Comparison of interfacial fluorescence images on the AuOA sheet and on glass. (a) Schematic drawing of the depth of the LSPR and evanescent fields on the AuOA and glass surface, respectively. (b) Fluorescence images of PE-labeled actin filaments in RBL-2H3 cells in aqueous media. The incubation time for the cell adhesion was overnight. The incident light was 561 nm in wavelength, and the intensity was 5 mW. The incident angle was 67° at a critical TIR angle of 61.7°. The exposure time was 30.5 msec (left) or 500 msec (right).
