| 1 | Nano-Graphene Oxide for Cellular Imaging and Drug Delivery显示文摘Two-dimensional graphene offers interesting electronic,thermal,and mechanical properties that are currently being explored for advanced electronics,membranes,and composites.Here we synthesize and explore the biological applications of nano-graphene oxide(NGO),i.e.,single-layer graphene oxide sheets down to a few nanometers in lateral width.We develop functionalization chemistry in order to impart solubility and compatibility of NGO in biological environments.We obtain size separated pegylated NGO sheets that are soluble in buffers and serum without agglomeration.The NGO sheets are found to be photoluminescent in the visible and infrared regions.The intrinsic photoluminescence(PL)of NGO is used for live cell imaging in the near-infrared(NIR)with little background.We found that simple physisorption viaπ-stacking can be used for loading doxorubicin,a widely used cancer drug onto NGO functionalized with antibody for selective killing of cancer cells in vitro.Owing to its small size,intrinsic optical properties,large specifi c surface area,low cost,and useful non-covalent interactions with aromatic drug molecules,NGO is a promising new material for biological and medical applications. | Xiaoming Sun Zhuang Liu Kevin Welsher Joshua Tucker Robinson Andrew Goodwin Sasa Zaric Hongjie Dai | 2008 | Nano Research2008，1，3： | 118 |

| 3 | TiO_(2) Nanocrystals Grown on Graphene as Advanced Photocatalytic Hybrid Materials显示文摘A graphene/TiO_(2) nanocrystals hybrid has been successfully prepared by directly growing TiO_(2) nanocrystals on graphene oxide(GO)sheets.The direct growth of the nanocrystals on GO sheets was achieved by a two-step method,in which TiO_(2) was first coated on GO sheets by hydrolysis and crystallized into anatase nanocrystals by hydrothermal treatment in the second step.Slow hydrolysis induced by the use of EtOH/H2O mixed solvent and addition of H2SO4 facilitates the selective growth of TiO_(2) on GO and suppresses growth of free TiO_(2) in solution.The method offers easy access to the GO/TiO_(2) nanocrystals hybrid with a uniform coating and strong interactions between TiO_(2) and the underlying GO sheets.The strong coupling gives advanced hybrid materials with various applications including photocatalysis.The prepared graphene/TiO_(2) nanocrystals hybrid has superior photocatalytic activity to other TiO_(2) materials in the degradation of rhodamine B,showing an impressive three-fold photocatalytic enhancement over P25.It is expected that the hybrid material could also be promising for various other applications including lithium ion batteries,where strong electrical coupling to TiO_(2) nanoparticles is essential. | Yongye Liang Hailiang Wang Hernan Sanchez Casalongue Zhuo Chen Hongjie Dai | 2010 | Nano Research2010，3，10： | 57 |
| 4 | Carbon Nanotubes in Biology and Medicine:In vitro and in vivo Detection,Imaging and Drug Delivery显示文摘Carbon nanotubes exhibit many unique intrinsic physical and chemical properties and have been intensively explored for biological and biomedical applications in the past few years.In this comprehensive review,we summarize the main results from our and other groups in this field and clarify that surface functionalization is critical to the behavior of carbon nanotubes in biological systems.Ultrasensitive detection of biological species with carbon nanotubes can be realized after surface passivation to inhibit the non-specific binding of biomolecules on the hydrophobic nanotube surface.Electrical nanosensors based on nanotubes provide a label-free approach to biological detection.Surface-enhanced Raman spectroscopy of carbon nanotubes opens up a method of protein microarray with detection sensitivity down to 1 fmol/L.In vitro and in vivo toxicity studies reveal that highly water soluble and serum stable nanotubes are biocompatible,nontoxic,and potentially useful for biomedical applications.In vivo biodistributions vary with the functionalization and possibly also size of nanotubes,with a tendency to accumulate in the reticuloendothelial system(RES),including the liver and spleen,after intravenous administration.If well functionalized,nanotubes may be excreted mainly through the biliary pathway in feces.Carbon nanotube-based drug delivery has shown promise in various In vitro and in vivo experiments including delivery of small interfering RNA(siRNA),paclitaxel and doxorubicin.Moreover,single-walled carbon nanotubes with various interesting intrinsic optical properties have been used as novel photoluminescence,Raman,and photoacoustic contrast agents for imaging of cells and animals.Further multidisciplinary explorations in this field may bring new opportunities in the realm of biomedicine. | Zhuang Liu Scott Tabakman Kevin Welsher Hongjie Dai | 2009 | Nano Research2009，2，2： | 50 |

