What is a CO surface chemistry?

The CO chemistry is suitable for immobilizing molecules with an amine function (NH2 group). The immobilization principle is based on the high affinity of sulfur atoms (present in Cystamine) on gold and the reactions between free amine molecules from proteins (or peptides) and aldehyde molecules (present in Glutaraldehyde). In this process, imine links or Schiff’s bases are formed. The link between Cystamine and Glutaraldehyde is also an imine.
