  • Patent number: 11426728
    Abstract: An electroporation device is disclosed, which includes a first tubular electrode including a first inlet and a first outlet; an aqueous solution supply connected to the first tubular electrode and configured for supplying an aqueous solution to the first tubular electrode and for allowing a droplet of the aqueous solution to be discharged from the first outlet of the first tubular electrode, the aqueous solution contains a cell and a delivery target substance; a second tubular electrode including a second inlet and a second outlet, wherein the second inlet is spaced away from the first outlet at a spacing corresponding to a size of a portion of the droplet; a power supply for applying a voltage to the electrodes for electroporation of the cell in the droplet; and a droplet sucking unit connected to the second electrode and configured for allowing the droplet to be sucked into the second electrode.

  • Patent number: 11201198
    Abstract: Display devices and, in particular, electroluminescent display devices including a lower structure of a bank causing a highly conductive hole injection layer to take on a shape so as to reduce a leakage current, and a method for manufacturing the same are described. An electroluminescent display device includes a substrate having a plurality of pixels, a bank located at a boundary between the subpixels, a first electrode in each subpixel, a separation induction layer between the bank and the first electrode, a p-type layer with a first portion on the bank and a second portion on an emission assembly of the subpixels, and at least one common layer on the p-type layer.
