项目摘要

In order to develop a novel artificial electronic nose (e-NOSE) system, first of all, we tried to do the functional design of chemical sensors such as quartz crystal microbalance (QCM) sensor, surface plasmon resonance (SPR) sensor and metal oxide semiconductor (MOS) sensor. Then, we also tried to prepare such chemical sensors based on the thin film fabrication technologies of organic and inorganic materials using plasma, which can use as sensing membrane of e-NOSE. Furthermore, we examined the application of fabricated chemical sensors. The following results are obtained :(1) It was found that the QCM odor sensor response for various gases strongly depended on the functional group of molecular recognition membrane. This is very important to prepare the QCM odor sensor with excellent selectivity.(2) We developed a unique fabrication technique using plasma chemical vapor deposition which can polymerize the organic thin film as molecular recognition membrane for QCM and SPR chemical sensors.(3) We developed a novel SPR odor sensor with molecular recognition membrane, which can use as one of useful sensor for e-Nose system.(4) It was found that the magnetron sputtering technique is very useful for MOS thin film gas sensors having high sensitivity for many gases and for integration of MOS gas sensor array.(5) It was found that quality of Japanese sake and vinegar can be estimated using developed QCM, SPR and MOS chemical sensors.In order to develop intelligent e-NOSE system which can characterize the chemical component of gas mixture and many kinds of smell we are now working on QCM, SPR and MOS sensor in conjunction with pattern recognition analysis.

为了研制新型的人工电子鼻系统，首先对石英晶体微天平（QCM）传感器、表面等离子体共振（SPR）传感器和金属氧化物半导体（MOS）传感器等化学传感器进行了功能设计。然后，我们还尝试了基于等离子体的有机和无机材料的薄膜制备技术来制备这样的化学传感器，其可以用作e-NOSE的传感膜。此外，我们研究了制造的化学传感器的应用。结果表明：（1）QCM气味传感器对各种气体的响应强烈依赖于分子识别膜的官能团。这对制备具有良好选择性的QCM气味传感器具有重要意义。(2)我们发展了一种独特的等离子体化学气相沉积技术，可以将有机薄膜作为QCM和SPR化学传感器的分子识别膜。(3)我们研制了一种新型的带有分子识别膜的SPR气味传感器，它可以作为电子鼻系统的有用传感器之一。(4)结果表明，磁控溅射技术对于制备对多种气体具有高灵敏度的MOS薄膜气敏元件和集成MOS气敏元件阵列是非常有用的。(5)研究发现，QCM、SPR和MOS化学传感器可以用于日本清酒和醋的质量评价，为了开发能够表征气体混合物化学成分和多种气味的智能e-NOSE系统，我们正在将QCM、SPR和MOS传感器与模式识别分析相结合。
