DOI: 10.1002/advs.202205759
Abstract: Non‐alcoholic fatty liver disease is the most common liver disorder worldwide, which strongly correlates to obesity, diabetes, and metabolic syndromes. Complementary to mainstream liver diagnostic modalities, photoacoustic tomography (PAT) can provide high‐speed images with functional… read more here.

DOI: 10.1021/acsnano.9b01411
Abstract: Tumor phototheranostics in the second near-infrared window (NIR-II, 1000-1700 nm) holds great promise due to high spatiotemporal precision, enhanced penetration depth, and therapeutic efficacy. However, current "always-on" NIR-II phototheranostic agents remain restricted by the inherent… read more here.
