Formation of a gold nanoparticle-polyamide nanohybrid by using reverse micelles and its spectroscopic characterization

本文首次研究了在水溶液和反胶束溶液中制备均匀金纳米粒子的快速方法。然后，开发了一种结合流动系统的仪器，用于原位显微测量。在流动池的玻璃表面，利用反胶束吸附作为微反应器，通过界面聚合制备了聚酰胺的纳米结构。通过将金纳米粒子固定在聚酰胺纳米结构上，可以简单地形成金-聚酰胺纳米杂化物。采用光散射、荧光显微镜和原子力显微镜观察了聚酰胺纳米结构和纳米杂化材料的形成。为了开发基于金聚酰胺纳米杂化材料的新型传感器，目前正在进行纳米杂化材料的光谱表征工作。

A rapid method for preparing uniform gold nanoparticles in aqueous and reversed micellar solutions has been first examined. Then, an instrument combined with a flow system was developed for in situ microscopic measurements. On glass surfaces of the flow cell, the nanostructure of polyamide was produced by the interfacial polymerization using reverse micelles adsorbed as microreactors. By immobilization of Au nanoparticles on the polyamide nanostructure, the Au-polyamide nanohybrid was formed simply. Light scattering and fluorescence microscopic measurements and atomic force microscope measurements were carried out to observe the formations of the polyamide nanostructure and the nanohybrid. For the purpose of development of novel sensors based on the Au-polyamide nanohybrid, work is now in progress on spectroscopic characterization of the nanohybrid.
