Nanoengineering of extracellular vesicles for drug delivery systems: Current advances and future directions

Abstract

Extracellular Vesicles (EVs) have gained high repute in drug delivery systems owing to their relatively higher efficacy as natural drug delivery vehicles. The current literature has advanced the use of EVs in drug delivery through exploring various aspects including their biogenesis, characterization, and nanoengineering techniques thereby leading them from laboratory to clinical use with optimized good laboratory practices. In this timely review, we summarize the current status of EVs characterizations and recent updates on nanoengineering of EVs regarding Cargo loading and surface fabrication. Further, we have also reviewed current progress in clinical translation and implications of EVs in clinical trials together with future recommendations.
