NANOTECHNOLOGY IN DRUG DELIVERY SYSTEMS: TARGETED THERAPEUTICS FOR PRECISION MEDICINE

Abstract

Nanotechnology has emerged as a transformative force in drug delivery, offering precision targeting, enhanced bioavailability, and reduced systemic toxicity. By engineering nanocarriers at the molecular scale, it becomes possible to overcome traditional therapeutic limitations such as poor solubility, nonspecific distribution, and rapid degradation. These advancements hold profound implications for precision medicine, particularly in the treatment of cancer, neurological disorders, and infectious diseases.In this study, a comprehensive analysis was conducted on various nanocarrier systems including liposomes, polymeric nanoparticles, micelles, and dendrimers. These systems were evaluated based on parameters such as particle size, surface charge, drug loading efficiency, and release kinetics. Methodologically, the study applied both experimental data synthesis and computational modeling to assess nanocarrier performance under diverse physiological conditions. Smart nanocarriers—responsive to pH, temperature, enzymes, and magnetic fields—were also considered for their controlled release capabilities and site-specific delivery potential.The results demonstrate that functionalized nanocarriers significantly improve therapeutic index by enhancing drug retention at target sites and minimizing off-target effects. Smart stimuli-responsive carriers exhibited superior performance in dynamic release and payload control. Bioavailability, targeting specificity, and drug release profiles were consistently optimized across the tested platforms, validating the adaptability and efficacy of nanotechnology in drug delivery.In conclusion, the integration of nanotechnology into therapeutic protocols represents a major leap toward individualized, responsive, and minimally invasive treatment modalities. Future innovations such as AI-assisted nanocarrier design, real-time adaptive delivery, and patient-specific formulation hold the promise of revolutionizing modern pharmacotherapy and enabling truly personalized medicine..
