  • Publication number: 20230313170
    Abstract: Therapeutic extracellular vesicles (EVs) containing high copies of functional nucleic acids and other biomolecules are produced in large quantities by laying donor cells on a surface of a chip, adding various plasmids, other transfection vectors and their combinations to a buffer on the chip, applying a pulsulatic electric field across the cells laid on top of the chip surface and plasmids/vectors buffer solution below the chip surface, and collecting the EVs secreted by the transfected cells. The chip surface has a three-dimensional (3D) nanochannel electroporation (NEP) biochip formed on it, capable of handling large quantities of the donor cells. The buffer is adapted for receiving plasmids and other transfection vectors.
    Type: Application
