In the present research, development of adsorption based sensing system of hazardous micro-pollutant in water environment using stimuli-responsive hydrogel-quartz crystal microbalance conjugate was performed. The system applied the self-regulating phase behavior/property of the gel as the principal mechanism of the sensing. Basic property of QCM that was conjugated with the cross-linked stimuli-responsive adsorbent hydrogel was examined. The use of network analyzer with big power supply was found to enable the application of the gel with large molecular weight in the sensing with keeping high resolution of QCM. The new method to identify the phase behavior of hydrogel during environmental change with high resolution was also developed by using a technique of inert liquid film sealing of gel The sensing system based on the stimuli-responsive hydrogel-QCM-A conjugate was developed.

在本研究中，采用刺激响应型水凝胶-石英晶体微天平共轭物，开发了基于吸附的水环境中有害微污染物传感系统。该系统将凝胶的自调节相行为/特性作为传感的主要机制。考察了与交联刺激反应吸附水凝胶偶联的QCM的基本性质。采用大电源的网络分析仪，可以使大分子量凝胶应用于QCM的检测中，并保持高分辨率。利用凝胶的惰性液膜密封技术，开发了一种高分辨率识别水凝胶在环境变化过程中相行为的新方法。
