Published: Feb. 11, 2025

Sonodynamic therapy (SDT) is a noninvasive approach to tumor treatment, with ongoing efforts being focused on developing highly effective sonosensitizers low toxicity. Herein, liquid-phase stripping technique was introduced as simple reflux method for synthesizing ultrasmall Mn-PCN-224 nanodots (MM NDs). Compared PCN-224 nanodots, the synthesized MM NDs, which function renal-clearable nanoagents, produced 2.42 times more reactive oxygen species (ROS) under identical ultrasound (US) irradiation conditions. In vivo and in vitro experiments revealed that A549 lung cancer cells treated NDs US H2O2 exhibited relative cell viability of ∼9% inhibition rate ∼91%. This result demonstrates can efficiently increase effectiveness SDT by leveraging their catalase-like activity size (4 nm) prevent ROS quenching. Furthermore, these nanoagents could be effectively utilized photoacoustic (PA) imaging track accumulation tumors monitor alleviation hypoxic microenvironment. Notably, ND-mediated demonstrated superior penetration depth compared PDT, making it inhibiting contralateral while facilitating deep-tissue treatment. Thus, this study introduces promising potential PA-guided SDT, thereby paving way treatment strategies.

Despite its antitumor promise, sonodynamic therapy (SDT)'s efficacy in immune activation requires enhancement, primarily due to the hypoxic tumor microenvironment (TME) and insufficient targeting of sonosensitizers specific subcellular regions. Herein, we developed macrophage membrane (MM)-intermingled fusogenic liposomes (MFL) optimize sonoimmunotherapy that encapsulate catalase (CAT) within core incorporate sonosensitizer chlorin e6 (Ce6) outer shell (CAT@MM-MFL-Ce6). The MM confers evasion properties promotes nanoparticles' targeted accumulation tissue. fusion effect enables Ce6 anchor onto cancer cell facilitates direct delivery CAT into cytoplasm, bypassing endosomal degradation. Upon ultrasound stimulation, generated reactive oxygen species directly damage plasma membrane, initiating Caspase 3/Gasdermin E-mediated pyroptosis pathway. Concurrently, encapsulated efficiently decompose H₂O₂ thus enhancing local levels tumors. Contributed by these effects, combination nanosonosensitizer-augmented SDT checkpoint agent successfully reverse immunosuppressive TME, driving a potent response inhibits primary growth, distant metastasis, lung metastases an orthotopic triple-negative breast model.
