Abstract

Nanomedicine, a rapidly evolving discipline at the intersection of nanotechnology and medical sciences, has significantly enhanced drug delivery systems and therapeutic applications. By leveraging nanoscale materials and mechanisms, nanomedicine has overcome many traditional therapeutic limitations, including poor bioavailability, systemic toxicity, and nonspecific targeting. The versatility of nanoparticles enables precise drug delivery, controlled release, and enhanced therapeutic efficacy. This paper provides an overview of recent advancements in nanomedicine, focusing on drug delivery systems, including liposomes, polymeric nanoparticles, and dendrimers. We also explore their applications in treating cancer, infectious diseases, and chronic conditions. While nanomedicine offers transformative potential, challenges such as scalability, regulatory hurdles, and long-term safety remain. Future directions are proposed to address these challenges and maximize the clinical impact of nanotechnology.
