| 1 | Efficacy and safety of a novel anti-HER2 therapeutic antibody RC48 in patients with HER2-overexpressing,locally advanced or metastatic gastric or gastroesophageal junction cancer:a single-arm phase II study显示文摘Background:Current treatment options for human epidermal growth factor receptor 2(HER2)-overexpressing gastric cancer at third-line have shown limited clinical benefit.Further,there is no specific treatment for HER2 immunohistochemistry(IHC)2+and fluorescence in-situ hybridization-negative patients.Here,we report the efficacy and safety of a novel anti-HER2 antibody RC48 for patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer.Methods:Patients with HER2-overexpressing(IHC 2+or 3+),locally advanced or metastatic gastric or gastroesophageal junction cancer who were under at least second-line therapy were eligible and received RC482.5 mg/kg alone every 2 weeks.The primary endpoint was the objective response rate(ORR)assessed by an independent review committee.Secondary endpoints included progressionfree survival(PFS),overall survival(OS),duration of response,time to progression,disease control rate,and safety.Results:Of 179 patients screened,125 were eligible and received RC48 treatment.The ORR was 24.8%(95%confidence interval[CI]:17.5%-33.3%).The median PFS and OS were 4.1 months(95%CI:3.7-4.9 months)and 7.9 months(95%CI:6.7-9.9 months),respectively.The most frequently reported adverse events were decreased white blood cell count(53.6%),asthenia(53.6%),hair loss(53.6%),decreased neutrophil count(52.0%),anemia(49.6%),and increased aspartate aminotransferase level(43.2%).Serious adverse events(SAEs)occurred in 45(36.0%)patients,and RC48-related SAEs were mainly decreased neutrophil count(3.2%).Seven patients had adverse events that led to death were not RC48-related.Conclusions:RC48 showed promising activity with manageable safety,suggesting potential application in patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer who have previously received at least two lines of chemotherapy. | Zhi Peng Tianshu Liu Jia Wei Airong Wang Yifu He Liuzhong Yang Xizhi Zhang Nanfeng Fan Suxia Luo Zhen Li Kangsheng Gu Jianwei Lu Jianming Xu Qingxia Fan Ruihua Xu Liangming Zhang Enxiao Li Yuping Sun Guohua Yu Chunmei Bai Yong Liu Jiangzheng Zeng Jieer Ying Xinjun Liang Nong Xu Chao Gao Yongqian Shu Dong Ma Guanghai Dai Shengmian Li Ting Deng Yuehong Cui Jianmin Fang Yi Ba Lin Shen | 2021 | Cancer Communications2021，41，11： | 29 |

| 3 | Multifunctional ultrasmall Pd nanosheets for enhanced near-infrared photothermal therapy and chemotherapy of cancer显示文摘在红外线附近(NIR ) photothermal 治疗在最近的年里很快速发展了。然而,它的临床的应用程序被许多实际问题妨碍,例如在在 vivo 的肿瘤,高激光力量密度和高 biotoxicity 的低累积。此处,用 ultrasmall Pd nanosheets (SPNS ) 为癌症治疗把化疗与 photothermal 治疗相结合的一个万用的系统被开发了。SPNS 能担任 pH 应答的药搬运人高效地交付纪录影片进癌症房间和肿瘤。在另一方面,在 SPNS 上的纪录影片的同等的装载在肿瘤织物提高它的累积。我们能高效地因此用低紧张的激光放射切除肿瘤。与 ultrasmall 尺寸(4.4 nm ) ,重要地,有减少的谷胱甘肽(GSH ) 的 SPNS surface-functionalized 能通过肾的系统从身体被清除进尿。这癌症治疗学的 nanosystem,展出重要 synergistic 效果和低全身的毒性,为临床的应用程序有大潜力。 | Shaoheng Tang Mei Chen Nanfeng Zheng | 2015 | Nano Research2015，8，1： | 14 |
| 4 | A vicinal effect for promoting catalysis of Pd1/TiO2:supports of atomically dispersed catalysts play more roles than simply serving as ligands显示文摘Atomically dispersing metal atoms on supports has been emerging as an effective strategy to maximize the atom utilization of metals for catalysis. However, due to the lack of effective tools to characterize the detailed structure of metal-support interface, the chemical functions of supports in atomically dispersed metal catalysts are hardly elucidated at the molecular level. In this work, an atomically dispersed Pd_1/TiO_2 catalyst with Ti(Ⅲ) vicinal to Pd is prepared and used to demonstrate the direct involvement of metal atoms on support in the catalysis of dispersed metal atoms. Systematic studies reveal that the Ti(Ⅲ)-O-Pd interface facilitates the activation of O_2 into superoxide(O_2^-), thus promoting the catalytic