Dendritic systems in drug delivery applications.
The design of well-defined particulate carrier systems with controlled size, shapes and physicochemical characteristics is becoming a focal point in the field of biomedicine and drug delivery. Dendrimers are one of the emerging technologies of recent times and have served as a unique platform to achieve the development as novel drug delivery scaffolds. Dendrimers may be engineered to meet the specific needs of biologically active agents, which can either be encapsulated within dendrimers or chemically attached to these units. The large number of active functional groups on the surface of dendrimers allows them to be meticulously tailored and to act as nano-scaffolds or nano-containers of various categories of drugs. The architecture of modified dendrimers has posed a challenge to drug delivery, in particular with respect to their in vivo metabolic fate. The drug delivery applications of dendrimers presented in this article provide an insight of their potential and substantiate the major roles for the future of these nanoconstructs.
