Optical Property and Analytical Applications of Carbon Dots

Since their first discovery in 2004, fluorescent carbon dots (CDs) have found to be physicochemically and photochemically stable without photobleaching, making them become a star family in biosensing and bioimaging fields.More interestingly, some colorful CDs have been prepared with the same carbon source, which are similar to the optical properties of quantum dots. However, bare CDs are usually weakly fluorescent and hard to attach functional groups on the surface.Regardless continuous efforts in circumventing the problems,challenges still remain to engineer CDs with desirable biosensing and labeling properties, such as high quantum yield, preferable selectivity, for long-term and real-time monitoring of targets of interest.

Our group focuses on the optical property and application of carbon dots. It has been found that CDs presented the excitation wavelength-dependent or independent emission. To improve the quantum yield of carbon dots, carbon dots were doped with nitrogen and germanium which have been applied to biochemical analysis and bioimaging, such as phosphate,tetracycline,mercury (II).For example, a simple method for phosphate (Pi) detection was established by developing an off-on fluorescence probe of europium-adjusted CDs, which has been successfully applied to the detection of Pi in very complicated matrixes such as artificial wetlands system. This work has been highly cited and greatly appreciated.
