The present invention discloses the application of a water-soluble and positively charged fluorescent probe TPA-3Py for the detection of sodium heparin. TPA-3Py is obtained by covalently connecting three methylated vinylpyridines to the three arms of a triphenylamine molecule respectively. Heparin can induce the aggregation-induced emission effect of this fluorescent molecule. With the increase of the heparin content, the fluorescence intensity increases significantly, showing a good fluorescence turn-on response, overcoming the deficiency that the fluorescence probe quenches due to aggregation during the detection of heparin in the prior art. When a 10 μM aqueous solution of TPA-3Py is used for the detection of heparin, a stable fluorescence intensity is achieved within 5 minutes, the linear range is 0 - 6.14 mg / L (R<supgt;2< / supgt> = 0.9938), the lowest detection limit is 49.53 ng / mL, and the quantum yield reaches 4.85%. For the detection of sodium heparin, the TPA-3Py probe adopted in the present invention overcomes the quenching phenomenon caused by aggregation and exhibits a significant AIE effect.
