Preparation of silver nanoparticles have been carried out using aqueous extract of lemon leaves ( Citrus limon ) which acts as reducing agent and encapsulating cage for the silver nanoparticles. These silver nanoparticles have been used for durable textile finish on cotton and silk fabrics. Remarkable antifungal activity has been observed in the treated fabrics. The antimicrobial activity of silver nanoparticles derived from lemon leaves showed enhancement in activity due to synergistic effect of silver and essential oil components of lemon leaves. The present investigation shows the extracellular synthesis of highly stable silver nanoparticles by biotransformation using the extract of lemon leaves by controlled reduction of the Ag + ion to Ag 0 . Further the silver nanoparticles were used for antifungal treatment of fabrics which was tested by antifungal activity assessment of textile material by Agar diffusion method against Fusarium oxysporum and Alternaria brassicicola . Formation of the metallic nanoparticles was established by FT–IR, UV–Visible spectroscopy, transmission electron microscopy, scanning electron microscopy, atomic force microscopy.
