Abstract: The Staudinger ligation is a type of metal-free catalyzed click reaction between organic azide and phosphine under the mild conditions like at room temperature and in the water solution. Due to its bio-orthogonality and no potential cytotoxicity,Staudinger ligation is now widely used in the surface functionalization of materials,synthesis and labelling of various biological macromolecules. At the same time,there is great development space for applying Staudinger ligation in the synthesis and delivery of drugs and biosensors. In this review,the Staudinger ligation is described in detail involving the reaction mechanism,the factors influencing the reaction kinetics,the yield of the ligation and the reaction process,and the biomarker technology mediated by the ligation. On these bases,the biosensing applications mediated by the Staudinger ligation are discussed,including fluorescent biosensors targeting nucleic acids and small molecules,the applications of cell imaging technology in nucleic acid and glycan,and the applications in drug synthesis and delivery. At last,the future development trend of the Staudinger ligation is forecasted and the application prospects in the biosensing are presented.
