TL;DR: In this paper, a field effect transistor for detecting ionic material was proposed, which includes a substrate formed of a semiconductor material, a source region and a drain region spaced apart from each other in the substrate and doped with an opposite conductivity type to that of the substrate, an insulating layer disposed on the channel region and formed of an electrically insulating material.

TL;DR: By directly reading the negative charges of DNA molecules, DNA concentrations from 1 muM to 10 muM have been successfully discriminated and non-surface-binding detection technique allows to quantify DNA molecules continuously and sequentially and to reuse the sensor by simple washing protocol.

TL;DR: In this paper, a method of manufacturing a nanosensor may include forming a first insulating layer, graphene, and a metal layer on a substrate, patterning the metal layer and the graphene, forming a protective layer on the portion of the graphene and the metal layers, exposing the graphene by removing a portion of an exposed layer, and forming a hole in the substrate, and connecting the graphene to the hole.

TL;DR: In this paper, the surface of a gate of an FET sensor with a ligand that can bind to a side of a nucleic acid was used to increase the debye length.
