Abstract

A method for the addition of a benzotriazole moiety to the 5'-terminus of an oligonucleotide via phosphoramidite chemistry has been developed. Use of a monomethoxytrityl protecting group on the benzotriazole allowed fast on-column detritylation purification by reverse-phase HPLC. Surface enhanced Raman scattering (SERS) of the modified oligonucleotides was obtained from silver colloid.
