      Inhibition of Aβ aggregation has shown promising against Alzheimer's disease in clinical trials. X. Qu and co-workers report a novel strategy on page 1722 which can dissociate amyloid aggregation using local heat generated by a clinically used amyloid-staining, dye-modified graphene oxide (GO) under NIR laser irradiation. With its high NIR absorbance, good biocompatibility, and its ability to cross the blood-brain barrier, the newly synthesized GO can efficiently dissociate Aβ fibrils, protect cells against Aβ-related toxicity, and be monitored in real time.

In this image, the controllable doping of orange/green acceptors in the blue-emitting matrix is compared to optional painting with a brush in different colors. The fluorescence image in the background shows the well-defined morphology and high monodispersity of the samples. These light-emitting heterostructures are applicable for integrated microscale optoelectronics as functional wavelength converters.

      Highly sensitive, multicomponent broadband photodetector devices are made from PbSe/graphene/TiO2. TiO2 and PbSe nanoparticles act as light harvesting photoactive materials from the UV to IR regions of the electromagnetic spectrum, while the graphene acts as a charge collector for both photogenerated holes and electrons under an applied electric field.

    3. One-Dimensional Organic Photonic Heterostructures: Rational Construction and Spatial Engineering of Excitonic Emission (pages 1703–1708)

      Chuang Zhang, Yongli Yan, Yuan-Yuan Jing, Qiang Shi, Yong Sheng Zhao and Jiannian Yao

      Article first published online: 6 FEB 2012 | DOI: 10.1002/adma.201104326

      Thumbnail image of graphical abstract

      Organic photonic heterostructures are constructed through a template-free self-assembly method. The host-guest intermolecular interactions play an essential role in the formation of various block orange-blue-orange and blue/green microtubes. The spatial distribution of excitons is engineered to investigate the excitonic behaviors in light propagation along the axial heterostructures. These results offer a new route to the integration of organic photonic building blocks for optical processing applications.

      Thumbnail image of graphical abstract

      A novel strategy to dissociate amyloid aggregation is presented, using localised heat generation from a clinically used amyloid staining dye, thioflavin-S (ThS)-modified graphene oxide (GO) under NIR laser irradiation. Compared to traditional chemotherapies, photothermal therapy shows reduced side effects and improved selectivity and safety.

    7. Piezo-Phototronic Effect-Induced Dual-Mode Light and Ultrasound Emissions from ZnS:Mn/PMN–PT Thin-Film Structures (pages 1729–1735)

      Yang Zhang, Guanyin Gao, Helen L.W. Chan, Jiyan Dai, Yu Wang and Jianhua Hao

      Article first published online: 6 MAR 2012 | DOI: 10.1002/adma.201104584

      Thumbnail image of graphical abstract

      Electric-field-controllable luminescence of a ZnS:Mn/PMN–PT system is demonstrated. The light-emission of ZnS:Mn is caused by the piezoelectric potential, resulting from the converse piezoelectric effect of the PMN–PT substrate. Simultaneous generation of light and ultrasound waves is observed in this single system, which offers great potential to develop a dual-modal source combing light and ultrasonic waves for various applications.

      Inclusion bodies (50–500 nm in diameter) produced in recombinant bacteria can be engineered to contain functional proteins with therapeutic potential. Upon exposure, these protein particles are efficiently internalized by mammalian cells and promote recovery from diverse stresses. Being fully biocompatible, inclusion bodies are a novel platform, as tailored nanopills, for sustained drug release in advanced cell therapies.

    2. Quantum-Dot-Tagged Reduced Graphene Oxide Nanocomposites for Bright Fluorescence Bioimaging and Photothermal Therapy Monitored In Situ (pages 1748–1754)

      Shang-Hsiu Hu, Yu-Wei Chen, Wen-Ting Hung, I-Wei Chen and San-Yuan Chen

      Article first published online: 16 MAR 2012 | DOI: 10.1002/adma.201104070

      Thumbnail image of graphical abstract

      Quantum-dot-tagged reduced graphene oxide (QD-rGO) nanocomposites (left) internalized into targeted tumor cells display bright fluorescence from the QDs (right); by absorbing NIR radiation incident on the rGO and converting it into heat, they also cause simultaneous cell death and fluorescence reduction (bottom). The nanocomposite is thus capable of tumor imaging, photothermal therapy and in situ monitoring of treatment in progress.

      Article first published online: 5 MAR 2012 | DOI: 10.1002/adma.201200006

      Thumbnail image of graphical abstract

      A novel sandwich-type tris(phthalocyaninato) europium triple-decker complex bearing peripheral electron-withdrawing groups (see center of figure) is used to fabricate a field-effect transistor by the quasi-Langmuir–Schaefer method. The air-stable, single-component ambipolar OFET device displays the best carrier properties of a device fabricated by solution processing of a single phthalocyanine derivative so far, which makes the complex very promising for applications in nanoelectronics.

    5. Optimizing the Charge Balance of Fluorescent Organic Light-Emitting Devices to Achieve High External Quantum Efficiency Beyond the Conventional Upper Limit (pages 1765–1770)

      Yong-Jin Pu, Go Nakata, Fumiya Satoh, Hisahiro Sasabe, Daisuke Yokoyama and Junji Kido

      Article first published online: 7 MAR 2012 | DOI: 10.1002/adma.201104403

      Thumbnail image of graphical abstract

      The external quantum efficiencies (EQEs) of fluorescent light emitting devices are drastically improved by optimizing the charge balance. When N,N′-di(naphthalene-1-yl)- N,N′-diphenylbenzidine (NPD) is used as a hole-transporting layer (HTL) and Alq3 as an electron-transporting layer (ETL) with the green dopant 2,3,6,7-tetrahydro-1,1,7,7-tetramethyl-1H,5H,11H-10-(2-benzothiazolyl)quinolizino-[9,9a,1gh]coumarin (C545T), the EQE is observed to be approximately 3%. However, when the HTL and ETL materials are optimized, a 7.5% external quantum efficiency (EQE) in a green-emitting device and an 8.2% EQE in a blue-emitting device are achieved at 100 cd m−2.