| 7 | High-entropy ceramics:Present status,challenges,and a look forward显示文摘High-entropy ceramics (HECs) are solid solutions of inorganic compounds with one or more Wyckoff sites shared by equal or near-equal atomic ratios of multi-principal elements.Although in the infant stage,the emerging of this new family of materials has brought new opportunities for material design and property tailoring.Distinct from metals,the diversity in crystal structure and electronic structure of ceramics provides huge space for properties tuning through band structure engineering and phonon engineering.Aside from strengthening,hardening,and low thermal conductivity that have already been found in high-entropy alloys,new properties like colossal dielectric constant,super ionic conductivity,severe anisotropic thermal expansion coefficient,strong electromagnetic wave absorption,etc.,have been discovered in HECs.As a response to the rapid development in this nascent field,this article gives a comprehensive review on the structure features,theoretical methods for stability and property prediction,processing routes,novel properties,and prospective applications of HECs.The challenges on processing,characterization,and property predictions are also emphasized.Finally,future directions for new material exploration,novel processing,fundamental understanding,in-depth characterization,and database assessments are given. | Huimin XIANG Yan XING Fu-zhi DAI Hongjie WANG Lei SU Lei MIAO Guojun ZHANG Yiguang WANG Xiwei QI Lei YAO Hailong WANG Biao ZHAO Jianqiang LI Yanchun ZHOU | 2021 | Journal of Advanced Ceramics2021，10，3： | 28 |
| 8 | High Performance In Vivo Near-IR (>1 μm) Imaging and Photothermal Cancer Therapy with Carbon Nanotubes显示文摘Short single-walled carbon nanotubes(SWNTs)functionalized by PEGylated phospholipids are biologically non-toxic and long-circulating nanomaterials with intrinsic near infrared photoluminescence(NIR PL),characteristic Raman spectra,and strong optical absorbance in the near infrared(NIR).This work demonstrates the first dual application of intravenously injected SWNTs as photoluminescent agents for in vivo tumor imaging in the 1.0-1.4μm emission region and as NIR absorbers and heaters at 808 nm for photothermal tumor elimination at the lowest injected dose(70μg of SWNT/mouse,equivalent to 3.6 mg/kg)and laser irradiation power(0.6 W/cm2)reported to date.Ex vivo resonance Raman imaging revealed the SWNT distribution within tumors at a high spatial resolution.Complete tumor elimination was achieved for large numbers of photothermally treated mice without any toxic side effects after more than six months post-treatment.Further,side-by-side experiments were carried out to compare the performance of SWNTs and gold nanorods(AuNRs)at an injected dose of 700μg of AuNR/mouse(equivalent to 35 mg/kg)in NIR photothermal ablation of tumors in vivo.Highly effective tumor elimination with SWNTs was achieved at 10 times lower injected doses and lower irradiation powers than for AuNRs.These results suggest there are significant benefits of utilizing the intrinsic properties of biocompatible SWNTs for combined cancer imaging and therapy. | Joshua T.Robinson Kevin Welsher Scott M.Tabakman Sarah P.Sherlock Hailiang Wang Richard Luong Hongjie Dai | 2010 | Nano Research2010，3，11： | 20 |
| 9 | Biological imaging without autofluorescence in the second near-infrared region显示文摘Fluorescence imaging is capable of acquiring anatomical and functional infor- mation with high spatial and temporal resolution. This imaging technique has been indispensable in biological research and disease detection/diagnosis. Imaging in the visible and to a lesser degree, in the near-infrared (NIR) regions below 900 nm, suffers from autofluorescence arising from endogenous fluorescent molecules in biological tissues. This autofluorescence interferes with fluorescent molecules of interest, causing a high background and low detection sensitivity. Here, we report that fluorescence imaging in the 1,500-1,700-nm region (termed "NIR-IIb") under 808-nm excitation results in nearly zero tissue autofluorescence, allowing for background-free imaging of fluorescent species in otherwise notoriously autofluorescent biological tissues, including liver. Imaging of the intrinsic fluorescence of individual fluorophores, such as a single carbon nanotube, can be readily achieved with high sensitivity and without autofluorescence background in mouse liver within the 1,500-1,700-nm wavelength region. | Shuo Diao Guosong Hong Alexander L.

