| 1 | Specific Recognition of Breast Cancer Cells In Vitro Using Near Infrared-Emitting Long-Persistence Luminescent Zn_3Ga_2Ge_2O_(10):Cr^(3+)Nanoprobes显示文摘In this paper, near-infrared emitting long-persistence luminescent Zn3Ga2Ge2O10:Cr3?(ZGG) nanoparticles with diameters of 30–100 nm and bright luminescence were prepared by a sol–gel synthesis method. After the surface amination, the nanoparticles were further bioconjugated with breast cancer-specific monoclonal antibody(anti-Ep CAM) to form ZGG-Ep CAM nanoprobes which can specifically target breast cancer cell lines(MCF7) in vitro. The results of in vitro images show that the luminescence signals from the cells treated with ZGG-Ep CAM nanoprobes are stronger than those from cells treated with ZGG-unconjugated antibody, indicating that the prepared ZGG-Ep CAM nanoprobes possessed excellent specific recognition capability. Furthermore, due to their long afterglow properties, the imaging could persist more than 1 h. Therefore, these nanoprobes could not only provide a high specificity detection method for cancer cells but also realize the long-time monitoring. Developed near-infrared emitting long-persistence luminescent nanoprobes will be expected to find new perspectives for cell therapy research and diagnosis applications. | Jinlei Li Junpeng Shi Jiangshan Shen Huizi Man Mingxi Wang Hongwu Zhang | 2015 | Nano-Micro Letters2015，7，2： | 4 |
| 2 | Ratiometric sensing lysosomal pH in inflammatory macrophages by a BODIPY-rhodamine dyad with restrained FRET显示文摘Inflammation,as the pathophysiological response of body to harmful stimuli,leads to changes in cellular microenvironment.To research pH changes in lysosomes of macrophages during inflammation,we designed a FRET(F(o|')rster resonance energy transfer)based probe,BDP-RhB.The probe showed good lysosome targeting ability,wide response range of pH from 8.0 to 4.0 with significant ratio(I582/I518)change from 0.6 to 3.4,and good reversibility and sustainability.By applying BDP-RhB,we found a decrease of lysosomal pH of macrophages during inflammation. | Yu Yan Xiaodong Zhang Xinfu Zhang Ning Li Huizi Man Lingcheng Chen Yi Xiao | 2020 | Chinese Chemical Letters2020，31，5： | 2 |
| 3 | Forthrightly monitoring ferroptosis induced by endoplasmic reticulum stresses through fluorescence lifetime imaging of microviscosity increases with a specific rotor显示文摘To test the hypothesis that the microviscosity changes of Endoplasmic Reticulum(ER)can be a useful indicator of ferroptosis promoted by ER Stresses(ERS),a new ER targeting viscosity rotor,L-Vis-1 was developed and applied in the quantitation of viscosity by FLIM imaging in live cells.The FLIM imag-ing exhibited an excellent resolution almost as good as the corresponding confocal imaging,more sig-nificantly,during ferroptosis processes promoted by different types of ERS,the viscosity increases were clearly monitored by FLIM of L-Vis-1 within ER,which has not been demonstrated before. | Chuanhao Liu Lin Zhou Lijuan Xie Ying Zheng Huizi Man Yi Xiao | 2022 | Chinese Chemical Letters2022，33，5： | 0 |
