Durable metal-enhanced fluorescence flexible platform by in-situ growth of micropatterned Ag nanospheres

Journal of Materials Science & Technology 2021年第10期69卷 89-95页

作者： Xiangfu Liu Rongwen Wang Jinming Ma jibin zhang Pengfei Jiang Yao Wang Guoli Tu Wuhan National Laboratory for Optoelectronics Huazhong University of Science and Technology1037 Luoyu RoadWuhan 430074China

Here, we demonstrate an in-situ growth of micropatterned silver nanospheres(Ag NS) array on transparent polyimide(PI), namely PI-Ag substrate, applied as a flexible platform for metal-enhanced fluorescence(MEF). The scheme proposed here can easily control the grid formation of Ag NSs and the particle size inside, thus achieving patterned fluorescence imaging and MEF efficiency optimization. Meanwhile, the magnitude of enhanced intensity, relying on the distance between Ag NSs and emissive molecules, was systematically investigated by exploring diverse polyethyleneimine(PEI) spacer thickness. Consequently,an optimal enhancement factor of 7.9 and a pattern of grid fluorescence imaging was obtained with an insertion of 10 nm PEI on the PI-Ag(25 nm) platform. Moreover, owing to robust adhesion between Ag NSs and PI film by in-situ growth, this flexible PI-Ag MEF platform maintained a stable MEF efficiency even after taking mechanical bending for 1000 cycles. This new surface-confined micropatterned Ag NSs PI film provides a promising candidate in design flexible MEF platforms for future analytical and clinical sensing applications.

Porous structure Li[Ni1/3Co1/3Mn1/3]O2 has been synthesized via a facile carbonate co-precipitation method using Li2CO3 as template and lithium-source. The physical and electrochemical properties of the materials were examined by many characterizations including TGA, XRD, SEM, EDS, TEM, BET, CV, EIS and galvanostatic charge-discharge cycling. The results indicate that the as-synthesized materials by this novel method own a well-ordered layered structure a-NaFeO2 [space group： R-3m（166）], porous morphology, and an average primary particle size of about 150 nm. The porous material exhibits larger specific surface area and delivers a high initial capacity of 169.9 mAh·g^-1 at 0.1 C （1 C=180 mA·g ^-1） between 2.7 and 4.3 V, and 126.4, 115.7 mAh.g 1 are still respectively reached at high rate of 10 C and 20 C. After 100 charge-discharge cycles at 1 C, the capacity retention is 93.3%, indicating the excellent cycling stability.

Human immunodeficiency virus-1 （HIV-1）encodes 15 viral proteins. Protein-protein interactions play a large role in the function of these proteins. In this study, we attempted to identify novel interactions between the HIV-1 proteins to better understand the role played by viral protein-protein interactions in the life cycle of HIV-I. Genes encoding the 15 viral proteins from the HIV-1 strain AD8 were inserted into the plasmids of a yeast two-hybrid system. By screening 120 pairs of proteins, interactions between seven pairs were found. This led to the discovery of an interaction between the HIV-1 proteins integrase （IN） and glycoprotein 41 （gp41）, which was confirmed by both co-immunoprecipitation （Co-IP） assays and fluorescence resonance energy transfer （FRET） imaging in live cells. In addition, it was found that the amino acids at positions 76-100 of gp41 are required for it to bind to IN. Deletion of this region from gp41 prevented its interaction with IN and reduced the production of HIV-1 in 293T cells. This study provides new information on HIV-1 protein-protein interactions which improves the understanding of the biological functions of gp41 and IN during the virus life cycle.