| 10 | A mini-review on rare-earth down-conversion nanoparticles for NIR-II imaging of biological systems显示文摘Rare-earth(RE)based luminescent probes exhibit rich optical properties including upconversion and down-conversion luminescence spanning a broad spectral range from 300 to 3,000 nm,and have generated great scientific and practical interest from telecommunication to biological imaging.While upconversion nanoparticles have been investigated for decades,down-conversion luminescence of RE-based probes in the second near-infrared(NIR-II,1,000-1,700 nm)window for in vivo biological imaging with sub-centimeter tissue penetration and micrometer image resolution has come into light only recently.In this review,we present recent progress on RE-based NIR-II probes for in vivo vasculature and molecular imaging with a focus on Er3+-based nanoparticles due to the down-conversion luminescence at the long-wavelength end of the NIR-II window(NIR-IIb,1,500-1,700 nm).Imaging in NIR-IIb is superior to imaging with organic probes such as ICG and IRDye800 in the^800 nm NIR range and the 1,000-1,300 nm short end of NIR-II range,owing to minimized light scattering and autofluorescence background.Doping by cerium and other ions and phase engineering of Er^3+-based nanoparticles,combined with surface hydrophilic coating optimization can afford ultrabright,biocompatible NIR-IIb probe towards clinical translation for human use.The Nd^3+-based probes with NIR-II emission at 1,050 and 1,330 nm are also discussed,including Nd^3+doped nanocrystals and Nd^3+-organic ligand complexes.This review also points out future directions for further development of multi-functional RE NIR-II probes for biological imaging. | Yeteng Zhong Hongjie Dai | 2020 | Nano Research2020，13，5： | 11 |
| 11 | Multiplexed Five-Color Molecular Imaging of Cancer Cells and Tumor Tissues with Carbon Nanotube Raman Tags in the Near-Infrared显示文摘Single-walled carbon nanotubes(SWNTs)with five different C13/C12 isotope compositions and well-separated Raman peaks have been synthesized and conjugated to five targeting ligands in order to impart molecular specificity.Multiplexed Raman imaging of live cells has been carried out by highly specific staining of cells with a five-color mixture of SWNTs.Ex vivo multiplexed Raman imaging of tumor samples uncovers a surprising up-regulation of epidermal growth factor receptor(EGFR)on LS174T colon cancer cells from cell culture to in vivo tumor growth.This is the first time five-color multiplexed molecular imaging has been performed in the near-infrared(NIR)region under a single laser excitation.Near zero interfering background of imaging is achieved due to the sharp Raman peaks unique to nanotubes over the low,smooth autofluorescence background of biological species. | Zhuang Liu Scott Tabakman Sarah Sherlock Xiaolin Li Zhuo Chen Kaili Jiang Shoushan Fan Hongjie Dai | 2010 | Nano Research2010，3，3： | 11 |
| 12 | WS2 nanoflakes from nanotubes for electrocatalysis显示文摘为切开的水的下一代的催化剂向可更新的氢经济是关键的。MoS2 和 WS2 在边地点与高催化的活动代表地球丰富的、高贵金属阴极选择。在他们的开发的一挑战是这些材料到 nanostructure 以便通过另外的边地点的创造完成增加的性能。在这个工作,我们表明一条简单线路用 sonochemical 脱落形成 nanostructured-WS2 在 WS2 nanotubes 打破夹层和 intralayer 契约。产生很少层 nanoflakes 是与边地点的高密度宽的 100 nm。WS2 nanoflakes 为氢进化反应作为阴极被利用(她的) 并且展览上级性能到 WS2 nanotubes 和体积粒子与一个更低的发作潜力,更浅的 Tafel 斜坡和增加的当前的密度。未来工作可以采用进一步改进 electrocatalytic 活动的极端小的 nanoflakes,掺杂物原子,或 graphene 混血儿。 | Charina L.

