“…However, the operation of a single-ended potentiostat is limited by the swing of the control amplifier for lowsupply voltage chip applications and can be affected by common-mode interference. In order to adapt to various scenarios and solve the problem of small output swing of single-ended potentiostats in low-voltage applications, Ghodsevali et al [56] and Martin et al [57] proposed the potentiostat with a fully differential structure, as shown in Fig. 3.…”

Electrochemical detection is widely used in biosensing fields, such as medical diagnosis and health monitoring due to its real-time response and high accuracy. Both passive and active electrodes and the corresponding readout circuits have been continuously improved over the past decades. This article summarizes the redox reaction method, state-of-the-art electrode materials, and readout circuits based on the passive three-electrode. The redox-current-based readout circuits are widely used and developed toward multichannel high precision and low power consumption. In terms of active electrodes, this article reviews the development of field-effect transistors (FETs)-based electrochemical detection and readout circuits. In the past decade, the development of organic electrochemical transistors (OECTs) has also enabled more precise electrochemical detection.INDEX TERMS Ion-selective field-effect transistor (ISFET), organic electrochemical transistor (OECT), potentiostat, three-electrode system, transimpedance amplifier (TIA).

We present a four-channel, high-sensitivity and linearity electrochemical biosensor for neurotransmitter (NT) detection and measurement. Using a multi-channel microfluidic platform makes this biosensor capable of detecting NT-related currents going from nanoamperes to milliamperes, with a sensitivity of the order of picoamperes. Moreover, by using a fully differential potentiostat architecture, the biosensor offers a high common-mode rejection ratio (90 dB), making it appropriate for low-noise and high-sensitive applications. The system was implemented on a 15 mm × 15 mm PCB with direct interface to the microfluidic chambers. It was calibrated with a 5 mM ferrocyanide solution and successfully tested with dopamine at three concentrations. The system shows a minimum sensistivity of 100 pA and consumes 60 mW.
