General spectroscopic analyses in electromagnetic radiation give accurate qualitative/quantitative data. The issues regarding real-time analyses have not shown a possible solution so far with these classical analyses. As a novel solution to the problems, we propose a prototype of an intelligent chemical sensor system capable of simultaneous measurement for Spectro/Gravimetric variables. Two platforms were designed based on reflection mode and transmission mode, and the platforms were demonstrated through Electroluminescence measurements of conductive polymer film and sensing of metal ions.
A reflection-mode of platform composed of QCM and si photodiode, measured Electroluminescence by electro-polymerization of Polypyrrole and Cyclic voltammetry(CV). Our developments can provide the understandings for dynamic Spectro/Electro/Gravimetric changes during CVs, investigate analytical relations among the electroluminescence, current density, mass change, and viscoelasticity changes of the films.
The transmission-mode platform was constructed using ITO and si photodiode. To enhance the stability of the ITO electrode, Na+ doping was performed, and the results were verified through impedance analyzer, contact angle, UV/vis, and Quartz crystal analyzer. Furthermore, to improve selectivity and sensitivity in sensing, a Layer-by-Layer (LBL) process was carried out with Poly (vinyl sulfate) potassium salt (PVSK) and toluidine blue O solution (OTB). We Demonstrated the capability of qualitative and quantitative analysis on the platform, sensing of Al3+ based on concentration and sensing of di-and trivalent metal ion as Cd2+, Cr3+, Cu2+, Fe3+, Ni3+, Pb2+, Sn2+, Zn2+.