| 13 | Aligned Graphene Nanoribbons and Crossbars from Unzipped Carbon Nanotubes显示文摘Aligned graphene nanoribbon (GNR) arrays have been made by unzipping of aligned single-walled and few-walled carbon nanotube (CNT) arrays. Nanotube unzipping was achieved by a polymer-protected Ar plasma etching method, and the resulting nanoribbon array can be transferred onto any chosen substrate. Atomic force microscope (AFM) imaging and Raman mapping on the same CNTs before and after unzipping confirmed that ~80% of CNTs were opened up to form single layer sub-10 nm GNRs. Electrical devices made from the GNRs (after annealing in H2 at high temperature) showed on/off current (Ion/Ioff) ratios up to 103 at room temperature, suggesting the semiconducting nature of the narrow GNRs. Novel GNR-GNR and GNR-CNT crossbars were fabricated by transferring GNR arrays across GNR and CNT arrays, respectively. The production of such ordered graphene nanoribbon architectures may allow for large scale integration of GNRs into nanoelectronics or optoelectronics. | Liying Jiao Li Zhang Lei Ding Jie Liu Hongjie Dai | 2010 | Nano Research2010，3，6： | 9 |
| 14 | Dynamic frequency response from electric vehicles in the Great Britain power system显示文摘With the large penetration of renewable energy,fulfilling the balance between electricity demand and supply is a challenge to the modern power system.According to the UK government,the wind power penetration will reach 30%by the year 2020.The role of electric vehicles(EVs)contributing to frequency response was investigated.A dynamic frequency control strategy which considers the comfort level of vehicle owners was developed for EVs to regulate their power consumption according to the deviation of system frequency.A simulation model of a population of EVs equipped with such controlwas implemented inMatlab/Simulink platform.In this paper,a simplified Great Britain power system model is used to study the contribution of EVs to dynamic frequency control.The case study showed that using EVs as a demand response resource can greatly reduce the frequency deviations.And the rapid response from EVs can help reduce the operation cost of conventional generators. | Jian MENG Yunfei MU Jianzhong WU Hongjie JIA Qian DAI Xiaodan YU | 2015 | Journal of Modern Power Systems and Clean Energy2015，3，2： | 8 |
| 15 | In-situ fabrication of particulate reinforced aluminum matrix composites under high-frequency pulsed electromagnetic field显示文摘Pulsed magnetic field is generated when imposing pulse signal on high-frequency magnetic field. Distribution of the inner magnetic intensity in induction coils tends to be uniform. Furthermore oscillation and disturbance phenomena appear in the melt. In-situ Al2O3 and Al3Zr particulate reinforced aluminum matrix composites have been synthesized by direct melt reaction using Al-Zr(CO3)2 components under a foreign field. The size of reinforced particulates is 2-3 μm. They are well distributed in the matrix. Thermodynamic and kinetic analysis show that high-frequency pulsed magnetic field accelerates heat and mass transfer processes and improves the kinetic condition of in-situ fabrication. | Guirong Li Yutao Zhao Qixun Dai Hongjie Zhang Hongming Wang | 2007 | Journal of University of Science and Technology Beijing2007，14，5： | 8 |

