Ion sensitive Field Effect Transistors (ISFETs) Basics and Applications
Microfabricated semiconductor devices are essential components of many biochemical sensors today, and show great potential for advanced devices in the future. Since the proposal of an pH sensitive device, based on the technology of field effect transistors, was made in the early seventies, these so called ISFETs have been of great interest for the application in chemical and biological sensing ...
متن کاملModeling Ion Sensitive Field Effect Transistors for Biosensor Applications
During recent decades increasing interest has been shown in the development of biosensors based on ion sensitive field effect transistors (ISFETs). Many ISFET– based pH sensors have been already commercialized and attempts have also been made to commercialize ISFETbased biosensors for applications in the fields of medical, environmental, food safety, military and biotechnology areas. The growin...
متن کاملBiologically sensitive field-effect transistors: from ISFETs to NanoFETs
Biologically sensitive field-effect transistors (BioFETs) are one of the most abundant classes of electronic sensors for biomolecular detection. Most of the time these sensors are realized as classical ion-sensitive field-effect transistors (ISFETs) having non-metallized gate dielectrics facing an electrolyte solution. In ISFETs, a semiconductor material is used as the active transducer element...
متن کاملfabrication of new ion sensitive field effect transistors (isfet) based on modification of junction-fet for analysis of hydronium, potassium and hydrazinium ions
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
Deoxyribonucleic Acid Sensitive Graphene Field-Effect Transistors
We have investigated the effect of deoxyribonucleic acid (DNA) adsorption on a graphene field-effect-transistor (FET) device. We have used graphene which is grown on a Ni substrate by chemical vapour deposition. The Raman spectra of our graphene indicate its high quality, and also show that it consists of only a few layers. The current-voltage characteristics of our bare graphene strip FET show...
