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

Figure 5

(a) Representation of scheme used for the study of topographic and optical profile line shift. The green arrow represents the region for which profile line analysis was done. Topographic and optical profile lines are delimited by points A, B, and , , respectively. Points C and represent the corresponding peak signals. The optical signal is inverted downward since the detector we use has a negative polarity. (b) Comparison between topographic and optical profile lines with and without shift, as described in Section 2.1.3(B) in the text.
