Quantum dots （QDs） attracted tremendous attentions in the past two decades because of their high emis- sion quantum yields, good chemical and photo - stability, size - tunable emission profiles and narrow spectral bands in comparison with conventional organic fluorophores. Recently, the great advances in the surface chemistry of QDs made them get wide practical applications, such as ions probes area. The new development of QDs ion - probe in bio - analyti- cal chemistry by introducing the reaction mechanism between QDs and ions and their applications were focused on. Two aspects of inorganic ions and H ~ probes were reviewed. The tendency of ions probe in bio - analytical chemistry was also discussed.
