Application of carbon and metal-based nanomaterials in modern health care systems

Nanotechnology has significance in modern health care technologies due to the potential of these materials at nano levels. Due to their decreased volumes, complex morphologies, and controllable exposed crystal facets, metallic nanocrystals (MNCs) demonstrate superior properties to their bulk equivalent. Consequently, the manufacturing of metal nanocrystals and their modification for various applications have drawn significant benefits. Among different nanoparticles, MNCs are of wider applications in diverse biomedical field. Various studies have been carried out over the past 40 years to synthesize, evaluate, and distribute metallic nanoparticles for different forms of medicinal and therapeutic applications. This chapter gives an overview of applications in both magnetic and nonmagnetic MNCs in modern healthcare systems.
