  • Patent number: 9671360
    Abstract: Disclosed is a method for manufacturing a biosensor comprising (a) forming an insulating layer in an electrode region; (b) coating the first photoresist layer on the insulating layer; (c) performing the first exposing process on the first electrode region through the first photomask; (d) removing unexposed area of the first photoresist layer except for the first electrode region using development; (e) coating the second photoresist layer on the first electrode region and the insulating layer after the step (d); (f) performing the second exposing process on the second electrode regions through the second photomask; (g) performing the third exposing process on the top portion of the second photoresist layer through a photomask with open areas in the shape of micro-sized wires connecting the second electrode regions; (h) removing the second photoresist layer except for the portions exposed in the steps (c), (f) and (g) using development.

  • Patent number: 9513555
    Abstract: The present invention provides a method for manufacturing a suspended single carbon nanowire and piled nano-electrode pairs, and a suspended single carbon nanowire and piled nano-electrode pairs manufactured using said method. A suspended single carbon nanowire, which is manufactured at a high yield by the method for manufacturing a suspended single carbon nanowire according to the present invention, has a minimized dimension, and a suspended carbon nanomesh, which is manufactured at a high yield by the method for manufacturing piled nano-electrode pairs according to the present invention, is thin and dense. The present invention also provides a gas sensor or an electrochemical sensor, to which a suspended single carbon nanowire and piled nano-electrode pairs manufactured by the method according to the present invention are applied.
