Nanophotonics is a part of nanotechnology for investigat-ing the light-matter interactions on the nanometer scale. This field provides a new approach to achieving the limit of specificity and sensitivity in functional medical imag-ing such as photoacoustic imaging, optical coherence tomography, and two-photon microscopy. This functional imaging based on nanophotonics can expand and devel-op new diagnostic and imaging technologies towards ad-vanced healthcare technology with a nanoscale resolu-tion beyond the diffraction limit. Furthermore, functional imaging using nanophotonics has been continuously pro-gressive and expanded to other fields through the con-vergence with other available materials and platforms. This special Issue aims to introduce recent interdiscipli-nary approaches toward innovative nanophotonics-based functional imaging technologies.
