Multiplexing System for Automated Characterization of a Capacitive Field‐Effect Sensor Array

In comparison to single‐analyte devices, multiplexed systems for a multianalyte detection offer a reduced assay time and sample volume, low cost, and high throughput. Herein, a multiplexing platform for an automated quasi‐simultaneous characterization of multiple (up to 16) capacitive field‐effect sensors by the capacitive–voltage (C–V) and the constant‐capacitance (ConCap) mode is presented. The sensors are mounted in a newly designed multicell arrangement with one common reference electrode and are electrically connected to the impedance analyzer via the base station. A Python script for the automated characterization of the sensors executes the user‐defined measurement protocol. The developed multiplexing system is tested for pH measurements and the label‐free detection of ligand‐stabilized, charged gold nanoparticles.
