Abstract

A novel planar interdigital sensor based sensing and instrumentation system has been developed for detection of dangerous contaminated chemicals in seafood. Three novel interdigital sensors have been designed and fabricated. The sensors were designed with different configurations and analyses of all sensors were conducted from the experiments in order to select the best sensor for further analysis with domoic acid. Initial studies were conducted with Proline which is structurally close related to our target molecule, domoic acid. The changes in sensor sensitivity were analysed with mussels before and after adding the proline. The presence of proline on the mussel surface and also inside the mussel was very clearly detected by the sensor. Further experiment was conducted with small amount of domoic acid (0.5 μg to 5.0 μg) and it was found that Sensor-1 was able to detect approximately 12.6 μg/g of DA in mussel meat. Results of the effect of water and different concentration of domoic acid were also carried out and presented. Threshold levels of sensor's sensitivity with different mussel thickness were established. The outcomes from the experiments have shown that novel interdigital sensing system has the potential to be one of the options to assess the quality of seafood products for in-situ monitoring.
