Fig. 20 (a) SEM images of the pillars of the azobenzene CLCP microarray before (left) and
after (right) UV irradiation. (b) Schematic illustration showing the change in the geometry of the
pillars of the azobenzene CLCP microarray. (c) Reflection spectra of the azobenzene CLCP
microarray under the UV light irradiation (365 nm, 20 mW cm
