Background: Due to the rapid growth in life threatening diseases such as cancer, diabetes, chronic wound and HIV/AIDS along with rise of side effects of the current treatments, world is now focusing to utilize new treatment options. Currently, the development of green nanotechnology field seems as a potential alternate for diseases diagnosis and treatment by preparation of various sizes and shapes of nanomaterials.
Objective: This review is to present the explored biological sources in synthesis of nanomaterials particularly metal and metal oxides nanoparticles and critical review of the applications of biosynthesized nanoparticles in pharmaceutical and biomedical fields.
