5-Nitrosalicylic acid can react with human serum albumin(HSA) to form a complex.Based on this,a new method for the determination of proteins by synchronous fluorescence spectra under simulated physiological conditions was established with 5-nitrosalicylic acid as a fluorescence probe.The spectral chara-cterization and the intensity of synchronous fluorescence were related to the value of Δλ,reaction medium and reaction temperature is.Experimental results show that under the optimum conditions,the synchronous fluorescence intensity of the system is in proportion to the concentration of HSA in a range of 3.2×10-8~6.4×10-6 mg/L.The detection limit is 1.17×10-8 mol/L(n=11).The determination of proteins in human serum,urine and saliva samples is performed with satisfactory results,the recovery is within a range of 99.96%~100.04%.
