Abstract

Hybridisation of oligonucleotide micro-and nano-structures, formed using far-and near-field optical lithography, with Raman dye-labelled silver nanoparticles functionalised with complementary oligonucleotides yields striking contrast, attributed to Raman "hot-spot'' formation, and enables rapid, convenient read-out by Raman microscopy.
