Figure 5
Cross section of a gold cross fluorescence map with (from top to bottom) 1 µm, 2 µm and 5 µm cell size, showing the experimental (blue dots) fluorescence profile and fitted overlap model (red curve). The horizontal slices on the left panel correspond to the dashed blue lines on the fluorescence maps on the right panel. Framed inset (top right), schematic of the overlap model used for modeling the experimental signal: convolution of the 3 µm-wide cross shape and the 5 µm FWHM Gaussian beam. |
