Nanoscale Horizons (IF: pending)



1. A metal–semiconductor nanocomposite as an efficient oxygen-independent photosensitizer for photodynamic tumor therapy

Nanoscale Horiz., 2017, Advance Article

DOI: 10.1039/C7NH00087A



Metal deposition on semiconductors is a well-known method to improve catalytic efficiency, but it has rarely been applied to biomedical applications. Here, researchers from Wuhan University use this concept to generate reactive oxygen species for photodynamic therapy in an oxygen-independent way.


在半导体上沉积金属是一种众所周知的提高催化效率的方法,但很少应用于生物医学领域。在本文中,武汉大学的研究人员基于这一概念制得了用于光动力学治疗的光敏剂,在不依赖氧气的情况下生成活性氧物种。

2. Metal–organic framework derived hollow CoS2 nanotube arrays: an efficient bifunctional electrocatalyst for overall water splitting

Nanoscale Horiz., 2017, Advance Article

DOI: 10.1039/C7NH00079K


Metal–organic frameworks (MOFs) and their derivatives have received considerable attention in electrocatalysis. However, most of the previous studies focused on particle-like structures, and the electrode materials were prepared in powdered forms. Here, researchers from National University of Singapore present a novel hollow CoS2 nanotube array that has been rationally designed on a flexible carbon cloth substrate from a MOF precursor. The resulting structure can be directly used as a flexible catalyst for both the oxygen evolution reaction and the hydrogen evolution reaction with high electrochemical performance.


金属有机框架(MOFs)及其衍生物在电催化领域备受关注。然而,以往的多数研究集中于颗粒状结构,且电极材料以粉末形式制备。在本文中,新加坡国立大学的研究人员提出了一种设计合理的新型空心CoS2纳米管阵列,这种结构来自MOF前驱体,并以柔性碳布为基底。所得到的结构可直接用作析氧反应和析氢反应的柔性催化剂,并且具有优异的电化学性能。

3. Kinetic enhancement in high-activity enzyme complexes attached to nanoparticles

Nanoscale Horiz., 2017, 2, 241-252

DOI: 10.1039/C7NH00052A



Researchers from U.S. Naval Research Laboratory - NRL and George Mason University provide insight into the growing phenomena of enzyme enhancement when displayed at a nanoparticle interface. They develop, for the first time, a de novo model to describe the activity of an enzyme. Beyond just the enzyme, this model accounts for many of the interactions between the substrate, product, and nanoparticle. It is shown to be able to predict activities that agree well with experimental tests.


美国海军研究实验室(NRL)和乔治梅森大学的研究人员对纳米颗粒表面酶活性增强这种越来越普遍的现象进行了深入探究。他们首次开发了用以描述酶活性的从头计算模型。除了酶之外,这种模型还适用于底物、产物与纳米颗粒之间的多种相互作用。该模型活性预测的结果与实验测试高度吻合。

Chemical Science (IF: 8.668)



1. Chiral nanoprobes for targeting and long-term imaging of the Golgi apparatus

Chem. Sci., 2017, Advance Article

DOI: 10.1039/C7SC01316G


Chinese researchers have developed a method for long-term imaging of the Golgi apparatus. Chiral carbon quantum dots with abundant L-cysteine residues were prepared that exhibited high Golgi specificity, due to the L-type stereo structure, and excellent photostability and biocompatibility. The chiral dots were able to visualise changes in the Golgi in the early stages of viral infection. This strategy has the potential for Golgi-targeted drug delivery and early diagnosis and therapy of Golgi diseases.


西南大学与北京大学的研究人员发展了一种高尔基体长期成像的方法。他们制备了一种大量L-半胱氨酸残基修饰的手性碳量子点,得益于其L-型立体结构,这些量子点对高尔基体表现出高度的特异性,并具有优异的光稳定性和生物相容性。在病毒感染的早期阶段,这些手性量子点就能够使得高尔基体的变化可视化。这种策略有望用于高尔基体的靶向给药以及高尔基体相关疾病的早期诊断和治疗。

2. Selective cobalt nanoparticles for catalytic transfer hydrogenation of N-heteroarenes

Chem. Sci., 2017, Advance Article

DOI: 10.1039/C7SC02062G


Collaborators in Germany and China report nitrogen modified heterogeneous cobalt catalysts supported on carbon, prepared using melamine as the nitrogen source. The nanostructured materials catalyse the transfer hydrogenation of N-heteroarenes with formic acid and, unlike most known transfer hydrogenations, no addition of base was necessary. A broader substrate scope and improved functional group tolerance were also realized with the novel material.


德国罗斯托克大学莱布尼茨催化研究所与中国科学院兰州化学物理研究所苏州研究院的研究人员合作报道了含氮化合物修饰的多相碳负载钴催化剂,以三聚氰胺为氮源制备而得。这种纳米结构材料可催化N-杂芳烃与甲酸的转移氢化反应。与大多数已知的转移氢化反应不同,反应无需加入碱。这种新型催化剂具有更广阔的底物适用范围和更好的官能团兼容性。
