ABSTRACT
The world has all sorts of challenges and the fate narrows down the challenges to those who are capable of handling them. True to it the crucial issue facing the scientific community in the treatment of deadly diseases such as cancer, Alzheimer’s, and so forth is the delivery of drug to the target site. Therefore, there is a growing interest to use nanotechnology in medicine and for drug delivery. Nanoparticles-based drug delivery system helps to strike a consistency between the drug-dose concentration and the resultant therapeutic outcome or toxic effects. Cell-specific targeting can be achieved by attaching drugs to specially designed carriers such as liposomes, metal nanoparticles, hybrid nanoparticles, and so forth. By successively addressing the encountered barriers such as nonspecific distribution and inadequate accumulation of therapeutics, innovative design features can be rationally incorporated to create a new generation of nanotherapeutics for realizing the exemplary shift in NP-based drug delivery. Therefore, the chapter deliberates over the potential of nanoparticles in the treatment of diseases such as cancer, Alzheimer’s, and so forth.
