Nanohybrids Near-Field Optical Microscopy: From Image Shift to Biosensor Application

Figure 7

(a) Topographic and (b) optical scattering and (c) fluorescence near-field images of hybrid aggregates. The blue arrow shows the region for which shift analysis was done. The difference between scattering and fluorescence imaging is clear, as much more noise is detected in the first case than in the second.
