“…One may keep in mind that the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) levels of the OSC should not allow electrolyte oxidation or reduction; another very important parameter is that the electrolyte should not penetrate into the OSC, which would become electroactive. Even though Buth et al used α-sexithiophene (α6T) in 2011 and 2012 to make an EGOFET-based biosensor [11,62], most EGOFET biosensors were reported with poly(3-hexylthiophene) (P3HT) as the organic semiconductors [8,32,60,[63][64][65][66][67][68][69][70][71][72]. In recent years, thienothiophene copolymers [73], especially the poly(2,5-bis(3-alkylthiophen-2-yl)thieno[3,2-b]-thiophene) (pBTTT) was also considered, due to a better stability in humid environment or even in water ( Figure 4) [74][75][76][77].…”

Electrolytic Gated Organic Field-Effect Transistors for Application in Biosensors—A Review

Electrolyte-gated organic field-effect transistors have emerged in the field of biosensors over the last five years, due to their attractive simplicity and high sensitivity to interfacial changes, both on the gate/electrolyte and semiconductor/electrolyte interfaces, where a target-specific bioreceptor can be immobilized. This article reviews the recent literature concerning biosensing with such transistors, gives clues to understanding the basic principles under which electrolyte-gated organic field-effect transistors work, and details the transduction mechanisms that were investigated to convert a receptor/target association into a change in drain current.
