The synthesis of a benzotriazole azo dye phosphoramidite and the subsequent use in solid phase synthesis of oligonucleotides is reported. The azo dye is shown as a surface enhanced resonance Raman label for oligonucleotides that is capable of immobilisation of the oligonucleotide on metal surfaces such as silver nanoparticles.
