Resumen:
Fluorescence readout is uniquely powerful forbiological assays and imaging because it combines the detection ofspecific biotargets with high spatial and temporal resolution.Recently, several strategies for the modulation in time offluorescence emission have been proven useful to separate the targetsignal from constant background contributions. Here, we investigatethe emission modulation of organic fluorophores located in thenanometric vicinity of plasmonically heated gold nanorods and applyit to a novel, all-optical homogeneous biosensing scheme. Thecombination of plasmonic heating and temperature sensitivemolecular fluorescence enables the robust quantification of surfacereactions.
