Abstract:

Recognition of specific biomolecules such as a unique proteins in biological cells is critical for basic biomedical research and the development of novel clinical diagnostics. Considerable interests exist in searching for the novel fluorescent probes that can target specific biological tissues/molecules to meet the need for advanced bioimaging. For in vivo tracking of a specific type of biomolecule or tissue, the probes are also required to be non-toxic, and their presence should not disturb the normal biological development process. In the presentation, we discuss a new class of fluorescent imaging dyes, which are typically non-fluorescent in an aqueous environment. The probes, however become highly fluorescent upon binding to biomolecules such as proteins. The binding-activated fluorescence on biomolecules can be further developed to give wash-free imaging reagents, as those free probes are nearly non-fluorescent in the surrounding aqueous environments. Further extending this concept has led to advanced imaging reagents, which selectively targets the biomolecules in the subunits of biological cells, e.g. organelles, to give fluorescence turn on.
