Biomolecules have been incorporated as designed planar defect layers in colloidal photonic crystals using self‐ assembly techniques (see figure). Through shifts of the photonic intragap defect mode, for example, DNA conformational changes and the enantioselective intercalation of a chiral anticancer drug can be optically monitored. This newfound capability for optically monitoring biochemistry bodes well for the development of a new generation of simple on‐the‐spot color readout biosensors.
