Figure 5

A) 0.79 μL ICG standards in DMSO.

B) ICG Equivalence(725−775 nm, 5 mW/cm2, >795 nm, 1 mm) (μM; mean ± S.D.) of individual 1 mm (0.79 μL) ICG-loaded anion exchange beads expressed as a function of loading concentration.

C) ICG Equivalence(725−775 nm, 5 mW/cm2, >795 nm, 1 mm) (μM; mean ± S.D.) of individual 100 μm HA crystals loaded with Pam78 and calibrated against 100 μm path length ICG standards in DMSO.

D) 100 μm Pam78-labeled HA crystals loaded with a 1 μM ICG Equivalence(725−775 nm, 5 mW/cm2, >795 nm, 1 mm) as viewed on a NIR fluorescence microscope.
