Abstract

In this study, we explore the relation between near-field and far-field characteristics of plasmon-enhanced total internal reflection fluorescence (TIRF) imaging. It was found that a significant disparity exists between near-field intensity maximum of evanescent fields and reflectance minimum in the far-field. The disparity tends to be larger when plasmons are localized by surface nanostructures. Experimental data with nanogratings and nanoislands as well as theoretical results are presented. The disparity can be considered to optimize plasmon-enhanced TIRF microscopy.