oxidation. The catalyst exhibits the highest CO turn-over frequency among ever-reported Pd-based catalysts,and enhanced catalysis in the combustion of harmful volatile organic compound(i.e., toluene) and greenhouse gas(i.e., methane). The demonstrated direct involvement of metal atoms on oxide support suggests that the real active sites of atomically dispersed metal catalysts can be far beyond isolated metal atoms themselves. Metal atoms on oxide supports in the vicinity serve as another vector to promote the catalysis of atomically dispersed metal catalysts. | Pengxin Liu Yun Zhao Ruixuan Qin Lin Gu Peng Zhang Gang Fu Nanfeng Zheng | 2018 | Science Bulletin2018，63，11： | 13 |
| 5 | Preliminary evaluation of the long-term GLASS albedo product显示文摘Land surface albedo is an important parameter to describe the radiant forcing in the climate system.A long-time series of global albedo products is needed to understand the mechanism of climate change.Aiming to support global change and Earth system studies,GLASS(Global LAnd Surface Satellites)provides long-term global land surface albedo product from 1981 to 2010,which are generated from multisource remote sensing data and newly developed algorithms.It is critical to assess the quality of the GLASS product when it is released to the public.This paper first introduced the algorithms and then analyzed the integrity,accuracy,and robustness of the GLASS albedo product.The results show that the GLASS albedo product is a gapless,long-term continuous,and self-consistent data-set with an accuracy similar to that of the widely acknowledged MODIS MCD43 product.The quality flag,which is provided along with the black-sky and white-sky albedo,gives a pertinent indication of the expected uncertainty in the product. | Qiang Liua Lizhao Wang Ying Qu Nanfeng Liu Suhong Liu Hairong Tang Shunlin Liang | 2013 | International Journal of Digital Earth2013，6，S01： | 7 |
| 6 | Interfacial Activation of Catalytically Inert Au(6.7 nm)-Fe_(3)O_(4)Dumbbell Nanoparticles for CO Oxidation显示文摘Au nanoparticles epitaxially grown on Fe_(3)O_(4)in Au(6.7 nm)-Fe_(3)O_(4)dumbbell nanoparticles exhibit excellent stability against sintering,but display negligible catalytic activity in CO oxidation.Starting from various supported Au(6.7 nm)-Fe_(3)O_(4)catalysts prepared by the colloidal deposition method,we have unambiguously identifi ed the significance of the Au-TiO_(2)interface in CO oxidation,without any possible size effect of Au.In situ thermal decomposition of TiO_(2)precursors on Au-Fe_(3)O_(4)was found to be an effective way to increase the Au-TiO_(2)interface and thereby optimize the catalytic performance of TiO_(2)-supported Au-Fe_(3)O_(4)dumbbell nanoparticles.By reducing the size of Fe_(3)O_(4)from 15.2 to 4.9 nm,the Au-TiO_(2)contact was further increased so that the resulting TiO_(2)-supported Au(6.7 nm)-Fe_(3)O_(4)(4.9 nm)dumbbell particles become highly efficient catalysts for CO oxidation at room temperature. | Binghui Wu Hai Zhang Cheng Chen Shuichao Lin Nanfeng Zheng | 2009 | Nano Research2009，2，12： | 7 |

| 8 | Safety profile of two-dimensional Pd nanosheets for photothermal therapy and photoacoustic imaging显示文摘二维(2D ) nanosheets 在 biomedicines 的领域里与大潜力作为 nanomaterial 的一个重要的类出现了,特别地在癌症 theranostics。然而,由于综合的有效方法的缺乏有控制尺寸的一致 2D nanomaterials, 2D nanomaterials 的尺寸依赖者简历行为的系统的评估很少被报导。就我们的知识而言,我们是第一报导对他们的简历行为的 2D nanomaterials 的尺寸的影响的系统的评估。有从 5 ~ 80 nm 的直径的 2D Pd nanosheets 被综合并且在房间和动物模型测试了估计他们基因表示介绍的尺寸依赖者 bioapplication, biodistribution,消除,毒性,和 genomic。我们的结果证明尺寸显著地影响 Pd nanosheets 的生物行为,包括他们的 photothermal 和 photoacoustic 效果, pharmacokinetics,和毒性。比作大尺寸的 Pd nanosheets,更展出的小尺寸的 Pd nanosheets 在 ultralow 之上预付 photoacoustic 成像和 photothermal 效果激光照耀。而且,在 vivo,结果显示 5-nm Pd nanosheets 与更长的血半衰期逃离网状内皮组织的系统并且能被肾的排泄清除,当时有更大的尺寸的 Pd nanosheets 主要在肝和怒气积累。30-nm Pd nanosheets 展出了最高的肿瘤累积。尽管 Pd nanosheets 没在细胞的水平引起任何可估计的毒性,我们在怒气在肝和发炎观察了细微类脂化合物累积。Genomic 基因表达式分析证明 80-nm Pd nanosheets 与更细胞的部件交往了并且在肝影响了更生物的进程,作为与 5-nm Pd nanosheets 相比。我们相信这个工作将作为 nanomedicines 提供珍贵信息和卓见进 2D Pd nanosheets 的临床的申请。 | Mei Chen Shuzhen Chen Chengyong He Shiguang Mo Xiaoyong Wang Gang Liu Nanfeng Zheng | 2017 | Nano Research2017，10，4： | 5 |
