| 1 | Gate-tunable large-scale flexible monolayer MoS_(2)devices for photodetectors and optoelectronic synapses显示文摘Photodetectors and optoelectronic synapses are vital for construction of artificial visual perception system.However,the hardware implementations of optoelectronic-neuromorphic devices based on conventional architecture usually suffer from poor scalability,light response range,and limited functionalities.Here,large-scale flexible monolayer MoS_(2)devices integrating photodetectors and optoelectronic synapses over the entire visible spectrum in one device have been realized,which can be used in photodetection,optical communication,artificial visual perception system,and optical artificial neural network.By modulating gate voltages,we enable MoS_(2)-based devices to be photodetectors and also optoelectronic synapses.Importantly,the MoS_(2)-based optoelectronic synapses could implement many synaptic functions and neuromorphic characteristics,such as short-term memory(STM),long-term memory(LTM),paired-pulse facilitation(PPF),long-term potentiation(LTP)/long-term depression(LTD),and“learning-experience”behavior.Furthermore,an associative learning behavior(the classical conditioning Pavlov’s dog experiment)was emulated using paired stimulation of optical and voltage pulses.These results facilitate the development of MoS_(2)-based multifunctional optoelectronic devices with a simple device structure,showing great potential for photodetection,optoelectronic neuromorphic computing,human visual systems mimicking,as well as wearable and implantable electronics. | Na Li Congli He Qinqin Wang Jianshi Tang Qingtian Zhang Cheng Shen Jian Tang Heyi Huang Shuopei Wang Jiawei Li Biying Huang Zheng Wei Yutuo Guo Jiahao Yuan Wei Yang Rong Yang Dongxia Shi Guangyu Zhang | 2022 | Nano Research2022，15，6： | 1 |
| 2 | A novel α-fetoprotein-MIP immunosensor based on AuNPs/PTh modified glass carbon electrode显示文摘A new α-fetoprotein-MIP(AFP-MIP) immunosensor based on glass carbon electrode(GCE) modified with polythionine(PTh) and gold nanoparticles(AuNPs) was successfully fabricated for sensitive detection ofα-fetoprotein(AFP). Through controlling electropolymerization, A 'polydopamine(PDA)-AFP' complex was achieved applying AFP as template and dopamine(DA) as imprinted monomers. After elution, the specific cavities can adsorb the target molecules. Using differential pulse voltammetry(DPV) detection,the peak current decreased with the increase in concentration of AFP, and the linear response range of the AFP-MIP immunosensor was from 0.001 ng/mL to 800 ng/mL with the detection limit as low as0.8138 pg/mL. The MIP immunosensor could become a new promising method for the detection of AFP.Furthermore, this MIP sensor was demonstrated in testing AFP in human serum samples with satisfactory results. | Yuxuan Lai Chuanxiang Zhang Yan Deng Gaojian Yang Song Li Congli Tang Nongyue He | 2019 | Chinese Chemical Letters2019，30，1： | 1 |
| 3 | Rapid identification of diarrheagenic Escherichia coli based on barcoded magnetic bead hybridization显示文摘Diarrhea,as a global public health problem,causes a large number of infections and deaths every year.Although Escherichia coli(E.coli)is one of the normal flo ra microorganisms in the human intestinal tract,it has five pathogenic bacteria types that can cause human diarrhea,known as diarrheagenic E.coli.When people are infected,rapid and accurate diagnosis,along with timely treatment,are especially important.Here,we introduce a new method to identify and analyze a large number of pathogenic strains in E.coli by multiplex PCR and barcoded magnetic bead hybridization.Results show that the detection sensitivities of enterohemorrhagic E.coli,enterotoxigenic E.coli,enteropathogenic E.coli,enteroinvasive E.coli and enteroaggregative E.coli were 1.3×10^3 CFU/mL,2×10^4 CFU/mL,4×10^4 CFU/mL,7.2×10^4 CFU/mL and 1.7 CFU/mL respectively.This method has strong specificity and high sensitivity and detects multiple target sequences in one experiment.Compared with other methods,BMB array has great application potential. | Hongming Dong Congli Tang Ziyu He Hongmei Liu Yuyue Xu Hao Huang Gaojian Yang Ziqi Xiao Song Li Yan Deng Zhu Chen Hui Chen Zuodong Qin Yasser Perera Negrin Nongyue He | 2020 | Chinese Chemical Letters2020，31，7： | 0 |
| 4 | Ultrasensitive electrochemical immunosensor of carcinoembryonic antigen based on gold-label silver-stain signal amplification显示文摘A novel gold-label silver-stain electrochemical immunosensor was developed based on polythioninegold nanoparticles(PTh-Au) modified glassy carbon electrode(GCE) as a platform and secondary antibody labeled Au NPs(Ab_2-Au) as immumoprobe for carcinoembryonic antigen(CEA) detection. The sandwich-type biosensor adopted anodic stripping voltammetry to detect silver stripping signal when the Ab_2-Au of the formed immunocomplexes were stained with silver. The optimized detection conditions were investigated. The effect of different electrochemical responses at various concentrations of CEA was checked by anodic stripping voltammetry. This immunosensor showed a low detection limit of 0.055 ng/mL and a wide linear calibration of 0.1-120 ng/mL(R^2=0.99856). Moreover, this immunoassay also existed the advantages of good reproducibility, stability and selectivity. Thus, this immunosensing protocol may provide a potential application for effective clinical detection of CEA. | Gaojian Yang Yuxuan Lai Ziqi Xiao Congli Tang Yan Deng | 2018 | Chinese Chemical Letters2018，29，12： | 0 |
| 5 | Study on MIP Technology for Production of EUROⅣClean Gasoline 1.Analysis of Rules for Transformation of Sulfur Compounds and Factors Influencing Sulfur Content in MIP Naphtha显示文摘The rules of MIP reactions for catalytic cracking of sulfur compounds and its influence on the sulfur content in the MIP naphtha were studied.The mam factors influencing the sulfur content in the MIP naphtha were thought to be the sulfur content of feedstock and were closely related with the olefin content of naphtha.Taking into account the characteristic features of MIP process,the methods for reducing the sulfur content in the MIP naphtha were comprised of decreasing the sulfur content of feedstock by hydrotreating and decreasing the olefin content of naphtha through promoting hydrogen transfer reactions.Therefore,the EuroⅣclean gasoline with low sulfur content and low olefin content could be obtained directly through the MIP technology. | Tang Jinlian Xu Youhao Cheng Congli Wang Xieqing (Research Institute of Petroleum Processing,SINOPEC,Beijing 100083,China) | 2009 | China Petroleum Processing & Petrochemical Technology2009，11，4： | 0 |
