A naphthalimide based fluorescent probe for imaging microviscosity in living cells
首发时间:2017-04-28
Abstract:Intracellular viscosity strongly influences transportation of mass and signal, interactions between the biomacromolecules and diffusion of reactive metabolites in live cells. Herein, we developed a naphthalimide-hemicyanine based fluorescent probe Cyt-NA for imaging the change of microviscosity in living cells. Cyt-NA exhibited about 260 folds fluorescence increasing at 610 nm along with the increasing viscosity from 1.0 cP to 1410 cP. These satisfying response properties make Cyt-NA possible to monitor viscosity changes under starvation and low temperature conditions, offering us more practical information about microenviromental viscosity in living cells.
