The main drawback of biosynthesis of nanoparticles synthesis in eukaryotic organisms lies in the problem of genetic manipulation of the organism as a mean to over express the enzymes which is relatively much more difficult in eukaryotes than that in prokaryotes. Mukherjee et al demonstrated “green synthesis” of highly stabilized nanocrystalline silver particles by a nonpathogenic and agriculturally important fungus, Trichoderma asperellum 31.

Viruses in Nanoparticle Synthesis: Biological synthesis of nanoparticles has been extended to biological particles like viruses, proteins, peptides and enzymes. Cowpea chlorotic mottle virus and cowpea mosaic virus have been used for the mineralization of inorganic materials 35. Tobacco mosaic virus has shown to direct successfully the mineralization of sulphide and crystalline nanowires. One step further, peptides capable of nucleating Nano crystal growth have been identified from combinatorial screens and displayed on the surface of M13 bacteriophage 36.

Algae in Nanoparticles Synthesis: Algae are similar to yeast for biosynthesis of nanoparticle, still very few reports used algae as a “Biofactory” for the nanoparticles synthesis 32. The marine algae used for the biosynthesizing highly stable extracellular gold nanoparticles in a relatively short time period compare to other biosynthesizing process 32. Palladium and platinum nanoparticles starting with their corresponding metallic chloride- containing salts have been investigated 32.

Future Prospects: Nanoparticles are widely used to improve the various catalytic reactions due to their novel physico-chemical properties as compared to there bulk size components. Because of its their wide applications, there is need to produce nanoparticles in industries. As stated above the physical and chemical methods of nanoparticle synthesis are having many disadvantages. Biological synthesis would be a preferred method because of its environmental friendly approach 46.

The Lactobacillus strains present in the milk were exposed to larger concentration of nanoparticles to produced silver, gold, and alloy crystals of defined morphology 26. Bacteria have also been used to synthesize gold nanoparticles27. The PH was an important factory in controlling the morphology of bacteriogenic nanoparticles and location of the deposition. These nanoparticles were used in many application e.g. direct electrochemistry of proteins28. The most important application of bacterium would be in industrial silver recovery.
