Green Synthesis of Nanoparticles in Biomedicine

The green or bio synthesis of nanoparticles (NPs) has developed as a conservational and economical alternative to conventional chemical methods, especially in the field of biomedicine. This chapter explores the various green synthesis methods employed for the synthesis of nanoparti cles, highlighting biological agents such as plant extracts, microorganisms, and enzymes that facilitate nanoparticle production. It further delves into the characterization techniques used to determine the size, shape, surface charge, and functional properties of the synthesized nanoparticles, with an importance on techniques like UV-Vis spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and dynamic light scat tering (DLS). Additionally, the chapter discusses the varied biomedical applications of green-synthesized nanoparticles, including drug delivery, wound healing, cancer therapy, antimicrobial activity, and tissue engi neering. By concentrating on the benefits of green synthesis, this chapter summaries the potential of these nanoparticles in advancing biomedical technologies while minimizing the ecological and health risks associated with conventional synthetic approaches.
