Exosomes are extracellular nanovesicles. They innately possess ideal structural and biocompatible nanocarrier properties. Exosome components can be engineered at the cellular level. Alternatively, when exosome source cells are unavailable for customized exosome production, exosomes derived from a variety of biological origins can be modified post isolation which is the focus of this article. Modification of exosome surface structures allows for exosome imaging and tracking in vivo. Exosome membranes can be loaded with hydrophobic therapeutics to increase drug stability and efficacy. Hydrophilic therapeutics such as RNA can be encapsulated in exosomes to improve cellular delivery. Despite advances in post isolation exosome modification strategies, many challenges to effectively harnessing their therapeutic potential remain. Future topics of exploration include: matching exosome subtypes with nanomedicine applications, optimizing exosomal nanocarrier formulation and investigating how modified exosomes interface with the immune system. Research into these areas will greatly facilitate personalized exosome-based nanomedicine endeavors.
