ORGANIC FIELD -EFFECT TRANSISTOR SENSOR

摘要

Transistor comprising at least one conductive layer (4), at least one gate dielectric layer (3) and at least one semiconducting film (1) deposited on top of a receptor molecule layer (2) previously deposited or covalently linked to the surface of the gate dielectric (3). Said layer of biological material is constituted by single or double layers of phospholipids, layers made of proteins such as receptors, antibodies, ionic channels and enzymes, single or double layers of phospholipids with inclusion or anchoring of proteins such as: receptors, antibodies, ionic channels and enzymes, layers made of oligonucleotide (DNA, RNA, PNA) probes, layers made of cells or viruses, layers made of synthetic receptors for example molecules or macromolecules similar to biological receptors for properties, reactivity or steric aspects.
