Ion bipolar junction transistors [PDF]

open access: yesProceedings of the National Academy of Sciences, 2010
Dynamic control of chemical microenvironments is essential for continued development in numerous fields of life sciences. Such control could be achieved with active chemical circuits for delivery of ions and biomolecules. As the basis for such circuitry, we report a solid-state ion bipolar junction transistor (IBJT) based on conducting polymers and ...
