    Morphology-dependent resonance enhanced nonlinear photoacoustic effect in nanoparticle suspension: a temporal-spatial model by Zheng, Zesheng, Bindra, Anivind Kaur, Jin, Haoran, Sun, Quqin, Liu, Siyu, Zheng, Yuanjin

    Published 2022
    “…By extending this phenomenon to pulse-laser irradiated nanoparticle suspension, we demonstrate that such collective optical/thermal enhancement can give rise to the nonlinear photoacoustic (PA) generation. In this study, a temporal-spatial analytical expression is derived to quantitatively describe the nonlinear PA signal generation from nanoparticles, incorporating the Grüneisen increase at the microscopic individual particle level and MRDs enhancement at the macroscopic suspension level. …”

    Mo₂C‐derived polyoxometalate for NIR-II photoacoustic imaging‐guided chemodynamic/photothermal synergistic therapy by Liu, Gongyuan, Zhu, Jiawei, Guo, Heng, Sun, Aihui, Chen, Peng, Xi, Lei, Huang, Wei, Song, Xuejiao, Dong, Xiaochen

    Published 2023
    “…In addition to the strong ability to produce singlet oxygen (1O2) presumably via Russell mechanism, its excellent photothermal conversion enhances the CDT effect, offers additional tumor ablation modality, and permits NIR-II photoacoustic imaging. Benefitting from the reversible redox property of molybdenum, the theranostics based on POM can escape from the antioxidant defense system. …”
