Figure 5
Intensity distribution within the PEG microgel (a) and PNIPAM brush (b) as a function of the scattering depth at the selected incident angles from Fig. 4: the solid lines at = 0.35° and = 0.2°, respectively, correspond to the evanescent wave intensity at scattering depth < 0; the dotted lines at = 1.0° correspond to the transmitted signal. Blue, cyan and black blocks illustrate intensity at different scattering depth ranges (blue: 0–20 nm, cyan: 20–50 nm, black: >50 nm). The gray color region indicates the Si block. |
