Marine micogenic systhesis of silver nanoperticles and their antimicrobial and cytotoxicity activity on textile gabric

Abstract:

The development of environmentally friendly processes for the synthesis of nanomaterials is nowadays an important topic of nanotechnology. A potential approach that has received special attention is based on the biosynthesis and application of metallic nanoparticles from microorganisms. In this work, we have investigated extracellular mycogenic synthesis of silver nanoparticles (AgNP) using thirty-one marine fungi. The biosynthesized AgNP were characterised and evaluated for their potential application in textile fabric. The AgNP characterisation analyses were carried out by UV-Vis spectroscopy, Dynamic Light Scattering (DLS) for particle size analysis, Zeta potential determination, transmission electron microscopy (TEM) and antimicrobial activity. Five AgNP samples presented great results on this set of analyses: IB-CLP11, IB-CLP13, IB-CLP14, IB-CLP17 and IB-CLP22. These five AgNP samples were adhered to cotton textile in different concentrations and exposed by fibroblast cells and all AgNP studied did not present any cytotoxic effect in the cells. Therefore, we consider the selected AgNP as very good options to add antimicrobial capacity to cotton textile fabric.
