Based on soft-touch atomic force microscopy, a method is described to reconstruct the secondary structure of single extended biomolecules, without the need for crystallization. The method is tested by accurately reproducing the dimensions of the B-DNA crystal structure. Importantly, intramolecular variations in groove depth of the DNA double helix are resolved, which would be inaccessible for methods that rely on ensemble-averaging.

Next-generation polymeric scaffolds require biofunctionalization for tissue remodeling. Cryomilling, a solvent-free approach based on solid phase diffusion, is employed to achieve high percentage, and homogeneous distribution of tricalcium phosphate (TCP) in a polycaprolactone matrix. The process reduces size disparity between the two phases at liquid nitrogen temperature, enabling successful composite scaffold fabrication of up to 70 wt% TCP with uniform osteogenic activity.
- Monoclinic Porous BiVO4 Networks Decorated by Discrete g-C3N4 Nano-Islands with Tunable Coverage for Highly Efficient Photocatalysis

An efficient g-C3N4/BiVO4 heterojunction photocatalyst is constructed with BiVO4 networks decorated by discrete g-C3N4 nano-islands with controllable coverage. The as-synthesized g-C3N4/BiVO4 photocatalyst shows superior visible light photocatalytic activity. The enhanced photocatalytic activity can be ascribed to increased charge separation efficiency, separated redox reaction sites, fully exposed reactive interfaces and excellent visible light response of g-C3N4/BiVO4 composite.
- Magnetic Nanoparticles to Recover Cellular Organelles and Study the Time Resolved Nanoparticle-Cell Interactome throughout Uptake
Filippo Bertoli, Gemma-Louise Davies, Marco P. Monopoli, Micheal Moloney, Yurii K. Gun'ko, Anna Salvati and Kenneth A. Dawson
Article first published online: 16 APR 2014 | DOI: 10.1002/smll.201303841
The magnetic properties of silica coated magnetite nanoparticles are used to recover at different times the internalized nanoparticles from cells. This allows to characterize in a time resolved way the organelles in which nanoparticles are trafficked and the intracellular evolution of the layer of molecules adsorbed on the nanoparticle surface.

Jake Fontana, Walter J. Dressick, Jamie Phelps, John E. Johnson, Ronald W. Rendell, Travian Sampson, Banahalli R. Ratna and Carissa M. Soto

Plasmonic nanoclusters are fabricated by a self-assembly technique. Gold nanoparticles bind to an icosahedral genetically engineered plant virus. Purified samples result in a purple aqueous solution, which spectral characteristics agrees well with 3D finite-element simulations. Transmission electron micrographs confirms the assembly of nanoclusters with well-defined interparticle spacing and icoshahedral symmetry. This mehod has the potential for high-throughput providing a strategy to realize macroscopic quantities for metamaterial applications.
