Nanobiotechnologies for stroke treatment.

Stroke has brought about a poor quality of life for patients and a substantial societal burden with high morbidity and mortality. Thus, the efficient stroke treatment has always been the hot topic in the research of medicine. In the past decades, nanobiotechnologies, including natural exosomes and artificial nanomaterials, have been a focus of attention for stroke treatment due to their inherent advantages, such as facile blood - brain barrier traversal and high drug encapsulation efficiency. Recently, thanks to the rapid development of nanobiotechnologies, more and more efforts have been made to study the therapeutic effects of exosomes and artificial nanomaterials as well as relevant mechanisms in stroke treatment. Herein, from recent studies and articles, the application of natural exosomes and artificial nanomaterials in stroke treatment are summarized. And their prospects of clinical translation and future development are also discussed in further detail.
