ABSTRACT
The green synthesis route has gained enormous attention worldwide as this domain independently emerged as one of the most promising scientific solutions for various technological challenges due to its consistency, reliability, and cost-effectiveness with wide applications in the areas of medical sciences, biotechnology, pharmaceuticals, material science, and bioelectronics. Among various nanoparticles, metallic nanoparticles (MNPs) are efficiently targeted for drug delivery, cancer treatments, photothermal therapy, and infectious and neurological disorders, and this has created apprehension among many researchers. MNPs for various morphologies have been synthesized via green synthesis using biological materials such as microorganism (bacteria, fungi, algae, virus), plant extracts, and polymers as well as it provides excellent surface functionalization properties. MNPs have been used as catalysts for the efficient degradation of organic contaminants/methylene blue (MB). For characterization, UV-Vis spectra depict the degradation of MB when exposed in solar energy for various interval of time. This chapter focuses on the use of MNPs in biomedical applications and environmental remediation.
