Cancer Nanotechnology: Nanotechnology-Based Drug Delivery Approaches For Cancer

Cancer continues to be one of the deadliest diseases and a leading cause of death globally. Detecting it early and providing prompt treatment are crucial strategies in combating cancer. Over the last few years, progress has been made across the nanomedicine landscape, in particular, the invention of contemporary nanostructures for cancer diagnosis and overcoming complexities in the clinical treatment of cancerous tissues. Nanomedicine is a prominent area of nanotechnology research that applies nanoscale techniques to create precise medical solutions for diagnosing, preventing, and treating diseases. Nanotechnology offers targeted release of drugs that maximizes the therapeutic index and minimizes system toxicity. Because of its wide-ranging uses, nanotechnology holds great potential for identifying cancer cells, detecting cancer biomarkers, and providing effective treatment. Nanomedicines improve drug bioavailability and reduce systemic toxicity, offering more effective and precise cancer therapies. This review offers an in-depth analysis of different approaches in nano-delivery systems for chemotherapy drugs. It highlights how nanoparticle-based carriers enhance drug targeting, improve therapeutic effectiveness, and reduce side effects by selectively delivering anticancer agents to tumor tissues. This review discusses the ability of nanotechnology to overcome drug resistance mechanisms, thereby paving the way for the development of more effective and safer anti-tumor drugs.
