ABSTRACT
Recently, drug delivery is one of the main challenges for the development of new pharmaceutical applications in the eld of nanotechnology. Many drugs have physicochemical characteristics that are not favorable to pass biological/enzymatic barriers within the human body. Thus, the development of carriers for drug delivery has seen a signicant increase in the last 20 years. Prodrugs, soft drugs, and codrugs are designed to transport efcient and selective drugs to the site of action and to achieve therapeutic efciency as well as treatment safety [1]. Liposomes, dendrimers, smart polymers, as well as viral nanoparticles (VNPs) are used as tools for potent delivery of therapeutics [2]. In the rst part of this chapter, we present the current state of progress regarding the main tools for potent drug delivery. In the second part of this chapter, we particularly focus on virus-based nanoparticles as drug delivery systems.
