Abstract: The various side effects of the chemical drugs and their incapability to fight with the increasing drug resistance has led to the research for new antimicrobials which would be able to fight with fast evolving microbial army in a cost effective and efficient manner. The most promising source for this up to date is probably the nanoparticles among which the silver nanoparticles have the best potential till date. Silver has been used since time immemorial to treat cuts and burns and to treat wastewater but the effect of silver on human body in large dose may be toxic. The aim of this project is to identify the different types of sources from which the silver nanoparticles can be synthesised efficiently. Their comparative analysis has been done to compare their efficiency against Gram positive and Gram negative bacteria in the hope that further research would enlighten their uses more and a day may come when they would become our strongest fighter against microbial troops.

Keywords: antimicrobial activity; comparative analysis; green sources; silver nanoparticles.
