“…Not only in pharmaceutical and medical-based products but also in the production of daily consumer products like soaps, toothpaste, detergents, cosmetic products, etc., noble metal nanoparticles (such as silver, palladium, gold, etc.) have found wide application. , Nanoparticles (NPs) of gold find significant application in medicine − as they play important roles in delivery of drugs and diagnosis of various diseases . Furthermore, nanoparticles of silver play an important role in biological-based equilibrium, technology based on sensors, and various other applications related to biomedicine. − Nanoparticles of platinum find usage as catalysts, − besides being used with other nanoparticles in the field of biomedicine as alloys, shell of core, and other nanostructures that are bimetallic in nature. , In the same way, nanoparticles of palladium play a major role in plasmonic-based wave guiding, sensing, , and electrocatalysis and catalysis. − …”
