticles deposited on the surface of polyamide fabric in the presence of the amino acid alanine and methanol is discussed. The presence of TiO2/Ag nanoparticles on the polyamide fabric was confirmed by FESEM and ICP analyses. The antibacterial activity of the fabric was tested against the Gram-negative bacterium Escherichia coli and the Gram- positive bacterium Staphylococcus aureus. The TiO2/Ag nanoparticles fabricated on the surface of the polyamide fabric provided maximum bacterial reduction and thus, excellent antibacterial activity. In spite of silver leaching from the fabric during washing, the impregnated polyamide fabric preserved the maximum reduction of E. coli colonies. The antibacterial activity against S. aureus was slightly decreased after ten washing cycles, but still the antibacterial activity could be considered as satisfactory. In addition, the presence of TiO2/Ag nanoparticles ensured better UV protection efficiency, which belonged to the UV protection category very good.
