Nanotechnology has a number of advantages as medication delivery technologies that increase efficacy and prevent negative drug reactions. Pharmaceutical nanotechnology provides state-of-the-art equipment, know-how, opportunity, and scope in many facets of the healthcare sector. It is currently well-established as a specialised sector for medication delivery, diagnostics, prognostics, and numerous treatment processes thanks to its nano-engineered instruments and methodologies. Nanoparticles are used in the production of COVID-19 vaccines as well as the treatment of kidney disorders, tuberculosis, skin conditions, Alzheimer's disease, and other malignancies.
