Plasmon-enhanced fluorescence from single fluorophores end-linked to gold nanorods.
We reported a method to fabricate fluorescent probes preferentially end-linked to Au nanorods. In comparison with organic dyes, the single nanocomplexes provide significant improvement in signal brightness. The bioconjugated nanoantenna structure implicates an approach that is more convenient and amenable to integration for photonic, optoelectronic, and biotechnological applications.
