Single-molecule fluorescence detection (SMFD) is able to probe, one molecule at a time, dynamical processes that are crucial for understanding functional mechanisms in biosystems. Fluorescence in the Near-infrared (NIR) offers improved Signal to Noise Ratio (SNR) by reducing the scattering, absorption and autofluorescence from biological cellular or tissue samples, therefore, provides high imaging resolution with increased tissue penetration depth that are important for biomedical applications. However, most NIR-emitters suffer from low quantum yield, the weak NIR fluorescence sig ....
