Biomineralization has endowed many organisms with peculiar functions under the modification of the inorganic nanostructure biosynthesized under the mediation of the cells. Recently, with the development of biosynthesis and nanotechnology, using organisms to synthesize nanomaterials has attracted the wide attention of researchers. Compared with traditional physical and chemical synthesis methods, biosynthesis has the advantages of simple operation and environmental friendliness. So far, there have been many studies on the use of bacteria, fungi, some plants and human cells to successfully produce various shapes and sizes of inorganic nanomaterials. The obtained nanomaterials not only have good dispersibility and stability, but also have excellent application performance. Hence, it is widely used in the fields of catalysis, electrology, optics and biomedicine, etc. The biomimetic mineralization synthesis of nanoparticles is likely to provide scientific reference for the discovery of novel nanomaterials. This review presents the related knowledge of biological nanotechnology and the research progresseof nanomaterials synthesized by different organisms. The current main problems of biosynthetic nanomaterials, progress of research contents and innovation points of are elaborated in detail.
