摘 要: | A superhydrophobic 3D silver nanotree surface enhanced Raman spectroscopy (SERS) substrate was synthesized, and characterized by scanning electron microscopy (SEM), energy dispersive spectrometer (EDS) and X-ray powder diffraction (XRD). Its hydrophobic properties were analyzed by contact angle (CA). Rhodamine B (RB) was used as Raman probe to optimize the conditions. The SERS properties of azithromycin (AZM) on this substrate were investigated, showing that the SERS substrate had a high Raman enhancement effect on AZM. The ISERS presented a good linear relationship with the logarithm concentration of AZM as ISERS= 4098logc+47769(R2=0.987) in the range of 1.0×10-11-1.0×10-9mol/L, and the detection limit was 4 pmol/L. This method was used to analyze AZM content in AZM dispersible tablets, human serum and porcine serum, with the spiked recoveries in the range of 91.2%-118.1% and relative standard deviations of 1.1%-6.2%. © 2023 the authors.
