fabrication 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...
Potassium Ion-Sensitive Field Effect Transistor
was readily constructed by simple modification of a common FID hydrocarbon monitor, with addition of a commercially available valve oven, switching valve, and timer. This system, except for the adjusted response time, had virtually the same operating specifications as the original hydrocarbon analyzer. Short-term studies indicated the system was practical, reliable, and accurate. Air-monitoring...
متن کاملFlow injection analysis of paracetamol using a biomimetic sensor as a sensitive and selective amperometric detector
This work describes the coupling of a biomimetic sensor to a flow injection system for the sensitive determination of paracetamol. The sensor was prepared as previously described in the literature (M. D. P. T. Sotomayor, A. Sigoli, M. R. V. Lanza, A. A. Tanaka and L. T. Kubota, J. Braz. Chem. Soc., 2008, 19, 734) by modifying a glassy carbon electrode surface with a Nafion membrane doped with i...
متن کاملIon 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 کاملA new era of semiconductor genetics using ion-sensitive field-effect transistors: the gene-sensitive integrated cell.
Semiconductor genetics is now disrupting the field of healthcare owing to the rapid parallelization and scaling of DNA sensing using ion-sensitive field-effect transistors (ISFETs) fabricated using commercial complementary metal -oxide semiconductor technology. The enabling concept of DNA reaction monitoring introduced by Toumazou has made this a reality and we are now seeing relentless scaling...
