Sensor array integrated electrochemical chip, method of forming same, and electrode coating

A method of forming an electrochemical chip, comprising:

• forming a first plate by:
• depositing a conducting layer on a first support;
• and etching said conducting layer to form an electrode array;
• covering at least one electrode of said electrode array with a coating doped with a ferrocene compound;
• forming a second plate by:
• etching an opening in a second support;
• bonding said second plate to said first plate such that said first plate and said second plate define a cavity, with said electrode array being within said cavity, wherein said coating is a supported bilayer lipid membrane.
