Targeted Nanoparticle-Based Drug Delivery Systems: Enhancing Therapeutic Efficacy in Cancer Treatment

Cancer remains a significant cause of illness and death globally, regardless of the level of human development. One key strategy in cancer treatment is the targeted delivery of drugs directly to tumor sites. Recent advancements in nanotechnology have opened new avenues for researchers to enhance cancer therapies. Nanoparticles are defined as particles with a size smaller than 0.1 µm, or 100 nm. They play a crucial role in improving the delivery and uptake of medications in targeted cells. There are two primary methods for synthesizing nanoparticles: the bottom-up method and the top-down method. When it comes to delivering therapeutic nanoparticles to targeted areas, two main strategies are utilized: passive targeting and active targeting. Passive targeting relies on the natural accumulation of nanoparticles within solid tumors, while active targeting enhances the binding of nanoparticles to specific antigens.
