Biosynthesis of selenium nanoparticles by Aspergillus niger

Nanoparticles can be synthesized by biological, chemical and physical methods. There are several disadvantages of physical and chemical synthesis methods which include release of hazardous and toxic effluents and higher cost of production. The use of microbial factories for the production of nanopar...
