From: Strategies to overcome the main challenges of the use of exosomes as drug carrier for cancer therapy
The preference of exosomes to be used as a suitable drug carrier technology. Characteristics like as biocompatibility, precise targeting, and sustained circulatory capacity make these nanomaterials appropriate for delivery. Furthermore, it has become a top candidate for drug and bioactive molecule transport due to its high selectivity, low immunogenicity, and low toxicity; it can cross the cytoplasmic membrane and the blood brain barrier
