Nanotechnology Meets Targeted Therapy: Engineering Nanoparticles for Enhanced Drug Delivery
Year: 2024
Type: article
Abstract: Nanoparticle-based targeted drug delivery systems have transformed therapeutic strategies by offering precise and controlled drug delivery to specific sites within the body, thereby enhancing treatment efficacy while reducing systemic side effects. Due to their unique properties—such as small size, high surface area, and the ability to be functionalized with targeting ligands—nanoparticles enable both passive and active targeting. Passive targeting utilizes the enhanced permeability and retention (EPR) effect, while active targeting leverages ligand-receptor interactions for precise localization. This review focuses on key types of nanoparticles used in drug delivery, including polymeric nanoparticles, liposomes, solid lipid nanoparticles, and metallic nanoparticles, each offering unique advantages for targeted delivery. Recent advancements in responsive nanoparticles—designed to release drugs in response to specific stimuli, such as pH or temperature—have further optimized therapeutic delivery, particularly in cancer treatment. While nanoparticle-based delivery systems hold immense potential, challenges such as biocompatibility, toxicity, stability, and regulatory hurdles remain. Addressing these issues through advanced research and clinical trials is essential for translating this technology into safe, effective therapies. In summary, nanoparticle-mediated targeted drug delivery presents a promising future for precision medicine, offering tailored treatments across a spectrum of diseases.
