Ion-sensitive field effect transistor as a pH sensor.
In this work, both the static and dynamic behaviors as well as the signal read-out circuits of ISFETs were studied. The standard NMOS structure in conjunction with the insulator-electrolyte capacitor was used to model the ISFET under study. The site-binding theory was incorporated to describe the chemistry occurring at the insulator/electrolyte interface. The mechanism of the threshold voltage ...

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 کاملAn anion sensor based on an organic field effect transistor.
We propose an organic field effect transistor (OFET)-based sensor design as a new and innovative platform for anion detection. OFETs could be fabricated on low-cost plastic film substrates using printing technologies, suggesting that OFETs can potentially be applied to practical supramolecular anion sensor devices in the near future.
متن کاملIon sensitive field effect transistor modelling for multidomain simulation purposes
The proper design and simulation of modern electronic microsystems oriented towards environment monitoring requires accurate models of various ambient sensors. In particular, this paper presents a comprehensive model of an ion sensitive field effect transistor (ISFET). The model can be employed straightforwardly for simulations at device, circuit or system level. First, the model was validated ...
متن کاملIon-Sensitive Field-Effect Transistor for Biological Sensing
In recent years there has been great progress in applying FET-type biosensors for highly sensitive biological detection. Among them, the ISFET (ion-sensitive field-effect transistor) is one of the most intriguing approaches in electrical biosensing technology. Here, we review some of the main advances in this field over the past few years, explore its application prospects, and discuss the main...
