Abstract
Due to the capacity to moderate metals to their nanometer size, nanobiotechnology is gaining enormous popularity in this period, which effectively changes its chemical, physical and optical properties. Recent progress in nanoscience and technology has also managed to the growth of new nanomaterials (NMs), eventually increasing toxic and potential health effects. There has been growing attention in evolving eco-friendly methods for metal nanoparticles (NPs) synthesis. The main purpose of the study is to reduce the harmful influences of synthetic processes, associated substances alongside other derivatives. The use of diverse biomaterials (BMs) for NP synthesis is examined as a promising method in green nanotechnology. However, most of the techniques currently available are costly; utilizing the natural properties includes plants, bacteria, fungi and algae to manufacture low-cost, non-toxic and energy-efficient metallic NPs that are environmentally friendly. Besides, biologically synthesized NPs and their characterization are essential for their future utility in numerous deliveries of drugs and pharmaceutical utilizations. Here, the current analysis summarizes the synthesis and future use of iron nanoparticles (Fe NPs) by green nanobiotechnology in the arena of biomedical applications.
