Paper Abstract

A new fiber optic sensor has been developed for determination of NO using a fluorescent vicinal diaminobenzoacridine (VDABA) probe. The sensitive membrane was prepared from cellulose acetate (CA) embedded with VDABA, which caused a fluorescence recovery based on a photoelectron transfer (PET) mechanism. Modulation of optical phase shift of the sensor is observed with different NO concentrations. Under optimum conditions, a linear calibration (r2=0.9902) was obtained in the range of 1.0×10-8 to 1.0×10-5 mol/L NO concentration with a detection limit of 1.0×10-9 mol/L (S/N=3). This sensor was successfully applied to the determination of NO in the rabbit serum.
