Applications, Biomedical Necessities, and Green Future of Metallic Nanoparticles

Metallic nanoparticles like gold nanoparticles (AuNPs), magnetic iron oxide nanoparticles (Fe3O4 ), and cysteine-capped silver nanoparticles (Cyanopes) are changing the face of green nanotechnology. Their photonic capabilities, ultrafine size ( 10-100 nanometers), biocompatibility, diamagnetic strength, antibacterial activity, and photochemical qualities make them extremely useful in medical applications, radiotherapies, drug delivery, cosmetics, and solar cell coatings. This chapter provides a comprehensive outlook on the applications, biomedical necessities, and green future of metallic nanoparticles. The current discussion revolves around graphene-based nanofillers, focusing on their ability to enhance the tribological properties of aluminum and its alloys within the realm of materials research. Thin metallic tin sulfide nanoparticles and titanium oxide nanorods, on the other hand, play an important role in photochemical water splitting. Modern nanotechnology is advancing biological processes by allowing for a thorough examination of metallic nanoparticle forms as highlighted in the chapter. A notable application incorporates a nanoscale metallic lattice that facilitates the transfer of cisplatin and siRNA, showing great promise in resensitizing ovarian tumors. This chapter provides an exhaustive analysis of the potentials, benefits, and challenges associated with metallic nanoparticles, emphasizing their extensive applications and crucial role in the advancement of various fields.
