摘要
Background: Cross-linked porous carbon nanofibers (CNF) was successfully prepared by electrospinning and high-temperature carbonization. Polyacrylonitrile (PAN) as the carbon source and Genipin as the cross-linking agent were used to prepare Cross-linked porous carbon nanofibers (CNF). Method and Material: The field emission Scanning Electron Microscopy (SEM), Transmission Electron Microscope (TEM), Automatic Specific Surface and Porosity Analyzer Brunner Emmet Teller (BET), X-ray Diffraction (XRD), A laser confocal microspectroscope (Raman, XploRA PLUS, Horiba) were used to characterize materials. The CNF suspension was dropped on the surface of the bare glassy carbon electrode by the drip coating method to obtain a CNF modified electrode. Cyclic voltammetry was used to study the electrochemiluminescence behavior of difenidol hydrochloride on CNF modified glassy carbon electrode (Glassy Carbon Electrode, GCE). Results and Discussion: Herein, we synthesised a kind of Crosslinked Carbon Nanofibers and designed a novel ECL biosensor, Under the optimal conditions, the concentration of difenidol hydrochloride has a linear relationship with the peak current in the range of 8.0×10-8 to 1.0×10-4mol/L, the correlation coefficient is R2=0.997, with a low detection limit (1.2×10- 8 mol/L). Difenidol hydrochloride in difenidol hydrochloride tablets was tested, and the recovery rate of sample addition was 83.17%-92.17%, and the RSD was <5.0%. The designed platform exhibited excellent analytical performance towards difenidol hydrochloride determination.
