Surface functionalization of carbon micro coils and their selective immobilization on surface-modified silicon substrates.
Surface functionalization of carbon micro coils (CMCs) was performed by acid treatment at different times. Nitric acid oxidation produced CMC with acidic functional groups, although morphology of CMCs was modified after the oxidation. The selective immobilization of as-prepared CMC from an aqueous dispersion was examined on differently surface-modified silicon substrates. It was confirmed that the acid-treated CMC was selectively immobilized on a silicon substrate by chemical bonding with amine-terminated self-assembled monolayers on a silicon substrate, while the pristine CMC was not.
