Nanotechnology enhances drug delivery by allowing the development of nanoscale carriers such as liposomes, dendrimers, and polymeric nanoparticles. These carriers can be engineered to have specific physical and chemical properties, enabling them to overcome biological barriers, release drugs in a controlled manner, and target specific cells or tissues. For instance, targeted drug delivery systems can be designed to recognize and bind to specific cell surface markers, ensuring that the therapeutic agents are released only in the vicinity of diseased cells.
