Diamond surface functionalization with biomimicry – Amine surface tether and thiol moiety for electrochemical sensors.

Highlights: [•] Diamond surfaces were functionalized with organic molecules using a novel approach. [•] Used biomimicry to select a molecule to bind NO, similar to the human body. [•] Molecular orbital theory predicted the molecule-analyte oxidation behavior. [•] A thiol moiety was attached to an amine surface tether on the diamond surface. [•] XPS analysis verified each surface functionalization step. [ABSTRACT FROM AUTHOR]
