Abstract: Nanotechnology has revolutionized the field of medicine, particularly in targeted drug delivery and treatment. The unique properties of nanoparticles, such as their small size, large surface area, and ability to be functionalized with various biomolecules, make them ideal candidates for delivering drugs directly to diseased cells, enhancing therapeutic efficacy while minimizing side effects. This paper explores the different types of nanoparticles used in drug delivery, including lipid-based, polymeric, metallic, and dendrimer nanoparticles. It also discusses the mechanisms of drug delivery, such as passive and active targeting, and nanoparticle functionalization techniques. Applications of nanotechnology in treating cancer, cardiovascular diseases, neurological disorders, and infectious diseases are examined. The paper also addresses the challenges faced in the clinical application of nanoparticles, such as toxicity, biocompatibility, manufacturing, and regulatory hurdles. Finally, it highlights future perspectives, including personalized medicine, combination therapies, and smart nanoparticles, which hold promise for further advancements in this field.
