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 ...

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 ...

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 ...

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 ...

(Nanowerk Spotlight) Ion-transport-based sensory systems can be categorized into three groups – ionic sensors, ionic processors, and ionic interfaces – all of which center on ion transport. The ...

What are Organic Field-Effect Transistors? Organic field-effect transistors (OFETs) are a type of transistor that uses an organic semiconductor material as the active layer. Unlike conventional ...

With the right mix of materials, TFETs promise cooler, smaller, and more efficient circuits for everything from the Internet of Things to brain-inspired computers. But before they can leave the lab, ...

A graphene layer consists of carbon atoms linked by covalent bonds, forming a honeycomb structure. Its excellent electron mobility, chemical and physical stability, electrical and thermal conductivity ...
