- Abstract
Superior QY maintains sufficient signal strength to enable NIR-II imaging with deep penetration and high resolution I in vivo i , which avoids nonradiative decay processes ([113]), and reduces quenching effects due to aggregation ([17]) and strong interactions with water molecules outside the NIR-II probes ([111]). NIR-II photoacoustic imaging of brain diseases Because of much less attenuation of ultrasonic waves and higher photothermal conversion efficiency (PCE) in biological tissues, NIR-II photoacoustic imaging has attracted attention in biomedical fields ([90]). NIR-II probes According to the emission wavelength, NIR probes can be divided into NIR-I and NIR-II probes.

Graph: Figure 1: Depth of penetration of brain tissue with different wavelengths of light and principle of NIR-II imaging ([51]; [81]; [108]).(A) From UV to NIR-II, the tissue penetration depth is gradually increased with the increasing of wavelength, and the depth of NIR-II photoacoustic is up to 7.04 mm.
