Schematic illustration of the structure of OI-NP–mediated PSDT for MH7A cells. Liquid-gas transition and photodynamic reaction occurred in the OI-NPs under laser irradiation. The phase-transited OI-NPs were ruptured when exposed to low-intensity focused ultrasound and it caused a sonodynamic reaction.

Abbreviations: OI-NPs, oxygen and indocyanine green loaded nanoparticles; PDT, photodynamic therapy; RA-FLSs, rheumatoid arthritis fibroblast-like synoviocytes; SDT, sonodynamic therapy; US, ultrasound.
