    摘要: Provided is a sensing device, which includes a reactive material layer (260) responding to a specific functional group in a fluid, a sensing capacitor (B) including first and second electrodes disposed on and under an insulating layer (230), the first electrode being disposed under the reactive material layer (260), and a field effect transistor including a gate electrode connected with the first electrode of the sensing capacitor. Here, the reactive material layer (260) is formed in a conductive three-dimensional structure to widen a surface area. Thus, the sensing device may have high sensitivity by maximizing a capacitor sharing effect and a change in voltage amount applied to a gate, which may be caused by widening a surface area of the conductive three-dimensional structure with respect to the fluid flow.

    摘要: Provided are a biosensor using a silicon nanowire and a method of manufacturing the same. The silicon nanowire can be formed to have a shape, in which identical patterns are continuously repeated, to enlarge an area in which probe molecules are fixed to the silicon nanowire, thereby increasing detection sensitivity. In addition, the detection sensitivity can be easily adjusted by adjusting a gap between the identical patterns of the silicon nanowire depending on characteristics of target molecules, without adjusting a line width of the silicon nanowire in the conventional art. Further, the gap between the identical patterns of the silicon nanowire can be adjusted depending on characteristics of the target molecule to differentiate detection sensitivities, thereby simultaneously detecting various detection sensitivities.
