Biosynthesized silver nanoparticles (AgNPs) are environment friendly, cost-effective, bio-compatible and expanding research area due to their potential applications in medical domain. The present study focuses on biologically synthesized of AgNPs using aqueous root extract of  Iris germanica as reducing agent as well as capping agent and examined their potential antibacterial efficacy. In reduction reaction it was observed that silver (Ag+1) ions associate in root extract and reduced in solution (Ag0) leads to formation of stable formation of spherical AgNPs. Biosynthesized AgNPs showed an effective and rapid antibacterial activity against both bacterial strain (gram+ve and gram-ve). Results exhibited that AgNPs were extremely toxic towards Bacillus subtilis and Escherichia coli pathogenic bacterial strains and can be utilized for the applications in biomedical science.

The influence of technological factors on the regularities of obtaining silver nanoparticles using polyvinylpyrrolidone as reducing agent has been researched and its influence in compositions content on antimicrobial properties of last ones have been defined. The impact of temperature and polyvinylpyrrolidone content as well as Ag+ concentration on the kinetics of the reduction reaction of silver ions was determined. Silver-containing composites in the form of porous blocks and films were synthesized and their bactericidal and fungicidal properties were studied. The possibility of practical application of composites in biomedical area in the processes of osteogenesis has been confirmed.
