利用改进的Hummers法氧化鳞片石墨，获得富含羟基和羧基的氧化石墨烯量子点(GOQDs)。通过透射电子显微镜、X射线衍射、红外光谱及拉曼光谱测试表征其理化性质。此外，利用鸡卵清蛋白(OVA)作为模式抗原，构筑GOQDs/OVA纳米疫苗并评估其载量、安全性、免疫效力等。结果显示，GOQDs/OVA纳米疫苗直径在5 nm左右，具有高度的水分散性和稳定性。其对OVA的最大负载量约为500 mg·g^-1，在pH=5.5和7.4环境下24 h的释放率分别为74.65%和56.93%，表现出pH刺激响应释放性能。当GOQDs浓度在500 μg·mL^-1以下时，不会引起溶血、细胞损伤、重要组织发生病变等现象。免疫后，与OVA单独免疫对照组相比，GOQDs/OVA纳米疫苗可以诱导产生高水平的免疫球蛋白G(IgG)、免疫球蛋白G1(IgG1)及免疫球蛋白G2a(IgG2a)抗体，提高白细胞介素(IL)-1β、IL-2、IL-4和IL-6、肿瘤坏死因子-α(TNF-α)和γ干扰素(IFN-γ)的分泌，同时促进脾中辅助性(CD4⁺)和细胞毒性(CD8⁺)T淋巴细胞百分比的增加。

A novel one-dimensional (1D) polycarbonyl coordination polymer [Cu(BGPD)(DMA)(H₂O)]·DMA (named Cu-BD, H₂BGPD=N, N′-bis(glycinyl)pyromellitic diimide; DMA=dimethylacetamide) was synthesized, and evaluated as a cathode material for lithium - ion batteries (LIBs) for the first time. The electrochemical performance study revealed that the Cu-BD cathode exhibited better cycling stability and a specific capacity of 50 mAh·g^-1 after 100 cycles at a current density of 50 mA·g^-1. The study of the reaction mechanism for the Cu-BD electrode discloses that both BGPD^2- ligands and Cu(Ⅱ) ions may take part in the electron-transfer process during charging and discharging.