| 9 | Preface: single-atom catalysts as a new generation of heterogeneous catalysts显示文摘Heterogeneous catalysis plays a leading role in the chemical industry. Creating heterogeneous catalysts with minimal use of metals but well-defined catalytic sites is highly desired for developing cost-effective and green chemical processes. With single metal atoms dispersed on supports, single-atom catalysts are featured in their optimized usage of metal and also the similar chemical environments of metal sites. It has been long believed that the single-atom catalysts should not be stable enough to be prepared via conventional catalyst-preparation techniques. | Nanfeng Zheng Tao Zhang | 2018 | National Science Review2018，5，5： | 4 |
| 10 | Two-dimensional Pd-based nanomaterials for bioapplications显示文摘Noble metal nanomaterials have been extensively explored in cancer diagnostic and therapeutic applications owing to their unique physical and chemical properties, such as facile synthesis, straightforward surface functionalization, strong photothermal effect, and excellent biocompatibility. Herein, we summarize the recent development of two-dimensional(2D) Pd-based nanomaterials and their applications in cancer diagnosis and therapy. Different synthetic strategies for Pd nanosheets and the related nanostructures, including Pd@Au, Pd@Ag nanoplates and mesocrystalline Pd nanocorolla, are first discussed.Together with their unique properties, the potential bioapplications of these 2D Pd nanomaterials are then demonstrated. With strong absorption in near-infrared(NIR) region, these nanomaterials have great potentials in cancer photothermal therapy(PTT). They also readily act as contrast agents in photoacoustic(PA) imaging or X-ray computed tomography(CT) to achieve image-guided cancer therapy. Moreover,significant efforts have been devoted to studying the combination of PTT and other treatment modalities(e.g., chemotherapy or photodynamic therapy) based on Pd nanomaterials. The remarkable synergistic or collaborative effects to achieve better therapeutic efficacy are discussed as well. Additionally, the biosafety of 2D Pd-based nanomaterials in vitro and in vivo was evaluated. Finally, challenges for the applications of Pd-based nanomaterials in cancer diagnosis and therapy, and future research prospects are highlighted. | Xiaolan Chen Saige Shi Jingping wei Mei Chen Nanfeng Zheng | 2017 | Science Bulletin2017，62，8： | 4 |
| 11 | Coordination chemistry of atomically dispersed catalysts显示文摘The last decade has witnessed the rapid development of atomically dispersed catalysts.With every active metal atom anchored on the surface of supports, atomically dispersed catalysts offer the maximum atom efficiency,helping to create cost-effective catalysts,particularly those based on earth-scarce metals. While it is still in intense debate whether single metal atoms can provide better catalytic activities than surface atoms of metal nanoparticles,an increasing number of studies have been revealing that the subtle chemical environment surrounding the catalytic metal atoms plays a critical role in determining the overall catalytic performance of an atomically dispersed catalyst. | Pengxin Liu Nanfeng Zheng | 2018 | National Science Review2018，5，5： | 3 |
