AB  - Antibacterial and antifungal ability of silver nanoparticles (Ag NPs) supported by functionalized magnetite (Fe3O4) with 5-aminosalicylic acid (5-ASA) was tested against Gram-negative bacteria Escherichia coli, Gram-positive bacteria Staphylococcus aureus and yeast Candida albicans. Characterization of materials including transmission electron microscopy, X-ray diffraction analysis, and inductively coupled plasma optic emission spectroscopy technique followed each step during the course of nanocomposite preparation. The synthesized powder consists of 30-50 nm in size silver particles surrounded by clusters of smaller (~10 nm) Fe3O4 particles. The content of silver in the nanocomposite powder was found to be slightly above 40 wt.-%. Concentration-dependent and time-dependent bacterial reduction measurements in dark indicated that use of Ag NPs leads to the complete reduction of E. coli and S. aureus even at the concentration level of silver as low as 40 μg/mL. However, the negligible antifungal ability of synthesized nanocomposite was found against yeast C. albicans in the entire investigated concentration range (0.1-2.0 mg/mL of the nanocomposite, i.e., 40-800 μg/mL of silver). Complete inactivation of E. coli and S. aureus was achieved in five repeated cycles indicated that synthesized nanocomposite can perform under long-run working conditions. From the technological point of view, magnetic separation is the additional advantage of synthesized nanocomposite for potential use as an antibacterial agent.

AB  - This study was aimed to highlight the possibility of in situ generation of Ag nanoparticles on polyester fabric by photoreduction of Ag+ ions with deposited TiO2 nanoparticles in the presence of amino acid alanine and methyl alcohol. The presence of TiO2/Ag nanoparticles on the polyester fibers was proved by XRD, XPS and SEM analyses. Such nanocomposite textile material provides extraordinary antimicrobial activity against Gram-negative bacterium E. coli, Gram-positive bacterium S. aureus and fungus C. albicans. Maximum microbial reduction was maintained after ten washing cycles. Despite good laundering durability, the leaching of silver occurred during washing. Silver release was also detected during the 24 hours long incubation at 37o C in artificial sweat at pH 5.5 and 8.0. In addition to excellent antimicrobial properties, TiO2/Ag nanoparticles provided maximum UV protection to polyester fabrics.

AB  - The aim of this study was to compare the effects of corona discharge at atmospheric pressure and air RF plasma at low pressure activation of cotton fabrics prior to deposition of colloidal TiO2 nanoparticles in order to enhance antibacterial, UV protective and photocatalytic properties. X-ray photoelectron spectroscopy analysis proved the presence of TiO2 nanoparticles on the surface of cotton fibres. Atomic absorption spectroscopy measurements demonstrated that content of TiO2 in the cotton fabrics pre-treated by corona and RF plasma was 31 % higher than in the fabric that did not undergo any treatment prior to loading of TiO2 nanoparticles. In order to obtain maximum reduction of Gram-negative bacteria E. coli, untreated cotton fabric had to be loaded with colloidal TiO2 nanoparticles twice, but only once following the corona or air RF plasma pre-treatment. Loading of cotton fabrics with TiO2 nanoparticles ensured maximum UV protective rating of 50+. Excellent photocatalytic activity of TiO2 nanoparticles deposited onto cotton fabrics was confirmed by photodegradation of dye methylene blue in aqueous solution under UV illumination.
