The CeO2 nanowires were synthesized by the hydrothermal method. The sample was characterized by transmission electron microscopy, X-ray diffractometer, and Raman spectrometer. Fourier transform infrared spectrometer and UV-Vis spectrophotometer were used to analyze the interaction between DNA and CeO2 nanowires. The effect of DNA on the oxidase mimetic activity of CeO2 nanowires was further studied by UV-Vis spectrophotometry. The impact of pH on the system and specificity experiment were also studied. The results show that DNA inhibits the oxidase activity of CeO2 nanowires, and the inhibition is specific. This work further promotes the practical application of CeO2 nanowires.
