Cathodic pretreatment improves the resistance of boron-doped diamond electrodes to dopamine fouling

• Pretreatments of boron-doped diamond are known to alter its response.
• Cathodic pretreatment grants an improved resistance to dopamine fouling.
• This result can be related to the properties of bio-adhesives.

The resistance of cathodically and anodically treated boron-doped diamond electrodes to dopamine fouling was investigated. It was found, using cyclic voltammetry and electrochemical impedance spectroscopy, that the cathodic preparation offers an increased resistance to fouling, in addition to an enhanced electrochemical response.
