Abstract:: Bio synthesis of nano crystal has particular characters such as bio optical, electrical, photochemical and other properties, which have opened up new fields in application of nanomaterials. Biosynthesis of nanocrystals mainly uses biological molecules, microbes, plants and their extracts as coat in the reduction system. There are more advantages of biosynthetic nanoparticles such as a wide source of raw materials, mild reaction conditions, nonagglomerated nanoparticles, and less toxic byproducts. Biosynthesis of nanocrystal is to add biological molecules (microbes such as fungi, microzyme , actinomyceto, bacterium, plants and their extracts) as coat into the synthesis system, as the biological molecules can absorb on the surface of the nanoparticles to keep off congregation, and can endow them with biocompatibility for application in biomedicine and foodstuff detection. Methods for biosynthesis of nanocrystal using microorganism, plants and their extracts have been reviewed, and features of nanocrystals synthesized by different biological reduction processes have been summarized and forecasted, based on domestic and foreign research literature on nanocrystal synthesis, in the hope of giving references to study on biosynthesis of nanocrystal.
