Connecting of LSPR sensor with different analytical methods in a compact device has challenges to obtain simultaneous sensing of several properties. In this study aimed is to develop an integration LSPR-EIS device onto a single sensor based on glass substrate for aqueous detection. The LSPR-EIS sensor was fabricated on glass substrate. The EIS sensor utilize a gold (Au)-interdigitated electrode (IDE) which conducted by using vacuum thermal evaporation technique and wet etching. Then, the Au-IDE was annealed at 400 °C to create gold nanoparticles (AuNPs) on the surface of Au-IDE structure. The measurement results open up strongly high promising to combining LSPR-EIS sensor in one chip for aqueous detection.
