  • Near-infrared (NIR) fluorescence imaging >1,000 nm allows deep tissue imaging, but available organic dyes display poor brightness and temporal resolution. Here, the authors synthesize a NIR dye that, upon binding serum proteins, exhibits a 110-fold increase in intensity, giving an 11% quantum yield.

  • In vivofluorescence imaging in the second near-infrared window allows high resolution and tissue penetration. Here, using conjugated polymers, the authors achieve imaging with high spatial and time resolutions capable of resolving mouse femoral artery blood-flow variations within a single cardiac cycle.

  • A renally cleared, water-soluble dye emitting in the near-infrared-imaging (NIR)-II window outperforms a clinically approved NIR-I dye in the in vivo imaging of tumours and their nearby blood and lymphatic vasculatures.

  • Fluorescence imaging in the near-infrared window between 1500–1700 nm (NIR-IIb window) offers superior spatial resolution and tissue penetration depth, but few NIR-IIb probes exist. Here, the authors synthesize rare earth down-converting nanocrystals as promising fluorescent probes for in vivo imaging in this spectral region.
