Extracellular biosynthesis of silver nanoparticles using the fungus Fusarium oxysporum
Absar Ahmad,Priyabrata Mukherjee,Satyajyoti Senapati,Deendayal Mandal,M. Islam Khan,Rajiv Kumar,Murali Sastry +6 more
TL;DR: It is observed that aqueous silver ions when exposed to the fungus Fusarium oxysporum are reduced in solution, thereby leading to the formation of an extremely stable silver hydrosol, creating the possibility of developing a rational, fungal-based method for the synthesis of nanomaterials over a range of chemical compositions, which is currently not possible by other microbe-based methods.
