Exosomes are nanoscale extracellular vesicles that encapsulate a diverse range of biomolecules
such as nucleic acids, proteins, and lipids. They are involved in several biological processes
and mediate intracellular communication. Recent reports that they exhibit unique traits in
pathological conditions have generated significant interest in employing them as diagnostic and
therapeutic tools. Particularly, their potential to serve as drug delivery vehicles for the treatment of
cancer and other diseases has been explored in numerous studies. This manuscript reviews recent
developments in the field and discusses important considerations for further refinement of this approach
and realization of more effective exosome-based drug delivery systems.
Keywords: Extracellular vesicles, drug delivery, nanotechnology, targeted therapy, chemotherapy, nanocarriers.
