| 2 | Synthesis of Fe_3O_4@SiO_2@polymer nanoparticles for controlled drug release显示文摘Novel multifunctional nanoparticles containing a magnetic Fe3O4@SiO2 sphere and a biocompatible block copolymer poly(ethylene glycol)-b-poly(aspartate)(PEG-b-PAsp) were prepared.The silica coated on the superparamagnetic core was able to achieve a magnetic dispersivity,as well as to protect Fe3O4 against oxidation and acid corrosion.The PAsp block was grafted to the surface of Fe3O4@SiO2 nanoparticles by amido bonds,and the PEG block formed the outermost shell.The anticancer agent doxorubicin(DOX) was loaded into the hybrid nanoparticles via an electrostatic interaction between DOX and PAsp.The release rate of DOX could be adjusted by the pH value. | WU ChengLin,HE Huan,GAO HongJun,LIU Gan,MA RuJiang,AN YingLi & SHI LinQi Key Laboratory of Functional Polymer Materials,Ministry of Education Institute of Polymer Chemistry,Nankai University,Tianjin 300071,China | 2010 | Science China Chemistry2010，53，3： | 9 |
| 3 | Injectable dual glucose-responsive hydrogel-micelle composite for mimicking physiological basal and prandial insulin delivery显示文摘For type 1 and advanced type 2 diabetic patients, insulin replacement therapy with simulating on-demand prandial and basal insulin secretion is the best option for optimal glycemic control. However, there is no insulin delivery system yet could mimic both controlled basal insulin release and rapid prandial insulin release in response to real-time blood glucose changes. Here we reported an artificial insulin delivery system, mimicking physiological basal and prandial insulin secretion, to achieve real-time glycemic control and reduce risk of hypoglycemia. A phenylboronic acid(PBA)/galactosyl-based glucose-responsive insulin delivery system was prepared with insulin-loaded micelles embedded in hydrogel matrix. At the hyperglycemic state, both the hydrogel and micelles could swell and achieve rapid glucose-responsive release of insulin, mimicking prandial insulin secretion.When the glucose level returned to the normal state, only the micelles partially responded to glucose and still released insulin gradually. The hydrogel with increased crosslinking density could slow down the diffusion speed of insulin inside, resulting in controlled release of insulin and simulating physiological basal insulin secretion. This hydrogel-micelle composite insulin delivery system could quickly reduce the blood glucose level in a mouse model of type 1 diabetes, and maintain normal blood glucose level without hypoglycemia for about 24 h. This kind of glucose-responsive hydrogel-micelle composite may be a promising candidate for delivery of insulin in the treatment of diabetes. | Juan Lv Gang Wu Ying Liu Chang Li Fan Huang Yumin Zhang Jinjian Liu Yingli An Rujiang Ma Linqi Shi | 2019 | Science China Chemistry2019，62，5： | 5 |
| 4 | Optic and catalytic properties of gold nanoparticles tuned by homopolymers显示文摘Gold nanoparticles (GNs) are prepared through in situ reduction using NaBH4 in the presence of homopolymer PDMAEMA. The sizes of the GNs can be adjusted by alternating the molar ratio of gold to DMAEMA. Pure PDMAEMA aqueous solution shows a phase-transition at 50℃ at pH 10 and 25℃ at pH 14, while PDMAEMA-supported GNs aqueous solution shows a phase-transition at 47℃ at pH 10 because of the increasing hydrophobic property resulting from GNs. Due to the pH and tempera-ture-responsible characteristics of PDMAEMA, the resulting PDMAEMA-supported GNs exhibit pH adjustable temperature-responsive characteristics in optic and catalytic aspects. Under an acidic condi-tion (pH 2), the GNs show unchanged surface Plasmon absorbance with a peak of 518 nm in a tem-perature range from 20 to 65℃. Under a basic condition (pH 10), the GNs first show the same absorb-ance with a peak at 518 nm in a temperature range from 20 to 40℃, and then the absorbance red shifts from 518 to 545 nm as temperature increases from 40 to 65℃. When the GNs are used as catalysts to catalyze the reduction of p-nitrophenol, the catalytic activity can be adjusted by changing the permeation of reactants in the PDMAEMA layer at low and high temperatures, respectively. | CHEN Xi ZHAO DongYun ZHAO LiZhi AN YingLi MA RuJiang SHI LinQi HE QiJun CHEN Li | 2009 | Science China Chemistry2009，52，9： | 3 |

