We designed and explored self-assembled gold nanoparticles (SAGNPs) by introducing dithiol modified polyethylene glycol (PEG) for internanoparticle cross-linking. SAGNPs could enhance uptake into cancer cells and be disintegrated by glutathione (GSH) to achieve tumor microenvironment-activated biodegradation. This assembled structure improved the photothermal effect compared to single gold nanospheres.
我们通过引入二硫醇修饰的聚乙二醇(PEG)进行纳米粒子间交联,设计并探索了自组装金纳米粒子(SAGNPs)。SAGNPs可增强对癌细胞的摄取,并被谷胱甘肽(GSH)分解以实现肿瘤微环境激活的生物降解。与单个金纳米球相比,这种组装结构改善了光热效应。
