  • 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.

  • Patent number: 10100300
    Abstract: A simple and low cost method of producing sealed arrays of laterally ordered nanochannels interconnected to microchannels of tunable size, over large surface areas, is disclosed. The method incorporates DNA combing and subsequent imprinting. Associated micro and macroscale inlets and outlets can be formed in the same process or manufactured later in low cost, non-cleanroom techniques. The techniques embrace two procedures, generating DNA nanostrands and translating these strands into nanoscale constructs via imprinting. Devices incorporating the novel arrays have a first microchannel, a second microchannel and a nanochannel that is substantially linear and which defines an axis. The nanochannel is connected at its open ends to the microchannels, which are aligned along the axis. Methods for precise dose delivery of agents into cells employing the devices in nanoelectroporation methods are also disclosed.
