| 1 | Self-assembled all-inclusive organic-inorganic nanoparticles enable cascade reaction for the detection of glucose显示文摘Traditional colorimetric glucose biosensor generally involves complex assay procedures.Free labile enzymes and peroxidase substrates are used separately for triggering a chromogenic reaction.These limits result in inferior enzyme stability and defective enzymatic catalytic efficiency,making it hard to routinely utilize them for the direct and fast test of glucose.In this work,we provide an all-inclusive substrates/enzymes nanoparticle employed 3,3’5,5’-tetramethylbenzidine(TMB) as chromogenic substrates and glucose oxidase(GOx)/horseradish peroxidase(HRP) as signal amplifier enzymes(TMB-GH NPs) by the molecule self-assembly technique.The 'all-inclusive' nanoparticles can realize the tandem colorimetric reactions,and the oxidation product of TMB(ox-TMB) exhibits a strong NIR laserdrive n photothermal effect,thus allowing qua ntitative photothermal detection of glucose.Owing to the restriction of the molecular motion of GOx,HRP,and TMB,the distance of mass transfer between substrates was s hortened largely,leading to improved catalytic activity for glucose.Overall,our strategy will simplify the analysis procedure,furthermore,these integrated nanoparticles not only display higher stability and activity than that of the free GOx/HRP system and possesses an excellent performance for colorimetric and photothermal bioassay of glucose simultaneously.We believe that this unique technique will give good inspirations to develop simple and precise methods for bioassay. | Ximei Sun Yan Li Qian Yang Yunwei Xiao Yuting Zeng Jindi Gong Ziyu Wang Xiaofeng Tan He Li | 2021 | Chinese Chemical Letters2021，32，5： | 1 |
| 2 | Intermetallic PdBi aerogels with improved catalytic performance for the degradation of organic pollutants in water显示文摘It is always highly pursued to develop efficient and durable catalysts for catalytic applications.Herein,intermetallic PdBi aerogels with tunable activity were prepared successfully via a surfactant-free spontaneous gelation process.The prepared PdBi aerogels have a three-dimensional high porous structure and plentiful active sites pervaded on the ultrathin interlinked nanowires network.These unique structures,as well as the synergistic effect between Pd and Bi,can accelerate mass and electron transfer,and improve the atom utilization ratio of Pd atoms to promote the catalytic efficiency.As a proofof-concept application,the optimized Pd_(2) Bi_(1) aerogels exhibit 4.2 and 6.2 times higher catalytic activity for the reduction of 4-nitrophenol(4-NP)and methylene blue(MB)than those of commercial Pd/C,respectively.With the introduction of non-noble metal of Bi,the cost of the resulted Pd Bi aerogels can be dropped signi ficantly while the catalytic capability of Pd Bi aerogel will be improved sharply.This strategy will bring good hints to rationally design fine catalysts for various applications. | Xiaofeng Tan Jun Qin Yan Li Yuting Zeng Jindi Gong Gengxiu Zheng Feng Feng He Li | 2021 | Chinese Chemical Letters2021，32，4： | 0 |
