Researchers have found that a system based on ion-sensitive field effect transistors -- a tiny electrical circuit that is activated by a change in pH -- and enzymatic chemical signal amplification can ...

In 1947, Shockley, Brattain and Bardeen were investigating the field effect transistor but lead them into inventing the bipolar transistor instead. In 1952, the field effect transistor of Shockley was ...

Accurately measuring small shifts in biological markers, like proteins and neurotransmitters, or harmful chemicals in the water supply, can identify critical problems before they have a chance to ...

WASHINGTON, December 21, 2021 -- Demand for sensitive and selective electronic biosensors -- analytical devices that monitor a target of interest in real time -- is growing for a wide range of ...

The formula for a perovskite compound is typically expressed as ABX3. These are crystalline structures that bond two cations ("A" and "B", divalent metal ion) to an anion ("X"); the "B" atoms tend to ...

Researchers from Tokyo Medical and Dental University (TMDU) find that ion-sensitive field effect transistors can be combined with enzymatic chemical signal amplification to detect a cancer-related ...
