英文摘要: Photometry is widely used for trace analysis in life science, food safety and environmental monitoring, owning to its fast speed analysis and ease of use. This project will investigate the novel nonlinear optical-path enhancement effect in metal-waveguide-capillary (MWC), which can break the restriction of physical length on optical-path. Thus, enhancing the detection sensitivity and resolving the problems of gas bubble trapping and light leaking can be realized. In addition, investigation on combination of Au nano-particles and MWC will be carried out for observing the novel LSPR effects and realizing high sensitive detection of molecule absorption process. Finally, a portable photometry with high sensitive, high selective and ease of use would be realized.
