Biosynthesis of silver nanoparticles by Fusarium oxysporum

Silver nanoparticles have unique properties which help in molecular diagnostics, in therapies, as well as in devices that are used in several medical procedures. It is known that silver ions and silver based compounds are highly toxic to microorganisms which include 16 major species of bacteria. Silver nanoparticles are particles of silver of size between 1nm to 100 nm. They have gained significant consideration due to their unique characteristics and diverse applications. Fusarium oxysporum, potato dextrose broth and silver nitrate solution can be used for biological synthesis of silver nanoparticles. Colour change of fungal filtrate incubated with silver nitrate to yellowish brown depicted silver nanoparticle formation. These nanoparticles are used for delivery of drugs to their target sites at the right time to have a controlled release and achieve the maximum therapeutic effect.
