Abstract
Nanotechnology, as an important branch of modern science and technology, has provided new ideas and solutions for the development of drug delivery systems. This study aims to explore the application mechanisms of nanotechnology in drug delivery and its future prospects by analyzing the characteristics, preparation methods, and biological effects of nanocarrier materials, evaluating their potential to improve drug targeting, reduce toxic side effects, and enhance therapeutic efficacy. The research combines experimental validation with theoretical analysis, selecting various typical nanocarriers such as liposomes, polymeric nanoparticles, and inorganic nanoparticles for in vitro and in vivo experiments to examine their drug-loading capacity, release behavior, and biocompatibility. The results indicate that nanotechnology can significantly address the limitations of traditional drug delivery systems, enabling controlled release and precise delivery of drugs. Particularly in cancer therapy, nanotechnology-based drug delivery systems demonstrate superior efficacy and safety. An innovation of this study lies in the first proposal of a multifunctional nanocarrier design strategy that integrates active targeting and stimuli-responsive release functions, effectively enhancing drug accumulation at lesion sites. Furthermore, the study provides an outlook on the potential value of nanotechnology in personalized medicine and combination therapies, laying a theoretical foundation and practical guidance for further advancements in related fields.
