Abstract

We have been studying fluorescence enhancement from labeled oligonucleotides immobilized inside metallic nanoapertures. Fluorescence enhancement is a direct result of the localized field intensity enhancement within these nanoapertures from plasmonic excitation. We have also been developing specific surface chemistries for metallic films to localize capture oligos only inside these nanoapertures. Some of our recent results are overviewed.
