DOPA (3,4-dihydroxyphenyl-L-alanine), a catecholic amino acid containing proteins to be responsible for the versatile adhesion of Mussels to various substrates under harsh and wet conditions. The catechol redox chemistry of DOPA in Mussel adhesive plaques precisely control its interfacial adhesive and internal cohesive functionality. Therefore, a better understanding of interfacial DOPA redox chemistry is essential for developing underwater biomedical adhesives and coating materials. The present work deals with the comparative study of surface binding ability and possible oxidative crosslinking property of the synthesised chain substituted DOPA acrylamides with varioussubstrates. The plausible mechanism of surface functionalisation and their order of correlation has been proposed on the evaluation of its atomic force microscopy, contact angle measurements, X-ray photoelectron spectroscopy, UV-Visible spectroscopy and cyclic voltammetric studies.
