This invention provides a novel bioimaging technique that can achieve a deep observation depth and a novel method for marking a lesion that allows clear recognition of the lesion from outside a living body. This invention also provides a bioimaging marker comprising a fluorescent material obtained by doping a ceramic with rare earths and the like and a bioimaging technique comprising detecting near-infrared fluorescence that can sufficiently penetrate a living body generated upon excitation of the marker with near-infrared excitation light.
A bioimaging marker comprising a fluorescent material obtained by doping a ceramic with one or more rare earth ions and/or one or more elemental ions selected from the group consisting of uranium (U), titanium (Ti), chromium (Cr), nickel (Ni), manganese (Mn), molybdenum (Mo), rhenium (Re), and osmium (Os) ions, wherein the marker is in the form of any one of the following (a) to (c):
