In this report, we demonstrate a hand-held wireless voltage-clamp amplifier for current measurement of nanopore sensors. This amplifier interfaces a sensing probe and connects wirelessly with a computer or smartphone for the required stimulus input, data processing, and storage. To test the proposed signal transduction by ion nanogating (STING) wireless amplifier, in the current study the system was tested with a nano-pH sensor to measure pH of standard buffer solutions and the performance was compared against the commercial voltage-clamp amplifier. To the best of our knowledge, STING amplifier is the first miniaturized wireless voltage-clamp platform operated with a customized smart phone application (app).
