A Verilog-A-based Redox-Signal Transduction Model for Co-Simulating Surface-Bound Electrochemical Biosensors and Circuits

Wei Foo

2025

Surface-bound electrochemical aptamer-based (E-AB) sensors are a promising approach for continuous in-vivo and in-vitro biomolecular monitoring because they offer high selectivity, sensitivity, and real-time detection. However, accurately co-simulating E-AB sensors with readout circuits remains challenging due to the redox reporter’s position-dependent electron-transfer kinetics and the electrical double layer’s (EDL) complex behavior at the electrode-electrolyte interface. Here, we present a compact, SPICE-compatible electrochemical cell model that combines a Verilog-A...
