NIR fluorescence has shown great potential in bioscience, but low quantum-yield has largely impeded research on most NIR fluorophores. Here, scientists in China use asymmetric plasmonic nano-antennas to drastically enhance an NIR dye's single-molecule fluorescence intensity. The asymmetry provides an additional tuning parameter that offers new possibilities to modulate near-field and far-field properties of the plasmonic modes, thereby improving fluorescence without compromising the molecule's p...
