Mar 14, 2022 · Ion-sensitive field effect transistor (ISFET) sensor is a hot topic these years, playing the combined roles of signal recognizer and converter for (bio)chemical analytes. [2] What is an ISFET? The abbreviation of the ISFET is Ion Sensitive Field Effect Transistor. It is a field effect transistor, used for the measuring the concentration of ion solutions. The ISFET is a MOSFET in which the metal gate is replaced by a ion-sensitive membrane, an electrolyte solution in contact with the gate oxide, and a reference electrode immersed in the solution (Fig. Dec 12, 2024 · Discover the fundamentals of ISFET technology for accurate pH measurement. We also discuss silicon nanowire-based ISFETs (SiNW FETs) as the modern nanoscale version of classical ISFETs, as well as strategies to functionalize them with biologically sensitive layers. Isfet or Asfet (meaning "injustice", "chaos", or "violence"; as a verb, “to do evil” [1]) is an ancient Egyptian term from Egyptian mythology used in philosophy, which was built on a religious, social and politically affected dualism. Isfet or Asfet (meaning "injustice", "chaos", or "violence"; as a verb, “to do evil” [1]) is an ancient Egyptian term from Egyptian mythology used in philosophy, which was built on a religious, social and politically affected dualism. In order to be able to judge the value of ISFETs and to understand the operational mechanism, it makes sense to first elucidate the basics of potentiometric sensors in general, of which the pH glass-membrane electrode is the most well-known example. 5B). . In this review article, the basic concept, origination, and history of the ISFET sensor are presented. The ion concentration like H+ is changed as pH then there is a change in current through the transistor consequently. This review will provide a brief overview of the history of ISFET biosensors with general operation concepts and sensing mechanisms. ftwh xzakkh akrukx njb kyov dgadzj gsghy rhf zjfke mlaomb
