Plasmonic Photothermal Fluorescence Modulation for Homogeneous Biosensing
Fluorescence readout is uniquely powerful for biological assays and imaging because it combines the detection of specific biotargets with high spatial and temporal resolution. Recently, several strategies for the modulation in time of fluorescence emission have been proven useful to separate the tar...
