Modelling of an interdigital sensor-based sensing system for the detection of dangerous contaminated marine biotoxin in seafood has been carried out. Three interdigital sensors having new electrode configurations have been analysed using COMSOL Multiphysics. All sensors were designed to have an equal number of electrodes with the same sensing area. Based on the maximum sensitivity, the best electrode configuration has been chosen. Experiments on raw seafood contaminated with domoic acid have been conducted using the new fabricated sensor and very good results were obtained.
