摘要：
A disposable and sensitive screen-printed electrode was fabricated on a polyimide film substrate using an ink containing conductive boron-doped diamond powder (BDDP). The BDDP-printed electrode exhibited a wider potential window and lower background current in an aqueous electrolyte than a carbon-printed electrode, and the signal-to-background ratio of the redox peak for ferri/ferrocyanide was greater at the BDDP-printed electrode than at the carbon-printed electrode. Electrode fouling during potential cycling in the presence of dopamine was found to be less at the BDDP-printed electrode than at the carbon-printed electrode. Thus the BDDP-printed electrode should be useful as a disposable, sensitive and low-fouling platform for bio- and electrochemical sensors compared to conventional carbon-printed electrodes.
