The effect of biologically and chemically synthesized silver nanoparticles (AgNPs) on biofilm formation

Abstract

Abstract. Bionanotechnology has emerged up as integration between biotechnology and nanotechnology for developing biosynthetic and environmental-friendly technology for synthesis of nanomaterials. Different types of nanomaterials like copper, zinc, titanium, magnesium, gold, and silver have applied in the various industries but silver nanoparticles have proved to be most effective against bacteria, viruses and eukaryotic microorganisms. The antimicrobial property of silver nanoparticles are widely known. Due to strong antibacterial property silver nanoparticles are used, e.g. in clothing, food industry, sunscreens, cosmetics and many household and environmental appliances. The aim of the study was to compare the effect of silver nanoparticles (AgNPs) synthesized biologically and chemically on the biofilm formation. The biofilm was formed by the bacteria isolated from the water supply network. The commonly used crystal violet assay (CV) was applied for biofilm analysis. In this study effect of biologically synthesized Ag-NPs on the biofilm formation was evaluated.

“…In addition silver Nanoparticles can be synthesized by diversity of different approaches such as physical, chemical and biological. The latter one is greatest favorable method because it security, less toxicity and ecofriendly to environment but, the chemical and physical methods are very expensive, may have a poisonous and dangerous materials (2). Green synthesis of Nanoparticles (NPs) by bacteria has several advantages due to its essential ecofriendly and economical nature, green biosynthesis suggestions an another approach which can substantially overawed the environmental challenges posed by physical and chemical methods (3; 4).…”
