Nanotechnology using biological principles provides wide range of novel antimicrobials resulting for the overcoming the antibiotic resistant bacterial strains. The usage of fungi for the development of silver based nanoparticles has added advantage that downstream processing and handling the biomass would be much simpler. Various species of Aspergillus included showing very good bactericidal effect which cannot be obtain by using conventional antibiotics. Further the results of color change, pH variations and uv spectra support the nanoparticle synthesis. The wide antimicrobial activity showed the need of rapid synthesis of nanoparticles would be suitable for the development of microbial nanotechnology biosynthesis process for the mass scale production.
