注: A:Multi-color fluorescence imaging system was composed of a clinically applicable fiber optic endoscope and light source; B:Cylindrical light diffuser with a NIR laser system; C:The endoscope was put into peritoneal cavity through a small incision,and the abdomen was inflated with air. Subseq...
To overcome these limitations, a near-infrared (NIR)-II laser-mediated photo-Fenton-like reaction based on a plasmonic self-doped semiconductor was proposed as a mild enhancement strategy to enhance the immune responses. Experimental simulations and results of plasmonic Cu 9 S 8 show that the ...

本文要点:作者开发了一种基于新型AIE染料(ZSY-TPE)的多功能NIR-II光学诊疗平台,并将其用于单束激光激活的、成像指导的光热-光动力联合治疗。体内实验研究证实,ZSY-TPE可以对小鼠4T1肿瘤和金黄色葡萄球菌感染模型有高性能的NIR-II引导联合光疗特点,且无明显副作用。因此,作者提出ZSY-TPE作为强大的光热疗平台,可用于...
Angew. Chem. :双金属协同策略合成NIR-II吸收的碳龙配合物 在光热肿瘤治疗中,近红外二区光(NIR-II,1000-1350nm)相较于近红外一区光(800-1350nm)具有更强的组织穿透性和更低的光毒性,应用潜力更大。目前报道的NIR-II吸收材料局限于有机大π共轭分子、超分子自由基、无机材料以及共轭聚合物纳米颗粒。开发新型...
