| Research Abstract |
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.
