Abstract
A novel efficient two-step methodology for the construction of base-functionalized DNA is based on direct aqueous cross-coupling reactions of unprotected nucleoside triphosphates followed by polymerase incorporation. Preliminary applications of the modified DNA in electrochemical detection and bioanalysis are outlined.