| 12 | In-biofilm generation of nitric oxide using a magnetically-targetable cascade-reaction container for eradication of infectious biofilms显示文摘Cascade-reaction chemistry can generate reactive-oxygen-species that can be used for the eradication of infectious biofilms.However,suitable and sufficient oxygen sources are not always available near an infection site,while the reactive-oxygen-species generated are short-lived.Therefore,we developed a magnetic cascade-reaction container composed of mesoporous Fe_(3)O_(4)@SiO_(2) nanoparticles containing glucose-oxidase and L-arginine for generation of reactive-oxygen-species.Glucose-oxidase was conjugated with APTES facilitating coupling to Fe_(3)O_(4)@SiO_(2) nanoparticles and generation of H_(2)O_(2) from glucose.L-arginine was loaded into the nanoparticles to generate NO from the H_(2)O_(2) generated.Using an externally-applied magnetic field,cascade-reaction containers could be homogeneously distributed across the depth of an infectious biofilm.Cascade-reaction containers with coupled glucose-oxidase were effective in killing planktonic,Gram-positive and Gram-negative bacteria.Additional efficacy of the L-arginine based second cascade-reaction was only observed when H_(2)O_(2) as well as NO were generated in-biofilm.In vivo accumulation of cascade-reaction containers inside abdominal Staphylococcus aureus biofilms upon magnetic targeting was observed real-time in living mice through an implanted,intra-vital window.Moreover,vancomycin-resistant,abdominal S.aureus biofilms could be eradicated consuming solely endogenous glucose,without any glucose addition.Herewith,a new,non-antibiotic-based infection-control strategy has been provided,constituting a welcome addendum to the shrinking clinical armamentarium to control antibiotic-resistant bacterial infections. | Guang Yang Da-Yuan Wang Yong Liu Fan Huang Shuang Tian Yijin Ren Jianfeng Liu Yingli An Henny C.van der Mei Henk J.Busscher Linqi Shi | 2022 | Bioactive Materials2022，7，8： | 0 |
| 13 | Polymorphism of the 86th amino acid in CX26 protein and hereditary deafness显示文摘Objective: To investigate the membrane localization function of the CX26 protein when its 86 th amino acid is Thr, Ser or Arg, and its relations to deafness.Methods: CX26-GFP protein with either Thr, Ser or Arg as the 86 th amino acid was expressed in mouse SGN cells via the GFP fusion type lentivirus expression system. The membrane localization of the fusion protein was observed under a fluorescence microscope.Results: The mutated protein of CX26 T86 S was localized to cell membrane and form gap conjunction structures, showing no difference to the wild type CX26 protein(with Thr as the 86 th amino acid). However, the gap conjunction structure disappeared when the mutation was CX26T86 A.Conclusion: These results indicate that the CX26 T86 R mutation may be a cause of hearing loss, but CX26 T86 S as a non-pathogenic polymorphism mutation does not affect functions of the CX26 protein. The results are in accordance with the results of clinical screening. | Xi Shi Shiwei Qiu Fendong Yan Lizhang Shi Yili Xuan Wei Zhuang Yingli Bei Hanli Yao Na Yuan Mingyang Shi Yuehua Qiao | 2016 | Journal of Otology2016，11，2： | 0 |
| 14 | Parthenolide reveals an allosteric mode to inhibit the delSGylation activity of SARS-CoV-2 papain-like protease显示文摘The coronavirus papain-like protease(PLpro)of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)is responsible for viral polypeptide cleavage and the deISGylation of interferon-stimulated gene 15(ISG15),which enable it to participate in virus replication and host innate immune pathways.Therefore,PLpro is considered an attractive antiviral drug target.Here,we show that parthenolide,a germacrane sesquiterpene lactone,has SARS-CoV-2 PLpro inhibitory activity.Parthenolide covalently binds to Cys-191 or Cys-194 of the PLpro protein,but not the Cys-111 at the PLpro catalytic site.Mutation of Cys-191 or Cys-194 reduces the activity of PLpro.Molecular docking studies show that parthenolide may also form hydrogen bonds with Lys-192,Thr-193,and Gln-231.Furthermore,parthenolide inhibits the deISGylation but not the deubiquitinating activity of PLpro in vitro.These results reveal that parthenolide inhibits PLpro activity by allosteric regulation. | Zhihui Zou Huizhuang Shan Demeng Sun Li Xia Yulong Shi Jiahui Wan Aiwu Zhou Yunzhao Wu Hanzhang Xu Hu Lei Zhijian Xu Yingli Wu | 2022 | Acta Biochimica et Biophysica Sinica2022，54，8： | 0 |

| 16 | Analytical transient phase change heat transfer model of wearable electronics with a thermal protection substrate显示文摘As thermal protection substrates for wearable electronics,functional soft composites made of polymer materials embedded with phase change materials and metal layers demonstrate unique capabilities for the thermal protection of human skin.Here,we develop an analytical transient phase change heat transfer model to investigate the thermal performance of a wearable electronic device with a thermal protection substrate.The model is validated by experiments and the finite element analysis(FEA).The effects of the substrate structure size and heat source power input on the temperature management efficiency are investigated systematically and comprehensively.The results show that the objective of thermal management for wearable electronics is achieved by the following thermal protection mechanism.The metal thin film helps to dissipate heat along the in-plane direction by reconfiguring the direction of heat flow,while the phase change material assimilates excessive heat.These results will not only promote the fundamental understanding of the thermal properties of wearable electronics incorporating thermal protection substrates,but also facilitate the rational design of thermal protection substrates for wearable electronics. | Yingli SHI Junyun JI Yafei YIN Yuhang LI Yufeng XING | 2020 | Applied Mathematics and Mechanics(English Edition)2020，41，11： | 0 |

