Nanoparticles As Antibacterial Agents For Textile Finishing

Many synthetic compounds have been applied to impart antimicrobial properties to fabrics.In this review, the types of Nanomaterials in particular nanoparticles of inorganic metals and metal oxides are extensively used to functionalize natural, synthetic and regenerated polymers because of their effective antibacterial activity against different bacterial strains. The antibacterial activity of contact active surfaces is mainly due to its topography. If the surface has nano roughness like presence of nanorods, nanoparticles or any other nanostructure, the attaching bacteria on this surface will be killed due to penetration of these structures into membranes which leads to its disintegration. This mechanism is valid for all type of nanostructures whether they are inherently antibacterial or not. Like surface structures of many butterflies are not inherently antibacterial but their morphologies make them antibacterial . antimicrobial coating treatments on textiles, such as copper nanoparticles (CNPs) and silver nanoparticles (AgNPs) formed on plant extracts, chitosan and green synthesis, with a lower environmental impact but unaltered premium antimicrobial performance and improved durability.
