Unprecedentedly High Tissue Penetration Capability of Co‐Assembled Nanosystems for Two‐Photon Fluorescence Imaging In Vivo

photoreconfi gurable nanotubes, [ 10b ] fl uorescence molecular gels, [ 10c ] pH sensor, [ 10d ] heterojunction photosystems, [ 10e ] and nanorings. [ 10f ] Our and Wurthner’s groups reported NIR dyebased supramolecular adducts for fl uorescence tumor imaging in vivo. [ 13 ] Recently, we developed a series of fl uorescence J -type nanoaggregates based on bis(pyrene) (BP) molecules and successfully used them as lysosome targeted probes. [ 14 ]