| 12 | Effect of glutathione on in vivo biodistribution and clearance of surface-modified small Pd nanosheets显示文摘Plasmonic Pd nanosheets have been emerging as promising materials for application in near-infrared(NIR) photothermal therapy(PTT) of cancer. However, animal in mice studies indicated that the original synthesized poly(vinylpyrrolidone)(PVP)-protected small Pd nanosheets(Pd-PVP) and some further surface-modified small Pd nanosheets such as Pd-PEG(SH) easily accumulated in reticuloendothelial system(RES) organs(liver, spleen, etc.) and were difficult to be cleared from these organs quickly. In the work, we surprisingly found that glutathione(GSH) could promote the clearance of surface-modified small Pd nanosheets(e.g. Pd-PVP, Pd-PEG(SH) and Pd-GSH) from the RES organs efficiently. The effects of GSH on the biodistribution and clearance of different surface-modified Pd nanosheets were investigated. Our results indicated that these surface-modified Pd nanosheets with or without GSH added caused no morbidity at target primary organs, and GSH can promote the clearance of different surface-modified Pd nanosheets in the order of Pd-PVP≈Pd-PEG(SH)>Pd-GSH. This study suggests that glutathione could be an attractive reagent for promoting nanomaterials eliminated from the reticuloendothelial systems(RES). | Yizhuan Huang Xiaolan Chen Saige Shi Mei Chen Shaoheng Tang Shiguang Mo Jingping Wei Nanfeng Zheng | 2015 | Science China Chemistry2015，58，11： | 3 |
| 13 | Thiol-stabilized atomically precise, superatomic silver nanoparticles for catalysing cycloisomerization of alkynyl amines显示文摘Both the electronic and surface structures of metal nanomaterials play critical roles in determining their chemical properties. However, the non-molecular nature of conventional nanoparticles makes it extremely challenging to understand the molecular mechanism behind many of their unique electronic and surface properties. In this work, we report the synthesis, molecular and electronic structures of an atomically precise nanoparticle, [Ag206 L72]~q(L = thiolate, halide; q = charge). With a four-shell Ag7@Ag32@Ag77@Ag90 Ino-decahedral structure having a nearly perfect D_(5h) symmetry, the metal core of the nanoparticle is co-stabilized by 68 thiolate and 4 halide ligands. Both electrochemistry and plasmonic absorption reveal the metallic nature of the nanoparticles, which is explained by density functional theory calculations.Electronically, the nanoparticle can be considered as a superatom, just short of a major electron shell closing of 138 electrons(q = –4). More importantly, many of ligands capping on the nanoparticle are labile due to their low-coordination modes, leading to high surface reactivity for catalysing the synthesis of indoles from 2-ethynylaniline derivatives. The results exemplify the power of the atomic-precision nanocluster approach to catalysis in probing reaction mechanisms and in revealing the interplay of heterogeneous reactivities,electronic and surface structural dynamics, thereby providing ways for optimization. | Juanzhu Yan Jun Zhang Xumao Chen Sami Malola Bo Zhou Elli Selenius Xiaomin Zhang Peng Yuan Guocheng Deng Kunlong Liu Haifeng Su Boon K.Teo Hannu Hakkinen Lansun Zheng Nanfeng Zheng | 2018 | National Science Review2018，5，5： | 3 |
| 14 | Facile synthesis of size-tunable ZIF-8 nanocrystals using reverse micelles as nanoreactors显示文摘This paper describes a robust method for the synthesis of high-quality ZIF-8 nanocrystals using reverse micelles as discrete nanoscale reactors.The precise size control of ZIF-8 nanocrystals is conveniently achieved by tuning the concentration of precursors,reaction temperatures,the amount of water,and the structure of surfactants.The as-synthesized ZIF-8 nanocrystals are of narrow distribution and tunable size.A size-dependent catalytic activity for Knoevenagel condensation reaction is further demonstrated by using ZIF-8 nanocrystals with different sizes as the catalysts.This facile method opens up a new opportunity in the synthesis of various ZIFs nanocrystals. | ZHAO XiaoJing FANG XiaoLiang WU BingHui ZHENG LanSun ZHENG NanFeng | 2014 | Science China Chemistry2014，57，1： | 3 |
