Movie S1.

In vivo brightness comparison of ICG and IR-E1050. ICG and IR-E1050 were injected via the tail vein at the recommended doses (67 nmol for IR-E1050 and 64 nmol for ICG), excited with 808-nm excitation, and imaged noninvasively through the skin on an InGaAs SWIR camera using a 1,000-nm long-pass filter at 15 frames per second.
