The perturbation… … of glucose uptake in organisms is an essential barometer in various metabolic diseases. In their Full Paper on page 143 ff. S. B. Park et al. report on a novel fluorescent glucose bioprobe that can translocate into cytoplasm by glucose-specific transport systems through the competition with D-glucose. Unlike reported glucose bioprobes, such as NBDGs and 2-deoxyglucoses, this fluorescent glucose bioprobe allows the real-time and quantitative measurement of glucose uptake in living cells.