The effects of the ion synthesis mechanism, chemical stoichiometry, fabrication method, and doping content on the magnetic properties and microstructure of the thin films have been analyzed.The films formed between 75℃ and 90℃ by spray-spin-heating-coating methods was discovered with fine grain size of about 21 nm, high saturation magnetization (4πMs) of about 6.5 kGs, coercivity of about 9.8 Oe, as well as initial permeability of about 14.0. These films can be widely used in radio-frequency integrated circuit devices. | Yulan JING, Huaiwu ZHANG, lijun JIA, Yu SHI and Yingli LIUInstitute of Information and Materials, University of Electronic Science and Technology of China, Chengdu 610054, China | 2004 | Journal of Materials Science & Technology2004，20，1： | 0 |
| 18 | Synaptic transistor with multiple biological functions based on metal-organic frameworks combined with the LIF model of a spiking neural network to recognize temporal information显示文摘Spiking neural networks(SNNs)have immense potential due to their utilization of synaptic plasticity and ability to take advantage of temporal correlation and low power consumption.The leaky integration and firing(LIF)model and spike-timing-dependent plasticity(STDP)are the fundamental components of SNNs.Here,a neural device is first demonstrated by zeolitic imidazolate frameworks(ZIFs)as an essential part of the synaptic transistor to simulate SNNs.Significantly,three kinds of typical functions between neurons,the memory function achieved through the hippocampus,synaptic weight regulation and membrane potential triggered by ion migration,are effectively described through short-term memory/long-term memory(STM/LTM),long-term depression/long-term potentiation(LTD/LTP)and LIF,respectively.Furthermore,the update rule of iteration weight in the backpropagation based on the time interval between presynaptic and postsynaptic pulses is extracted and fitted from the STDP.In addition,the postsynaptic currents of the channel directly connect to the very large scale integration(VLSI)implementation of the LIF mode that can convert high-frequency information into spare pulses based on the threshold of membrane potential.The leaky integrator block,firing/detector block and frequency adaptation block instantaneously release the accumulated voltage to form pulses.Finally,we recode the steadystate visual evoked potentials(SSVEPs)belonging to the electroencephalogram(EEG)with filter characteristics of LIF.SNNs deeply fused by synaptic transistors are designed to recognize the 40 different frequencies of EEG and improve accuracy to 95.1%.This work represents an advanced contribution to brain-like chips and promotes the systematization and diversification of artificial intelligence. | Qinan Wang Chun Zhao Yi Sun Rongxuan Xu Chenran Li Chengbo Wang Wen Liu Jiangmin Gu Yingli Shi Li Yang Xin Tu Hao Gao Zhen Wen | 2023 | Microsystems & Nanoengineering2023，9，4： | 0 |
| 19 | Flexible radio-frequency micro electro-mechanical switch towards the applications of satellite communications显示文摘This paper presents a flexible radio-frequency microelectromechanical system(RF MEMS)switch integrated on cyclo-olefin polymer(COP)substrate using a modified surface MEMS processing technology,which could be used in the 17-19 GHz frequency band of satellite communication.Through systematic simulation analysis,it is found that flexible RF MEMS switch can achieve certain bending radius by miniaturizing the electronic dimension,without degrading the RF performance.It is demonstrated that the RF characteristics of flexible RF MEMS switch with special anchor structural design,fabricated by modified surface MEMS processing,are not sensitive to bending deformation under the curvature of 0 mm^(-1),0.05 mm^(-1),0.10 mm^(-1).Furthermore,the range of bending curvature which will affect the RF characteristics is given through systematic simulation.The flexible RF MEMS switch with high process compatibility and stable RF performance is believed to be promising candidates for future microwave communications and other consumer electronics. | Yingli Shi Chao Zhou Zibo Cao Yurong He Jingwen Guo Chunxin Li Qianhong Wu Kui Liang Yanzhao Li Yuan Lin | 2022 | npj Flexible Electronics2022，6，1： | 0 |
