Morphological Diversity and Polymorphism of Self-Assembling Collagen Peptides Controlled by Length of Hydrophobic Domains

17-Nov-2014 | Kenneth McGuinness; I. John Khan; Vikas Nanda, ACS Nano, 2014

Synthetic collagen mimetic peptides are used to probe the role of hydrophobic forces in mediating protein self-assembly. Higher order association is an integral property of natural collagens, which assemble into fibers and meshes that comprise the extracellular matrix of connective tissues. The ...

Gas–liquid dielectric barrier discharge falling film reactor for the decoloration of dyeing water

14-Nov-2014 | Xuelan Feng, Binhang Yan, Qianli Yang, Yong Jin, Yi Cheng, Journal of Chemical Technology & Biotechnology, 2014

Abstract Background Decoloration of dyes is a top priority to enhance the biodegradability in the color‐free wastewater post‐treatment. A gas–liquid dielectric barrier discharge (DBD) falling film reactor is developed as a promising approach for the decoloration of ...

Cy3 and Cy5 Dyes Terminally Attached to 5′C End of DNA: Structure, Dynamics, and Energetics

14-Nov-2014 | Ondřej Kroutil; Ingrid Romancová; Miroslav Šíp; Zdeněk Chval, Journal of Physical Chemistry B, 2014

Cy3 and Cy5 cyanine dyes terminally attached to the 5′C end (C1) of the DNA oligonucleotide were studied by metadynamics (MTD), molecular dynamics (MD), and density-functional methods with dispersion corrections (DFT-D). MTD simulations explored the free energy surface (FES) of the dye–DNA ...

Materials, Vol. 7, Pages 7349-7365: Photo-Electrochemical Treatment of Reactive Dyes in Wastewater and Reuse of the Effluent: Method Optimization

14-Nov-2014 | Sala, Mireia ; López-Grimau, Víctor ; Gutiérrez-Bouzán, Carmen, Materials, 2014

In this work, the efficiency of a photo-electrochemical method to remove color in textile dyeing effluents is discussed. The decolorization of a synthetic effluent containing a bi-functional reactive dye was carried out by applying an electrochemical treatment at different intensities (2 A, 5 A ...

Potentiometric Response from Ion-Selective Nanospheres with Voltage-Sensitive Dyes

14-Nov-2014 | Xiaojiang Xie; Jingying Zhai; Eric Bakker, Journal of the American Chemical Society, 2014

Potentiometric sensors require the implementation of conducting wires for signal transduction, but this is impractical for the readout of individual nanoparticles. It is here demonstrated for the first time that the potentiometric response of ion-selective nanospheres can be observed with ...

ChemInform Abstract: Evolution of BODIPY Dyes as Potential Sensitizers for Dye‐Sensitized Solar Cells

13-Nov-2014 | Surya Prakash Singh, Thumuganti Gayathri, ChemInform, 2014

Abstract Review: [51 refs.

Anomalous Diffusion in Thermoresponsive Polymer–Clay Composite Hydrogels Probed by Wide-Field Fluorescence Microscopy

13-Nov-2014 | Beate Stempfle; Anna Große; Bernhard Ferse; Karl-Friedrich Arndt; Dominik Wöll, Langmuir, 2014

Thermoresponsive materials exhibit an enormous potential for tissue engineering, separation systems, and drug delivery. We investigated the diffusion of laponite clay nanoparticles, which serve as physical cross-linkers to achieve improved material properties in poly(N-isopropylacrylamide) ...

Complementary Surface Second Harmonic Generation and Molecular Dynamics Investigation of the Orientation of Organic Dyes at a Liquid/Liquid Interface

13-Nov-2014 | Denis Svechkarev; Dmitry Kolodezny; Sandra Mosquera-Vázquez; Eric Vauthey, Langmuir, 2014

The second-order nonlinear response of two dyes adsorbed at the dodecane/water interface was investigated by surface second harmonic generation (SSHG). These dyes consist of the same chromophoric unit, 2-pyridinyl-5-phenyloxazole, with an alkyl chain located at the two opposite ends. The analysis ...

Multiplexed Modular Genetic Targeting of Quantum Dots

12-Nov-2014 | Saumya Saurabh; Lauren E. Beck; Suvrajit Maji; Catherine J. Baty; Yi Wang; Qi Yan; Simon C. Watkins; Marcel P. Bruchez, ACS Nano, 2014

While DNA-directed nanotechnology is now a well-established platform for bioinspired nanoscale assembly in vitro, the direct targeting of various nanomaterials in living biological systems remains a significant challenge. Hybrid biological systems with integrated and targeted nanomaterials may ...

A DNA-Directed Light-Harvesting/Reaction Center System

12-Nov-2014 | Palash K. Dutta; Symon Levenberg; Andrey Loskutov; Daniel Jun; Rafael Saer; J. Thomas Beatty; Su Lin; Yan Liu; Neal ..., Journal of the American Chemical Society, 2014

A structurally and compositionally well-defined and spectrally tunable artificial light-harvesting system has been constructed in which multiple organic dyes attached to a three-arm-DNA nanostructure serve as an antenna conjugated to a photosynthetic reaction center isolated from Rhodobacter ...
