Fluorescent Sensors for Measuring Metal Ions in Living …
Because many metal sensors involve a change in brightness upon metal binding, we report brightness in the metal-free and metal-bound state. However, there may be differences in the photophysical properties of a sensor in vitro (i.e., in a cuvette) versus in situ (i.e., inside a cell) due to differences in viscosity, pH, solvent, accessibility to oxygen, or other factors associated with the
