Preparation offunctional interface and its in situ measurement

我们开发了一种利用聚合物微通道制备功能表面的方法。该方法的优点如下：1)利用聚酯原位聚合的新型玻璃模板制备了可重复的聚合物微通道。2)通过在不饱和聚酯中加入分子内带有双键的功能分子，分子功能很容易被纳入微通道。3)通过微通道内壁的进一步衍生化，开发了一种功能表面的制备技术。关于实际效果，请参考发表在学术期刊上的论文。然后我们开发了一种新型的“全内反射几何热透镜光谱法”。该方法可实现固液界面的精确分析。我们将该方法应用于玻璃/液界面，探测溶解于液相中的有机染料。首次明确了染料的吸附行为、吸附速度和吸附机理。然后，我们将该方法应用于液/液界面，以了解络合物的形成机理。同时针对高分辨率热显微镜，我们开发了扫描热透镜显微镜。该研究在传统显微镜的基础上增加了许多可能性，扩大了热透镜光谱的研究范围。我们期待这项技术为材料科学、生物学研究开辟新的研究领域。我们在玻璃表面做了一个微型图案。然后显微镜对样品和光束进行x、y扫描成像。显微镜的分辨率约为50微米。使用光束扩展器使分辨率比原始仪器设置的分辨率高5倍。

We have developed a preparation method for functional surface utilizing polymer micro channel. The merits of the method are as follows: 1) We have developed reproducible polymer micro channel using a novel glass template with in situ polymerization of polyester. 2) Molecular function was easily incorporated into the micro channel by the addition of functional molecule with double bond inside the molecule to the unsaturated polyester. 3) Also we have developed a preparation technique of functional surface by the further derivatization of inner wall of the micro channel. Regarding to the practical results, please refer to the papers published in the Academic Journals.Then we have developed a novel 'Thermal Lens spectrometry with total internal reflection geometry'. The method enables precise analysis for solid-liquid interface. We apply this method to the glass/liquid interface to probe organic dye dissolved in liquid phase. We first made the adsorption behavior, adsorption velocity, and adsorption mechanism of the dye clear. Then we applied this method to liquid/liquid interface to understand the mechanism of complex formation. And also aiming at the high-resolution thermal microscope, we have developed scanning thermal lens microscope. This study has many possibilities over conventional microscope and enlarges the scope of the thermal lens spectroscopy. We expect that this technique pioneer the new research field for the material science, biological studies. We made a micro pattern on a glass surface. Then the microscope imaged the pattern by x, y - scanning of the sample and beam. The resolution of the microscope was about 50 micrometer. Use of a beam expander made the resolution 5 times greater than the one for original instrumental setup.
