查询词典 alternating

The method by drying/adsorption was used to prepare DNA adsorptively modified electrodes, and thus-resulting DNA-modified electrodes were electrochemically and spectroscopically characterized, including cyclic voltammetry, scanning tunneling microscopy, Raman spectroscopy, in-situ UV/Vis reflection spectroscopy, X-ray photoelectron spectroscopy, and alternating current impedance. Some information about the state of DNA immobilized on electrode surfaces was obtained.
