| Summary: | 博士 === 國立中興大學 === 化學系所 === 96 === This topic was focused on the electrodes have those advantages of mass produced, lower cost, convenient, and disposable electrode coated with Ni by barrel plating technology. Because the electrodes coated by high-cost metal material has good specific and catalytic ability in general, its high cost due to be hardly to apply the disposable electrode like screen printed electrode. According to this point, we applied activated nickel
material for bio-analysis, heavy metal assay, and pathology research on this electrode. And it also integrated into specific flow cell for flow injection
analysis and high performance liquid chromatography, let the assembled operation of detector be briefer. It is easier to achieve better convenience and reproduction for electro-analysis.
There were four main applications for nickel barrel plating electrode (Ni-BPE) after electro-method activation. One is the strong oxidative of Ni-BPE for different steric structure of monosaccharide without using
enzyme in alkaline solution; two, using the delicate response of glucose as carrier solution in flow injection analysis is the steady oxidative current by Ni-BPE, and the oxidative signal will be inhibited by diverse concentration of phosphate anion; three, Ni-BPE was coupled with high performance liquid chromatography (HPLC) for the assays of chromium(III) of amphoteric element, oxalic acid metabolism precursors, antibiotics, the
chemical with amino functional group, cosmetic, and formaldehyde; four, electrochrmoic between Ni(III) and Ni(II) by potential setting was blocked from specific amino acid and protein, and it can be used for His-tagged
technology in the future.
