ABSTRACT
The eventual goal of nanomedicine is to create and develop a system for illness prevention, diagnosis, control, and treatment. Nanoparticles can be engineered and programmed to have certain physical properties that protect the loaded medicine from degradation and/or denaturation by normal body processes while selectively delivering it to target locations with the desired cells. This successfully reduces the systemic exposure of the active pharmaceutical ingredient, and as a result, the occurrence of unwanted side effects. Through active targeting and controlled release technology, the entrapped drug molecules can be distributed and released more precisely, allowing for higher and accurate cellular uptake. The development of nano-based drug delivery systems is summarized in this chapter, with a focus on smart systems and the necessary features for the best drug nanocarrier.
