    Abstract

    Single DNA-nanoparticle binding is used to couple the plasmonic fields of nanophotonic bowtie dimers. The binding event is engineered to tune the resonance peak of the bowtie to correspond with a 633 nm laser. Surface enhanced Raman spectroscopy is performed on an individual bowtie, showing that a single DNA-nanoparticle binding event can be recorded.
