dc.description.abstract | A disposable solid-state pH sensor was realized by utilizing two nanoporous Pt (npPt) electrodes and a copolyelectrolytic junction One nanoporous Pt electrode was to measure the pH as an indicating electrode (pH-IE) and the other assembled with copolyelectrolytic junction was to maintain constant open circuit potential (E(oc)) as a solid-state reference electrode (SSRE) The copolyelectrolytic Junction was composed of cationic and anionic polymers immobilized by photo-polymerization of N,N`-methylenebisacrylamide, making buffered electrolytic environment on the SSRE It was expected to make The nanoporous Pt surrounded by a constant pH excellently worked as a solid state reference electrode so as to stabilize the system within 30 s and retain the electrochemical environment regardless of unknown sample solutions Combination between the SSRE and the pH-IE commonly based on nanoporous Pt yielded a complete solid-state pH sensor that requires no internal filling solution The solid state pH sensing chip is simple and easy to fabricate so that it could be practically used for disposable purposes Moreover the solid-state pH sensor successfully functions in calibration-free mode in a variety of buffers and surfactant samples | ko_KR |