| 18 | A theranostic agent for cancer therapy and imaging in the second nearinfrared window显示文摘Thera no stic nano particles are integrated systems useful for simulta neous diag nosis and imaging guided delivery of therapeutic drugs, with wide ranging pote ntial applicati ons in the clinic. Here we developed a thera no stic nan oparticle (~24 nm size by dynamic light scatteri ng) p-FE-PTX-FA based on polymeric micelle encapsulating an organic dye (FE) fluorescing in the 1,000-1,700 nm second near-infrared (NIR-Ⅱ) window and an an ti-ca ncer drug paclitaxel. Folic acid (FA) was conjugated to the nan oparticles to afford specific binding to molecular folate receptors on muri ne breast can cer 4T1 tumor cells. In vivo, the nan oparticles accumulated in 4T1 tumor through both passive and active targeting effect. Under an 808 nm laser excitation, fluorescence detection above 1,300 nm afforded a large Stokes shift, allowing targeted molecular imaging tumor with high signal to background ratios, reaching a high tumor to normal tissue signal ratio (T/NT) of (20.0±2.3). Further, 4T1 tumors on mice were completed eradicated by paclitaxel released from p-FE-PTA-FA within 20 days of the first injection. Pharmacokinetics and histology studies indicated p-FE-PTX-FA had no obvious toxic side effects to major organs. This represented the first NIR-Ⅱ theranostic age nt developed. | Zhuoran Ma Hao Wan Weizhi Wang Xiaodong Zhang Takaaki Uno Qianglai Yang Jingying Yue Hongpeng Gao Yeteng Zhong Ye Tian Qinchao Sun Yongye Liang Hongjie Dai | 2019 | Nano Research2019，12，2： | 4 |
| 19 | An electrodeposition approach to metal/metal oxide heterostructures for active hydrogen evolution catalysts in near-neutral electrolytes显示文摘Neutral water splitting is attractive for its use of non-corrosive and environmentally friendly electrolytes.However,catalyst development for hydrogen and oxygen evolution remains a challenge under neutral conditions.Here we report a simple electrodeposition and reductive annealing procedure to produce a highly active Ni-Co-Cr metal/metal oxide heterostructured catalyst directly on Ni foam.The resulting electrocatalyst for hydrogen evolution reaction (HER) requires only 198 mV of overpotential to reach 100 mNcm2 in 1 M potassium phosphate (pH =7.4) and can operate for at least two days without significant performance decay.Scanning transmission electron microscopy coupled with electron energy loss spectroscopy (STEM-EELS) imaging reveals a Ni-Co alloy core decorated with blended oxides layers of NiO,CoO and Cr2O3.The metal/metal oxide interfaces are suggested to be responsible for the high HER activity. | Michael J.Kenney Jianan Erick Huang Yong Zhu Yongtao Meng Mingquan Xu Guanzhou Zhu Wei-Hsuan Hung Yun Kuang Mengchang Lin Xiaoming Sun Wu Zhou Hongjie Dai | 2019 | Nano Research2019，12，6： | 4 |
| 20 | Chemical Self-Assembly of Graphene Sheets显示文摘Chemically derived and noncovalently functionalized graphene sheets(GS)were found to self-assemble onto patterned gold structures via electrostatic interactions between the functional groups and the gold surfaces.This afforded regular arrays of single graphene sheets on large substrates,which were characterized by scanning electron microscopy(SEM),Auger microscopy imaging,and Raman spectroscopy.This represents the fi rst time that self-assembly has been used to produce on-substrate and fully-suspended graphene electrical devices.Molecular coatings on the GS were removed by high current“electrical annealing”,which restored the high electrical conductance and Dirac point of the GS.Molecular sensors for highly sensitive gas detection using the self-assembled GS devices are demonstrated. | Hailiang Wang Xinran Wang Xiaolin Li Hongjie Dai | 2009 | Nano Research2009，2，4： | 4 |
