Self-assemblies of magnetic nanoparticles (MNPs) and peroxidase enzymes: mesoporous structures and nanoscale magnetic field effects (nano-MFEs) for enhanced activity BioNanoCatalysts (BNCs).

Corgié S.C., Duan X., Kahawong P., Edwards J., Walker L.P., Giannelis E.P., Cornell University, US

BNCs are self-assembled complexes of magnetic nanoparticles and free-radical producing enzymes, including peroxidases and other oxido-reductases that were shown to have higher activities than their free-enzyme counterparts (up to 30 folds). The BNCs biochemical properties [...]

Study on the novel drug vehicle with multimodal imaging function

Wu P.J., Liu T.Y., Institute of Biomedical Engineering, National Yang-Ming University of Taiwan (ROC), TW

Recently, in order to combine diagnosis with therapy in a single box, drug delivery systems (DDSs) associating with imaging functions were developed to improve the efficacy of diseases detection, delivery of therapeutic agents, and the [...]

Unravelling adsorption and alignment of amyloid fibrils at interfaces by probe particle tracking

Isa L., Jung J-M, Mezzenga R., Jordens S, ETH Zürich, CH

We report the first direct, non-invasive experimental evidence of a 2D isotropic–nematic transition for highly anisotropic nanoparticles at liquid–liquid interfaces by using passive fluorescent particle tracking. In order to illustrate the potential of this approach [...]

Fabrication of controlled linear assemblies of graphite nanosheets in polysiloxane-based nanocomposite films and enhancement of thermal property

Cho H.-B., Yanahara S., Nakayama T., Suematsu H., Suzuki T., Jiang W., Tanaka S., Niihara K., Nagaoka University of Technology, JP

In the present research, we report successful control of orientation and relocation of GNs in polymer matrix using electric and magnetic fields inducing external torques. According to modulation of the external torque, GNs can establish [...]

Design and Fabrication of a Large Scale Electric Field Array Device for Directed Self-Assembly of Multilayer BioDerivatized Nanoparticle Materials

Heller M.J., Song Y., University of California San Diego, US

In earlier work, an electronic microarray device was used to carry out a bottom-up approach for the directed self-assembly of higher order 3D structures from biotin/streptavidin, DNA and enzyme derivatized nanoparticles. Structures with up to [...]

Spectrally-Selective Light-Induced Release from Gold-Coated Liposomes

Leung S.J., Romanowski M., University of Arizona, US

To address unmet medical needs in the area of controlled delivery, we recently presented liposome-supported plasmon resonant gold nanoshells. These composite structures are degradable into components of a size compatible with renal clearance, potentially enabling [...]

A Helical Peptide can Mediate Electron over 120 Å by Hopping Mechanism

Arikuma Y., Nakayama H., Morita T., Kimura S., Kyoto University, JP

We have studied long-range electron transfer through various lengths of helical peptides from 8 mer (24 Å) up to 80 mer (120 Å) in self-assembled monolayers prepared on a gold surface. Helical peptides carrying a [...]

The Self-Assembly of Nano-Objects code (SANO-Grid) using Grid Interpolation technique: Application to epitaxial organic monolayers adsorbed on metal surfaces

Roussel T.J., Vega L.F., Consejo Superior de Investigaciones Científicas. (ICMAB-CSIC), ES

One of the main challenges is to precisely position the first molecular building blocks in the first layer of thin films in order to tune their hetero-epitaxial properties, or else to adjust the substrates for [...]

Investigation of Lead-free Nanosolder Reflow and Wettability Property for Electronics/Nanoelectronics Assembly and Packaging

Gao F., Gu Z., Shina S., Morose G., Eliason P., Farrell R., University of Massachusetts-Lowell, US

The current demand for high-performance interconnects in advanced packaging is resulting in dramatic scaling down of the electronics packaging feature size from microscale to nanoscale. Novel and/or enhanced interconnection and packaging techniques have to be [...]
