| 1 | Quantum dots-hydrogel composites for biomedical applications显示文摘Quantum dots-hydrogel composites are promising new materials that have attracted extensive attention due to their incomparable biocompatibility and acceptable biodegradability, leading to enormous potential applications for various fields. This review summarizes the recent advances in quantum dots-hydrogel composites with a focus on synthesis methods, including hydrogel gelation in quantum dots(QDs) solution, embedding prepared QDs into hydrogels after gelation, forming QDs in situ within the preformed gel and cross-linking via QDs to form hydrogels. In particularly, biomedical applications as bioimaging,biosensing and drug delivery are also reviewed, followed by a discussion on the inherent challenges of design optimization, biocompatibility and bimodal applications and the prospect of the future development. These results will guide the development of quantum dots-hydrogel composites and provide critical insights to inspire researchers in future. | Wenjie Zhou Zhe Hu Jinxin Wei Hanqing Dai Yuanyuan Chen Siyu Liu Zhongtao Duan Fengxian Xie Wanlu Zhang Ruiqian Guo | 2022 | Chinese Chemical Letters2022，33，3： | 1 |
| 2 | Aqueous synthesis of 79%efficient AgInGaS/ZnS quantum dots for extremely high color rendering white light-emitting diodes显示文摘Over the past few decades,I-III-VI quantum dots(QDs)have attracted considerable attention due to their large Stokes shifts,good eco-friendliness,and wide tunable emissions.In this work,a facile microwave-assisted aqueous route using glutathione(GSH)and citric acid(CA)as dual stabilizers is introduced to synthesize AgInGaS/ZnS(AIGS/ZnS)core/shell QDs.An exceptional photoluminescence quantum yield(PL QY)as high as 79%is successfully achieved,boosting the best performance of water-dispersible AIGS QDs.By varying the Ag/Ga ratio,the PL peak wavelength can be tuned from 547 to 616 nm,and luminescent hydrogel films with different colors are obtained by embedding AIGS/ZnS QDs in polyacrylamide/poly-vinyl alcohol(PAAm/PVA)hydrogels.The white light-emitting diode(WLED)with a high color rendering index(CRI)of 92.1(R_(9)=92.0)and a correlated color temperature(CCT)of 3022 K is fabricated using QDs-PAAm/PVA hydrogel films in combination with a blue InGaN LED chip,indicating that the as-prepared QDs are competitive color-conversion materials for WLEDs. | Zhe Hu Hanxu Lu Wenjie Zhou Jinxin Wei Hanqing Dai b Hong Liu Zhiyong Xiong Fengxian Xie Wanlu Zhang Ruiqian Guo | 2023 | Journal of Materials Science & Technology2023，，3： | 1 |
| 3 | G protein-coupled receptor 35 attenuates nonalcoholic steatohepatitis by reprogramming cholesterol homeostasis in hepatocytes显示文摘Nonalcoholic fatty liver disease(NAFLD)is the most common chronic liver disease worldwide.Fat accumulation“sensitizes”the liver to insult and leads to nonalcoholic steatohepatitis(NASH).G protein-coupled receptor 35(GPR35)is involved in metabolic stresses,but its role in NAFLD is unknown.We report that hepatocyte GPR35 mitigates NASH by regulating hepatic cholesterol homeostasis.Specifically,we found that GPR35 overexpression in hepatocytes protected against high-fat/cholesterol/fructose(HFCF)diet-induced steatohepatitis,whereas loss of GPR35 had the opposite effect.Administration of the GPR35 agonist kynurenic acid(Kyna)suppressed HFCF diet-induced steatohepatitis in mice.Kyna/GPR35 induced expression of StAR-related lipid transfer protein 4(STARD4)through the ERK1/2 signaling pathway,ultimately resulting in hepatic cholesterol esterification and bile acid synthesis(BAS).The overexpression of STARD4 increased the expression of the BAS rate-limiting enzymes cytochrome P450 family 7 subfamily A member 1(CYP7A1)and CYP8B1,promoting the conversion of cholesterol to bile acid.The protective effect induced by GPR35 overexpression in hepatocytes disappeared in hepatocyte STARD4-knockdown mice.STARD4 overexpression in hepatocytes reversed the aggravation of HFCF diet-induced steatohepatitis caused by the loss of GPR35 expression in hepatocytes in mice.Our findings indicate that the GPR35–STARD4 axis is a promising therapeutic target for NAFLD. | Xiaoli Wei Fan Yin Miaomiao Wu Qianqian Xie Xueqin Zhao Cheng Zhu Ruiqian Xie Chongqing Chen Menghua Liu Xueying Wang Ruixue Ren Guijie Kang Chenwen Zhu Jingjing Cong Hua Wang Xuefu Wang | 2023 | Acta Pharmaceutica Sinica B2023，13，3： | 0 |
