| 1 | Nitrogen-doped fluorescence carbon dots as multi-mechanism detection for iodide and curcumin in biological and food samples显示文摘Iodine ion is one of the most indispensable anions in living organisms,particularly being an important substance for the synthesis of thyroid hormones.Curcumin is a yellow-orange polyphenol compound derived from the rhizome of Curcuma longa L.,which has been commonly used as a spice and natural coloring agent,food additives,cosmetics as well as Chinese medicine.However,excess curcumin may cause DNA inactivation,lead to a decrease in intracellular ATP levels,and trigger the tissue necrosis.Therefore,quantitative detection of iodine and curcumin is of great significance in the fields of food and life sciences.Herein,we develop nitrogen-doped fluorescent carbon dots(NCDs)as a multi-mechanism detection for iodide and curcumin in actual complex biological and food samples,which was prepared by a one-step solid-phase synthesis using tartaric acid and urea as precursors without adding any other reagents.An assembled NCDs-Hg^(2+) fluorescence-enhanced sensor for the quantitative detection of I^(-) was established based on a fluorescence“turn-off-on”mechanism in a linear range of 0.3-15μM with a detection limit of 69.4 nM and successfully quantified trace amounts of I^(-) in water samples and urine sample.Meanwhile,the as-synthesized NCDs also can be used as a fluorescent quenched sensor for curcumin detection based on the synergistic internal filtration effect(IFE)and static quenching,achieving a good linear range of 0.1-20μM with a satisfactory detection limit of 29.8 nM.These results indicate that carbon dots are potential sensing materials for iodine and curcumin detection for the good of our health. | Xiaodan Tang Hongmei Yu Brian Bui Lingyun Wang Christina Xing Shaoyan Wang Mingli Chen Zhizhi Hu Wei Chen | 2021 | Bioactive Materials2021，6，6： | 11 |

| 3 | Aggregation-induced emission luminogens for highly effective microwave dynamic therapy显示文摘Aggregation-induced emission luminogens(AIEgens)exhibit efficient cytotoxic reactive oxygen species(ROS)generation capability and unique light-up features in the aggregated state,which have been well explored in image-guided photodynamic therapy(PDT).However,the limited penetration depth of light in tissue severely hinders AIEgens as a candidate for primary or adjunctive therapy for clinical applications.Coincidentally,microwaves(MWs)show a distinct advantage for deeper penetration depth in tissues than light.Herein,for the first time,we report AIEgen-mediated microwave dynamic therapy(MWDT)for cancer treatment.We found that two AIEgens(TPEPy-I and TPEPy-PF6)served as a new type of microwave(MW)sensitizers to produce ROS,including singlet oxygen(1O2),resulting in efficient destructions of cancer cells.The results of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT)and live/dead assays reveal that the two AIEgens when activated by MW irradiation can effectively kill cancer cells with average IC-50 values of 2.73 and 3.22μM,respectively.Overall,the ability of the two AIEgens to be activated by MW not only overcomes the limitations of conventional PDT,but also helps to improve existing MW ablation therapy by reducing the MW dose required to achieve the same therapeutic outcome,thus reducing the occurrence of side-effects of MW radiation. | Nil Kanatha Pandey Wei Xiong Lingyun Wang Wei Chen Brian Bui Jian Yang Eric Amador Mingli Chen Christina Xing Aseem Atul Athavale Yaowu Hao Wirya Feizi Lloyd Lumata | 2022 | Bioactive Materials2022，7，1： | 0 |

| 5 | Real-time SERS monitoring anticancer drug release along with SERS/MR imaging for pH-sensitive chemo-phototherapy显示文摘In situ and real-time monitoring of responsive drug release is critical for the assessment of pharmacodynamics in chemotherapy.In this study,a novel pH-responsive nanosystem is proposed for real-time monitoring of drug release and chemo-phototherapy by surface-enhanced Raman spectroscopy(SERS).The Fe3O4@Au@Ag nanoparticles(NPs)deposited graphene oxide(GO)nanocomposites with a high SERS activity and stability are synthesized and labeled with a Raman reporter 4-mercaptophenylboronic acid(4-MPBA)to form SERS probes(GO-Fe3O4@Au@Ag-MPBA).Furthermore,doxorubicin(DOX)is attached to SERS probes through a pH-responsive linker boronic ester(GO-Fe3O4@Au@Ag-MPBA-DOX),accompanying the 4-MPBA signal change in SERS.After the entry into tumor,the breakage of boronic ester in the acidic environment gives rise to the release of DOX and the recovery of 4-MPBA SERS signal.Thus,the DOX dynamic release can be monitored by the real-time changes of 4-MPBA SERS spectra.Additionally,the strong T2 magnetic resonance(MR)signal and NIR photothermal transduction efficiency of the nanocomposites make it available for MR imaging and photothermal therapy(PTT).Altogether,this GO-Fe3O4@Au@Ag-MPBA-DOX can simultaneously fulfill the synergistic combination of cancer cell targeting,pH-sensitive drug release,SERS-traceable detection and MR imaging,endowing it great potential for SERS/MR imaging-guided efficient chemo-phototherapy on cancer treatment. | Xueqin Huang Bingbing Sheng Hemi Tian Qiuxia Chen Yingqi Yang Brian Bui Jiang Pi Huaihong Cai Shanze Chen Jianglin Zhang Wei Chen Haibo Zhou Pinghua Sun | 2023 | Acta Pharmaceutica Sinica B2023，13，3： | 0 |
