Abstract
Nanotechnology in drug delivery has revolutionized modern therapeutics by addressing the limitations of conventional drug delivery methods. This review article explores the significant advancements in nanoparticle-based drug delivery systems, highlighting their role in enhancing therapeutic efficacy and overcoming drug resistance. Nanoparticles, including lipid-based, polymer- based, inorganic, and biological types, offer improved solubility, stability, targeted delivery, and controlled release of therapeutic agents. By enabling precise delivery to specific tissues or cells, these advancements minimize off-target effects and toxicity, particularly in cancer therapy. Additionally, nanomedicine facilitates the delivery of drugs across biological barriers such as the blood-brain barrier, which opens new avenues for treating neurological disorders. The ability to co-encapsulate multiple therapeutic agents in nanoparticles also supports combination therapies that target multiple pathways simultaneously, thereby reducing the development of resistance. As research progresses, the integration of nanotechnology in drug delivery promises to transform healthcare by providing more effective, safer, and personalized treatments. This article advocates for continued exploration and innovation in the field by emphasizing the need for interdisciplinary collaboration to fully realize the potential of nanomedicine in improving patient outcomes and addressing unmet clinical needs.
