초록
용존산소농도(DO)와 pH를 동시에 검출하기 위하여 이중층 광학 센서 막을 제조하였다. DO 민감성 염료인 Rudpp를 MTMS 졸-겔에 혼합하고 24-웰 마이크로타이터 플레이트에 코팅하였다. DO-검출층 위에 HPTS와 혼합된 GA 졸-겔 용액을 코팅하고 pH 측정을 위해 사용하였다. 이중층 광학 센서 막은 온도와 이온 강도에 영향을 받았다. 또한 DO와 pH 이중층 광학 센서 막은 미생물발효공정에 온라인 모니터링 하는데 응용하였으며 좋은 성능을 보였다.
A double-layer optical sensing membrane has been fabricated to measure the concentration of dissolved oxygen (DO) and pH value simultaneously. (tris(4,7-diphenyl-1,10-phenanthroline (Rudpp) ruthenium(II)) as a DO sensitive dye has been mixed in the methyl trimethoxy silane (MTMS) sol-gel solution and coated onto one well in a 24-well microtiter plate. On the DO-sensing layer the GA (3-glycidoxypropyl trimethoxy silane (GPTMS), 3-aminopropyl trimethoxy silane (APTMS)) sol-gel solution mixed with 8-hydroxypyrene-1,3,6-trisulfonic acid trisodium salt (HPTS) has been coated and used to measure pH values. The double-layer sensing membrane was affected by ionic strength and temperature. The double-layer sensing membrane for DO and pH has been applied to online monitor in microorganism cultivation processes and showed a good performance.