| 15 | Tumor-associated Exosomes Are Involved in Hepatocellular Carcinoma Tumorigenesis, Diagnosis, and Treatment显示文摘Hepatocellular carcinoma(HCC)has become a challenging disease worldwide.There are still limitations in the diagnosis and treatment of HCC,and its high metastatic capacity and high recurrence rate are the main reasons for its poor prognosis.The ability of extracellular vesicles(EVs)to transfer functionally-active substances and their widespread presence in almost all body fluids suggest their unprecedented potential in the study of various cancers.The unique physicochemical properties of EVs determine their potential as antitumor vaccines and drug carriers.In the last decade,the study of EVs in HCC has evolved from a single hot topic to a system with considerable scale.This paper summarizes the role of EVs,especially exosomes,in the occurrence,metastasis and tumor immunity of HCC,reviews their applications in tumor diagnosis,prognosis and treatment,describes the pros and cons of these studies,and looks forward towards the future research directions of EVs in HCC. | Hang Wang Liang Yu Peng Huang Yongxu Zhou Wangyang Zheng Nanfeng Meng Risheng He Yi Xu Tey Sze Keong Yunfu Cui | 2022 | Journal of Clinical and Translational Hepatology2022，10，3： | 2 |
| 16 | Molecular imaging of advanced atherosclerotic plaques with folate receptor-targeted 2D nanoprobes显示文摘Vulnerable atherosclerotic plaques are responsible for most cardiovascular diseases(CVDs).Folate receptor(FR)positive activated macrophages were thought to be a prominent component in the development of vulnerable plaque.The objective of this study is to develop folate conjugated two-dimensional(2D)Pd@Au nanomaterials(Pd@Au-PEG-FA)for targeted multimodal imaging of the FRs in advanced atherosclerotic plaques.Pharmacokinetic and imaging studies(single photon emission computed tomography(SPECT),computed tomography(CT)and photoacoustic(PA)imaging)were performed to confirm the prolonged blood half-life and enrichment of radioactivity in atherosclerotic plaques.Strong signals were detected in vivo with SPECT,CT and PA imaging in heavy atherosclerotic plaques,which were significantly higher than those of the normal aortas after injection of Pd@Au-PEG-FA.Blocking studies with preinjection of excess FA could effectively reduce the targeting ability of Pd@Au-PEG-FA in atherosclerotic plaques,further demonstrating the specific binding of Pd@Au-PEG-FA for plaque lesions.Histopathological characterization revealed that the signal of probe was in accordance with the high-risk plaques.In summary,the Pd@Au-PEG-FA has favorable pharmacokinetic properties and provides a valuable approach for detecting high-risk plaques in the presence of FRs in atherosclerotic plaques. | Zhide Guo Liu Yang Mei Chen Xuejun Wen Huanhuan Liu Jingchao Li Duo Xu Yuanyuan An Changrong Shi Jindian Li Xinhui Su Zijing Li Ting Liu Rongqiang Zhuang Nanfeng Zheng Haibo Zhu Xianzhong Zhang | 2020 | Nano Research2020，13，1： | 2 |
| 17 | Antioxidant high-conductivity copper paste for low-cost flexible printed electronics显示文摘The flexible printed electronics(e.g.,wearable devices,roll-up displays,heating circuits,radio frequency identification(RFID)tags)calls for high-conductivity and low-cost materials,particularly for copper pastes.It is still a big challenge to develop reliable copper pastes for both antioxidant and high-conductivity flexible printed films and lines.In this work,an antioxidant copper paste was achieved using copper microflakes with surface passivation by formate ions and thiols,with high conductivity of 13400 S cm^(−1)(the same order of magnitude of silver pastes,1.8-2.5×10^(4) S cm^(−1)).The universal applications of as-prepared copper paste in flexible printed electronics(e.g.,electromagnetic interference(EMI)shielding films,anti-fog films,and RFID tags)via screen printing and curing at 170℃ under ambient atmosphere were demonstrated.The as-printed electronics showed high performance in flexibility,stability,and reliability.This work shows the great potential of anti-oxidation copper pastes in low-cost flexible printed electronics for commercial usage. | Shuqing Hong Chimin Liu Shuqiang Hao Wenxing Fu Jian Peng Binghui Wu Nanfeng Zheng | 2022 | npj Flexible Electronics2022，6，1： | 1 |
