This research paper explores the pivotal role of nanotechnology in revolutionizing drug delivery systems, aiming to enhance therapeutic efficacy, reduce side effects, and improve patient compliance. By leveraging the unique properties of nanoscale materials, this study delves into the mechanisms of targeted drug delivery, controlled release, and improved solubility that nanotechnology facilitates. The paper reviews various nano-carriers, including nanoparticles, liposomes, dendrimers, and polymeric micelles, and their applications in treating a wide range of diseases such as cancer, cardiovascular diseases, and neurodegenerative disorders. Through a comprehensive literature review, this study highlights the significant advantages of nanotechnology in drug delivery, such as enhanced permeability and retention (EPR) effect, passive and active targeting, and the overcoming of biological barriers. It also addresses the challenges and limitations, including toxicity, regulatory hurdles, and the scalability of nano-technological methods. By presenting recent advances and future directions, this paper underscores the transformative potential of nanotechnology in drug delivery, promising a new era of personalized medicine and improved health outcomes.
