Revolutionizing Cancer Care Through Smart Drug Delivery Technologies

Abstract: Smart materials that react to environmental stimuli, such as temperature, pH, light, or electromagnetic fields are transforming cancer treatment by enabling precisely controlled drug release. Nanoparticle-based delivery systems enhance drug solubility, prolong circulation time, and concentrate therapeutics at tumor sites, mitigating damage to healthy tissues. Stimuli-responsive systems triggered by internal or external cues offer spatiotemporal control over release, improving safety and efficacy. This review outlines recent advances in smart nanocarriers for cancer therapy, examines their mechanisms, highlights clinical successes, addresses current challenges, and explores future directions including AI-driven personalization and emerging nanotechnologies.
