However, the trigger of ICD on the basis of chemotherapy and phototherapy meets the obstacles of serious side effect and poor penetration ability, which seriously impedes the therapeutic effect. The development of sonodynamic immunotherapy with the evoking of ICD presents high promise for cancer treatment with high efficacy. Herein, high performance aggregation-induced emission (AIE) sonosensitizer is constructed on the basis of the engineering structure modulation for sonodynamic-augmented immunotherapy. By regulating the intermolecular interaction and pull-push electronic effect, sonosensitizer bearing AIE feature and amplified sono-sensitizing effect is developed. In addition, in vitro observation demonstrated that thiolate-substituted segment incorporation endows the molecules with enhanced cellular uptake efficiency and improved tumor cell eradication ability. More importantly, the developed sonosensitizer could efficiently evoke ICD upon the trigger of ultrasound, which allows for the efficient tumor eradication both at cellular level and in solid tumor. The inhibition of primary tumor and further boost systemic immunity response with the complete elimination toward the distant tumor is achieved. The investigation highlights the promise of utilizing AIE sonosensitizers in sonodynamic immunotherapy to conquer the current limitation of immunotherapy in solid tumor treatment.</p>","PeriodicalId":72127,"journal":{"name":"Aggregate (Hoboken, N.J.)","volume":"6 6","pages":""},"PeriodicalIF":13.9,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agt2.70058","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the different NPs, lipid nanoparticles (LNPs) have revolutionized the field of nanomedicine by providing various advantageous features for drug delivery. The versatile characteristics of LNPs synergize well with cell membranes’ biomimetic properties, creating hybrid structures with enhanced functionalities for diverse biomedical applications.

High-performance fluorescent probes are the cornerstone of high-quality NIR-III 3P FLI. However, the construction of such probes is often hindered by inherent trade-offs in molecular design principles, posing significant challenges for their performance optimization and practical application. Here, we propose a straightforward and effective strategy based on π-bridge manipulation to reconcile those competing molecular design parameters and substantially enhance 3P fluorescence properties. Leveraging this approach, a robust AIE-active small molecule, named TSSID, was developed, which exhibits bright NIR-I (700–950 nm) emission under 1665 nm NIR-III 3P excitation when formulated into nanoparticles (NPs). Remarkably, upon retro-orbital injection into mice following craniotomy, TSSID NPs achieved the best performance in deep-brain angiography among all reported organic 3P materials in terms of vascular imaging depth, signal-to-background ratio, spatial resolution, and hemodynamic imaging depth. Additionally, TSSID NPs demonstrated outstanding biocompatibility through systematic biosafety evaluations.

As the area increases, this results in nonuniform preparation of the HTLs, which significantly reduces the efficiency and reliability of the device at the module level. To tackle this significant challenge, we propose a strategy for a dual-fiber network structure based on polymer HTLs. This strategy involves the use of organic solar cell polymer donor material (PM6) and poly(3-hexylthiophene) (P3HT), which are spontaneously interwoven into micron-sized fiber crystals to establish efficient carrier transport channels. This unique structure not only accelerates charge extraction but also takes advantage of the inherent benefits of polymers, such as excellent printability and homogeneous film formation while enhancing the protection of the perovskite layers. The resulting devices demonstrate a <i>V</i><sub>OC</sub> of 1.18 V and a champion PCE of 24.90%, which is higher than the pristine devices (the PCE is 22.87%). Moreover, due to the improved printing characteristics, the PSMs prepared by blade-coating also demonstrate a high PCE of 15.15% within an aperture area of 100 cm<sup>2</sup>.
