Abstract:
Terbium doped graphitic carbon nitride (g-C3N4:Tb) gives rise to two exceptional emissions at λex/λem = 290/490 nm and 290/546 nm, with extremely narrow peak widths of FWHM < 12 nm as well as a large Stokes shift of >200 nm. The modification of g-C3N4:Tb with HOOC-PEG-COOH provides a ratiometric fluorescent probe which ensures highly sensitive detection of alkaline phosphatase (ALP) activity based on the inner filter effect (IFE).

Labeling DNA Probes
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...
