Described herein are methods, compositions and articles of manufacture involving neutral conjugated polymers including methods for synthesis of neutral conjugated water-soluble polymers with linkers along the polymer main chain structure and terminal end capping units. Such polymers may serve in the fabrication of novel optoelectronic devices and in the development of highly efficient biosensors. The invention further relates to the application of these polymers in assay methods.
tactic can intensify ferroptosis of tumor cells and vice versa. Diminishing exosomal suppression and establishing a nexus of antiexosomal PD-L1 and ferroptosis may rescue the discouraging antitumor immunity. Here, we engineered phototheranostic metal-phenolic networks (PFG MPNs) by an assembly of semiconductor polymers encapsulating ferroptosisinducer (Fe3+) and exosome inhibitor (GW4869). The PFG MPNs
肿瘤来源的外泌体可以抑制树突状细胞 (DC) 和 T 细胞的功能。外泌体程序性死亡配体 1 (PD-L1) 的过度分泌导致对 PD-1/PD-L1 免疫疗法的治疗抵抗和临床失败。通过抗外泌体 PD-L1 策略恢复的 T 细胞可以加剧肿瘤细胞的铁死亡,反之亦然。减少外泌体抑制并建立抗外泌体 PD-L1 和铁死亡的联系可能会挽救令人沮丧的抗肿瘤免疫。在这里,我们通过封装铁死亡诱导剂(Fe 3+)的半导体聚合物组装设计了光疗金属酚网络(PFG MPN))和外泌体抑制剂(GW4869)。PFG MPN 为精确的光热疗法 (PTT) 提供了卓越的近红外 II 荧光/光声成像跟踪性能。PTT 增强的免疫原性细胞死亡缓解了 DC 成熟时的外泌体沉默。GW4869 介导基于 PD-L1 的外泌体抑制活化 T 细胞并增强铁死亡。这种 PTT 与抗外泌体 PD-L1 的新型协同作用增强了铁死亡,在 B16F10

The present invention includes optical coatings containing ultraviolet curable monomers employing a bromine substituted fluorene structure. The fluorene backbone of the monomers of the present invention may also be functionalized with one or more polymerizable or reactive functionalities, and most readily at the 9 position. Compositions of the present invention include the reactive bromosubstituted fluorenes combined with inorganic nanoparticles, particularly nanoparticles with reactive surface modifiers exhibiting polymerizable functionality. Reactive high index nanoparticles such as surface modified zirconia are contemplated.
