Effect of DNA on the oxidase mimetic activity of CeO2 nanowires

doi:10.7523/j.issn.2095-6134.2019.02.016

Abstract

Abstract: 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.

Key words: CeO₂ nanowires, DNA, UV-Vis spectrophotometry, oxidase, inhibition
