Fabrication of Antimicrobial Cotton Fabrics by Treating with Biogenic Metal Nanoparticles and their Effect on Clinical Pathogens

In order to produce the highly potential antimicrobial cotton fabrics a biological oriented nanoparticles-treatment process was adopted in this study. Six different metal (Ag, Au, Zn, Cu, Mg and Ca) nanoparticles (NPs) were synthesised by using a Mangrove plant Xylocarpus mekongensis Pierre leaves extract and these NPs were coated to cotton fabrics and further assessed their antibacterial activity against clinical pathogens. The SEM photographs revealed the presence of fabricated NPs on cotton fabrics. The biogenic NPs coated cotton fabrics were inhibited all the test clinical pathogens. Among the different type of NPs coated cotton fabrics, the Au NPs coated cotton fabrics showed the higher inhibition zone of 22.5 mm diameter against Salmonella typhi whereas Zn NPs coated cotton fabric showed the lowest inhibition zone of 6 mm against Proteus mirabilis. This present work emphasizes the possible usage of biogenic metal NPs in fabrication of antibacterial cotton fabrics.
