A biological device comprising a substrate, a gate electrode, and a sensing well. The substrate includes a source region, a drain region, a channel region, a body region, and a sensing region. The channel area is set between the source area and the drain area. The sensing area is disposed at least between the channel area and the body area. The gate electrode is disposed at least on or above the channel region of the substrate. The sensing well is disposed at least adjacent to the sensing area. |
