Silver nanoparticles synthesized by a cost-effective three-stage electrochemical technique have demonstrated great promise as antimicrobial agents. Nanosilver was less effective against E. coli, S. aureus, B. subtilis and P. phoeniceum compared to silver ions. However silver nanoparticles have prolonged bactericidal effect as a result of continuous release of Ag ions in sufficient concentration and thus nanoparticles can be more suitable in some bactericidal applications. The synthesized silver nanoparticles added to water paints or cotton fabrics have demonstrated a pronounced antibacterial/antifungal effect, despite the fact that they tend to agglomerate into clusters up to 200 nm. 

Silver Nanoparticles. Silver nanoparticles have been found to have very good antibacterial action, and are being used to impregnate bandages they are also used to impregnate socks and added to underarm deodorants because the antibacterial action kills the bacteria responsible for the unpleasant smells.

In another study Escherichia coli cells treated by Ag nanoparticles were found damaged, showing formation of pits in the cell wall of the bacteria (59). Jain and Pradeep have studied the efficacy of silver nanoparticles as a drinking water filter where there is bacterial contamination of the surface water (60). Silver nanoparticles were utilized to make stable, silver-coated filters from common polyurethane (PU) foams. The performance of the material as an antibacterial water filter was checked and no bacterium was detected in the output water when the input water had a bacterial load of 1 X 10 colony-forming units (CPU) per miUditer. The antibacterial action was also checked inline for a flow rate of 0.5 L/min and no bacterium detected, which suggests that domestic use of this technology is possible.

Silver-based biocides are also gaining a share in plastics markets, especially in Japan, where silver ions supported in inorganic matrix/substrates (such as zeolites or alumina-silica), are often used in hospital settings. Silver-nanoparticle-coated PU foams have been shown to be effective antibacterial water filters [46].

The literature confirms that attempts to clarify the mechanism of silver nanoparticle action against bacteria, viruses, and fungi have been taken. One of the most common mechanisms of nanosilver antibacterial activity is based on its natural affinity for bonding with a thiol group present in cysteine, which is a protein building material of bacterial cell walls. Consequently, the enzymatic function of the proteins is disturbed and the cellular respiration chain is interrupted. At the same time other enzymes such as NADH and succinate dehydrogenase are destroyed (Park et al., 2009).
