NIR Absorbing Dyes For Photo Acoustic Imaging

Near infrared absorbing dyes improve penetration depth in photoacoustic imaging through decreased light scattering. 

Akita NIR dye characteristics:
-High absorbance at 750-870 nm, minimal emission 
-Strong photoacoustic response
-Photostable 
-Conjugatable to biomolecules for targeted tissue imaging
