Transistors: Charge Transfer and Current Fluctuations in Single Layer Graphene Transistors Modified by Self-Assembled C60Adlayers (Small 14/2013)

Rui Wang,Shengnan Wang,Xiaowei Wang,Jakob A. S. Meyer,Per Hedegård,Bo W. Laursen,Zhihai Cheng,Xiaohui Qiu

The flicker noise in a ‘fullerene + graphene’ hybrid transistor is measured by X. H. Qiu and co-workers on page 2420 to reveal the electrical coupling between its graphene channel and C60adsorbates. The charge associated with the trapping and detrapping processes at the C60/graphene interface induces current fluctuations in the device. The temperature-dependent noise characteristics indicate that the two contributions are related to Coulomb scattering and charge-exchange kinetics. This represents a practical template for developing graphene-based biosensors and nanoelectrodes.

Carbon Nanotubes: Short Multiwall Carbon Nanotubes Promote Neuronal Differentiation of PC12 Cells via Up-Regulation of the Neurotrophin Signaling Pathway (Small 9–10/2013)

Li Meng,Rui Chen,Aihua Jiang,Liming Wang,Peng Wang,Chen-zhong Li,Ru Bai,Yuliang Zhao,Herman Autrup,Chunying Chen

The front cover image for this special issue was provided by C. Chen and co-workers. CNTs show good biocompatibility, and can be used to modulate neurite outgrowth in culture and in vivo. Positive effects such as promoting regeneration and differentiation can be initiated by up-regulating cellular uptake and exocytosis. On page 1786 it is shown that shorter carboxyl-terminated multiwall carbon nanotubes (MWCNTs) demonstrate higher cellular uptake by PC12 cells and more obvious exocytosis compared to longer ones. Incubation of PC12 cells with carboxylated MWCNTs does not affect cellular morphology or viability at lower concentrations.

Photoswitches: High Performance Photoswitches Based on Flexible and Amorphous D–A Polymer Nanowires (Small 2/2013)

Yao Liu,Haifeng Wang,Huanli Dong,Lang Jiang,Wenping Hu,Xiaowei Zhan

Polymer nanowire photoswitches are integrated with flexible micro-optoelectronic panels by W. Hu, X. Zhan, and co-workers. On page 294, donor–acceptor polymer (PFTBT) nanowires are prepared on a large scale using a simple template-dipping method. The PFTBT individual nanowire photoswitches exhibit a photoresponsivity of 1700 mA W−1 and a photoswitch ratio of 2000 under a light intensity of 5.76 mW cm−2 and a driving voltage of 40 V. Even at low driving voltages of 2 V or with the nanowires bent at nearly 90 degrees, these devices exhibit highly reproducible on/off cycles with photoswitch ratios of over 200. Image designed by Y. Liu and X. Zhan, created using My SCImage.

Proteins: Biosafety and Bioapplication of Nanomaterials by Designing Protein–Nanoparticle Interactions (Small 9–10/2013)

Sheng-Tao Yang,Ying Liu,Yan-Wen Wang,Aoneng Cao

When nanomaterials (NMs) enter biosystems, they interact with various biomolecules, especially proteins, forming a protein corona on the surface. Understanding how nanoparticles (NPs) interact with proteins is crucial for bioapplications and for the biosafety of NMs. On page 1635, A. Cao and co-workers summarize the current understanding of protein–NP interactions. Guidelines for improving bioapplication performance and reducing the potential biosafety hazard of NMs by designing the protein–NP interactions are discussed, along with future directions and challenges in this exciting field.

Biomedical Applications: Imaging-Guided pH-Sensitive Photodynamic Therapy Using Charge Reversible Upconversion Nanoparticles under Near-Infrared Light (Adv. Funct. Mater. 24/2013)

Chao Wang,Liang Cheng,Yumeng Liu,Xiaojing Wang,Xinxing Ma,Zhaoyi Deng,Yonggang Li,Zhuang Liu

Smart charge-reversible upconversion nanoparticles are reported on page 3077 by Zhuang Liu and co-workers for pH-responsive, in vivo, near-infrared light excited photodynamic therapy. While stable under normal physiological pH, highly sensitive acid-induced charge conversion of the nanoparticles is observed in a slightly acidic tumor microenvironment, resulting in significantly enhanced cellular internalization of nanoparticles and remarkably improved photodynamic cancer cell killing in vitro and in vivo.

Biomedical Applications: Single Continuous Wave Laser Induced Photodynamic/Plasmonic Photothermal Therapy Using Photosensitizer-Functionalized Gold Nanostars (Adv. Mater. 22/2013)

Shouju Wang,Peng Huang,Liming Nie,Ruijun Xing,Dingbin Liu,Zhe Wang,Jing Lin,Shouhui Chen,Gang Niu,Guangming Lu,Xiaoyuan Chen

Chlorin e6-conjugated gold nanostars (GNSPEG-Ce6) are constructed by X. Chen, G. Lu, and co-workers on page 3055 as a novel theranostic system for imaging, and photodynamic and photothermal therapy. Utilizing the difference in photostability between chlorin e6 and gold nanostars, GNS-PEG-Ce6 can coordinate the early-phase photodynamic effect with the late-phase photothermal effect upon single wavelength continuous wave laser irradiation. With significantly improved anti-cancer efficacy and simplified treatment process, the GNS-PEGCe6 formula shows high potential for translation into clinical practice to treat cancer patients.

Nanowires: Bandgap-Graded CdSxSe1–x Nanowires for High-Performance Field-Effect Transistors and Solar Cells (Adv. Mater. 8/2013)

Liang Li,Hao Lu,Zongyin Yang,Limin Tong,Yoshio Bando,Dmitri Golberg

Bandgap-graded CdSxSe1−xnanowires are utilized by Liang Li and co-workers on page 1109 for high-performance field-effect transistors and Schottky solar cells. The photovoltaic mechanism is ascribed to the Schottky junction effect and the “type II” band structure which maximizes the driving force for the injection of photoexcited electrons into the CdS through CdSxSe1-x from the CdSe by creating an optimized band alignment.
