NANOTECHNOLOGY IN TARGETED DRUG DELIVERY SYSTEMS

Abstract

Nanotechnology has revolutionized the field of medicine, particularly in the development of targeted drug delivery systems. Unlike conventional drug administration methods that distribute medication non-specifically throughout the body, nanotechnology-based systems allow for precise delivery of therapeutic agents directly to diseased cells or tissues. This approach enhances treatment effectiveness, reduces side effects, and minimizes the required dosage. Nanoparticles—such as liposomes, dendrimers, polymeric nanoparticles, and metallic nanocarriers—are engineered to recognize specific biological targets through surface modifications and ligand-receptor interactions. These smart nanocarriers can respond to various physiological conditions, such as pH, temperature, or enzyme activity, ensuring controlled and sustained drug release. Furthermore, the integration of nanotechnology with imaging and diagnostic tools enables real-time monitoring of drug distribution and therapeutic outcomes. This multidisciplinary innovation not only improves the efficiency of modern pharmacotherapy but also opens new perspectives for personalized medicine and precision healthcare. The development of nanotechnology in targeted drug delivery systems represents a significant advancement in biomedical engineering, offering safer, more efficient, and patient-centered treatment strategies for complex diseases such as cancer, diabetes, and neurodegenerative disorders.
