What is GEIS? When to use GEIS or PEIS?
Field-effect transistor-based biosensors have drawn attentions due to its potential for small-scale, low cost, high-throughput and sensitive devices. Applications based on Bio-FET include, but not limited to, ion sensing, detection of DNA hybridization and protein binding.
This article shows the ease of integration of the device into a system and demonstrates the range of applications of the potentiostat module by detailing three different electrochemical measurements: OCP (pH), cyclic voltammetry, and EIS.
