Small extracellular vesicles (sEV) play an irreplaceable role in cell-cell communication. However, sEV in solution aggregate with each other during preservation, leading to impairment of the structures, contents, and functions of sEV. Therefore, there is a need to develop an optimal preservation method that combines high recovery rate, low cost, convenience, and easy-transportation in one. In this study, a new preservation strategy different from the cryopreservation or lyophilization was developed by reducing sEV particles aggregation.
