Abstract
In this research the electromagnetic interaction of a novel planar interdigital sensors with chemicals contaminated in seafood has been studied. A planar interdigital sensor based sensing system has been fabricated for assessment of seafood quality. Our main objective is to sense the molecule of Domoic Acid presence in mussels. Three peptide derivatives namely Sarcosine, Proline and Hydroxylproline were used for the initial studies which are structurally closely related to our target molecule. The proline molecule is arguably the most importantamino acid in peptide conformation, contains the basic structural similarity to the domoic acid. Three novel interdigital sensors have been designed and fabricated. The initial result shows thatsensors respond very well to the chemicals and it is possible to discriminate the different chemicals from the output of thesensor. Results from the analysis have shown that Sensor-1 has etter sensitivity compared to other sensors. Sensor-1 was chosen for further analysis with real mussels. The changes in sensor impedance were then analysed with real mussels before and after adding the proline. The presence of proline on the mussel samples was detected by the sensor. Results also shown that a good correlation of R 2 = 0.717 between sensitivity with sample