Objective： To explore the application of MR perfusion-weighted imaging （PWI） in the benign and malignant prostate diseases, and evaluate the correlations of PWl features with vascular endothelial growth factor （VEGF） and microvessel density （MVD）. Methods： Seventy-four consecutive patients who were diagnosed clinically for the prostate diseases, including forty-four cases with benign prostate hyperplasia and thirty cases with prostatic cancer proved pathologically, were examined by PWI. MVD and VEGF were stained with immunohistochemical methods. Some parameters of PWl, including the steepest slope of signal intensity-time curve （SSmax） and the change in relaxation rate （ΔR2^＊ peak） at lesions, were analyzed. Correlation analysis was used to determine the relationship between the results of PWl and immunohistochemistry. Results：（1） In the benign prostate hyperplasia （BPH）, SSmax and ΔR2^＊ peak of perfusion curve were 34.2 ± 2.9 and 1.49 ± 0.11, respectively; however, in the prostatic cancer （Pca）, they were 58.6± 4.8 and 3.18 ±0.49 respectively; there were statistical differences （t = 2.16 and 2.31, P 〈 0.05）. （2） The VEGF and MVD expressions of thirty Pca patients were significantly higher than those of forty-four BPH patients （x2 = 28.64, P 〈 0.01; t = 21.2, P 〈 0.01）. MVD expressions of Pca and BPH groups showed positive associations with VEGF expressions （P 〈 0.01）. On MR perfusion-weighted imaging, SSmax and ΔR2^＊ peak showed associations with MVD and VEGF expressions （P 〈 0.01）. Conclusion： On MR perfusion-weighted imaging, SSmax and ΔR2^＊ peak can reflect MVD and VEGF expression levels in the benign and malignant prostate diseases and might be implied the tumor angiogenesis so as to distinguish benign from malignant and provide the important information for the surgeon to diagnose and treat the prostatic diseases.

液池内的孔板鼓泡是安全壳内气体过滤排放过程中的重要现象。过滤过程中,孔板鼓泡体积直接影响气泡的上升速度与气液接触面积,因此是影响过滤器过滤效率的重要参数之一。随着过滤的进行,液池内滞留的气溶胶可能成为孔板鼓泡体积的影响因素之一。本文采用可视化实验,对含BaSO4和TiO2气溶胶液池内的孔板鼓泡过程进行研究,观察和分析孔板鼓泡体积的变化规律,进而获取气溶胶对孔板鼓泡体积的影响机制。研究表明,高温液池和TiO2会使得生成气泡体积增加,添加BaSO4的影响并不明显,实验还发现了生成气泡顶部含“小气腔”的情况,表面张力及“小气腔”的变化是气泡体积改变的主要机制。

作者： Ye Yuan Dianbing Wang jibin zhang Ji Liu Jian Chen Xian-En zhang National Laboratory of Biomacromolecules CAS Center for Excellence in Biomacromolecules Institute of Biophysics Chinese Academy of Sciences College of Life Science and Technology Huazhong Agricultural University College of Life Science Hubei University

The objective of the study was to elucidate optical characteristics of the chromophore structures of fluorescent proteins. Raman spectra of commonly used GFP-like fluorescent proteins（FPs） with diverse emission wavelengths（green, yellow, cyan and red）, including the enhanced homogenous FPs EGFP,EYFP, and ECFP（from jellyfish） as well as m Neptune（from sea anemone） were measured. High-quality Raman spectra were obtained and many marker bands for the chromophore of the FPs were identified via assignment of Raman spectra bands. We report the presence of a positive linear correlation between the Raman band shift of C;=C;and the excitation energy of FPs, demonstrated by plotting absorption maxima(cm;) against the position of the Raman band C;=C;in EGFP, ECFP, EYFP, the anionic chromophore and the neutral chromophore. This study revealed new Raman features in the chromophores of the observed FPs, and may contribute to a deeper understanding of the optical properties of FPs.

ON THERMAL HISTORY OF TIANSHAN GEOSYNCLINE ACCORDING TO THE DATA ON K-Ar DATING OF EASTERN TIANSHAN

引用

Science in China,Ser.B 1982年第11期25卷 1213-1226页

作者：胡霭琴章振根张积斌杨昇祖 Institute of Geochemistry Academia Sinica Guiyang Prospecting Team No. 704 of Xinjiang Geologic Prospecting Corporation Ministry of Metallurgical Industry

On the basis of the data of 45 K-Ar ages in the Eastern Tianshan, Uygur AutonomousRegion of Xinjiang, China, and the geological environment, the following conclusions aregiven. The Tianshan Hercynian geosyncline had passed through about 200 m.y. before itsformation, and it was in the late Kercynian at about 234.9±20 m.y. ago. The Yenshanmagmatism in this region has been first verified by the authors, and its K-Ar age is esti-mated at 196.6-157.6±20 m.y. The Hercynian magmatic activities may be divided intotwo substages: the early substage is of 300-350±20 m.y., and the later is of 230±20 m.y. By using the results of the determination of the ages, the thermal history ofTianshan geosyncline is preliminarily discussed.
