They coated these transistors with breast cancer cells and then added an antibody linked to a chemical reporter that causes a change in pH if the antibody recognizes the cells. The results of membrane ...

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 ...
