Antibacterial Silver Embedded Nanofibers for Water Disinfection

Silver : water disinfection and toxicity

Plasma treated activated carbon impregnated with silver nanoparticles for improved antibacterial effect in water disinfection

A strategy to selectively attach more Ag nanoparticles on the external surface of activated carbon (AC) is being proposed and used as an antibacterial medium for water disinfection. Ag nanoparticles were first synthesized under UV irradiation by reducing silver nitrate with sodium citrate; the latter serving the dual purpose of both a reducing and a capping agent. Transmission electron microgra...

Carboxymethylchitosan nanofibers containing silver nanoparticles: Preparation, Characterization and Antibacterial activity

Article history: Received on: 28/01/2016 Revised on: 17/03/2016 Accepted on: 18/05/2016 Available online: 28/07/2016 Herein we prepare antibacterial composite from carboxymethylchitosan (CMCS) nanofibers and silver nanoparticles (AgNPs) by using poly (vinyl alcohol) (PVA) as reducing, capping and fiber aiding material and investigated to be used in biomedical applications. The AgNPs has spheric...

Biogenic silver for disinfection of water contaminated with viruses.

The presence of enteric viruses in drinking water is a potential health risk. Growing interest has arisen in nanometals for water disinfection, in particular the use of silver-based nanotechnology. In this study, Lactobacillus fermentum served as a reducing agent and bacterial carrier matrix for zerovalent silver nanoparticles, referred to as biogenic Ag(0). The antiviral action of biogenic Ag(...

A new silver based composite material for SPA water disinfection.

A new composite material based on alumina (Al2O3) modified by two surface nanocoatings - titanium dioxide (TiO2) and silver (Ag) - was studied for spa water disinfection. Regarding the most common microorganisms in bathing waters, two non-pathogenic bacteria Escherichia coli (Gram-negative) and Staphylococcus epidermidis (Gram positive) were selected as surrogates for bacterial contamination.
