"photonic metasurfaces that operate visible range biomedical applications... deliver complex information... images immediately interpreted... integrating different photonic into one device... holographic metasurfaces encode more than one image... meta-atoms act like pixels... reflects light of specific wavelength in dry conditions... high reflectivity when different wavelength used in wet conditions... refractive index of the surrounding medium as an additional degree of freedom"
