Strong plasmonic fluorescence enhancement of individual plant light-harvesting complexes

Farooq Kyeyune, Joshua L. Botha, Bertus van Heerden +4

Plasmonic coupling of metallic nanoparticles and adjacent pigments can dramatically increase the brightness of the pigments due to the enhanced local electric field. Here, we demon…
