Abstract

“Nanotheranostic” is an integrative approach to achieve diagnosis and therapeutic effect simultaneously, using nanocarriers. Nanotheranostic platform can be engineered to overcome biological barriers, to target the therapeutic agent at the required locus, and to support the monitoring of drug delivery. Dendrimers are well-defined 3D globular nanoarchitectured monodisperse system, pliable to precise size control and surface modification, which could serve as a potential nanotheranostic platform to achieve image-guided therapy, distribution monitoring, and drug targeting. Dendrimers exhibit biodegradable, biocompatible, and stimuli-responsive features that could ensure the anticipated biodistribution and efficacy. In this chapter, the utility of dendrimer as a theranostic nanoplatform embodying diversified category of therapeutic, imaging, and targeting moieties has been explored. Dendrimer-based administration of imaging agents (magnetic resonance imaging, computed tomography, single-photon emission computed tomography) along with its application in chemotherapy, pharmacodynamics therapy, and gene therapy has also been discussed.
