This research work deals with environment friendly technique for green synthesis of silver Nanoparticles from 1mM AgNO3 solution through the extract of Plectranthus amboinicus leaf .On mixing leaf extract with silver salt solution in ratio 1:9 the color changed from colourless to yellowish brown which partially confirmed the degradation of silver ions to silver nanoparticles (SNPs). Poly β Hydroxybutyrate (PHB) nanoparticle is a biodegradable polymer produced by several bacteria and it has many medical applications. The synthesized nanoparticles were characterized by using UV–visible spectroscopic techniques, Scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FT-IR). The antimicrobial activities of the synthesized silver Nanoparticles and PHB Nanoparticles against microorganisms were evaluated by using disc diffusion method. Conventional cotton gauze treated with nanocomposites for achieveing antimicrobial activity and its efficiency.
