ABSTRACT

Metal nanoparticles (MNPs) are obtained using various synthesis techniques. This involves physical, chemical, biological, or a combination of them. Chemical reduction is one of the most frequently used methods of synthesis because it generates uniform-sized particles. This chapter provides an overview of MNPs and their synthesis process, the potential platform offered by NPs in various biological-related applications, the challenges associated with metallic NPs, and their future perspective. The most popular technique for creating MNPs is co-precipitation. Because it uses benign materials, it is frequently employed in biomedical applications. For a better understanding of the plants’ capacity to reduce metallic ions and to support the capping nature of MNPs produced by green synthesis, the mechanism of MNP production has been thoroughly investigated. The binding of biomolecules to the surfaces of MNPs during synthesis is assumed to be caused by green synthesis.
