Abstract
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.
