Construction of High-performance Biosensor Interface through Solvent Controlled Self-assembly of PEG grafted Polymer

Zhou C., keersmaecker K.De, Braeken D., Reekmans G., Bartic C., De Smedt H., Engelborghs Y., Borghs G., Interuniversity Microelectronics Center (IMEC), BE

The ability to control biomolecular interactions at the solid-liquid interface is essential for the development of high-performance biosensors. Conventional methods to tailor the surface properties of biosensors are based on Self-Assembled Monolayers (SAMs) and Surface [...]

Self-Assembled Soft Nanomaterials from Renewable Resources

John G., City College of the City University of New York, US

The self-assembly of low molecular weight building blocks into nanoscale molecular objects has recently attracted considerable interest in terms of the bottom-up fabrication of nanomaterials. The building blocks currently used in supramolecular chemistry are synthesized [...]

Electrohydrodynamic Patterning of Thin Polymer Film

Wu N., Pease III L.F., Russel W.B., Princeton University, US

A polymer melt sandwiched with a gap fluid between two planner electrodes can self assemble into ordered microstructures under the influence of an electric field. Motivated by the variety of patterns observed in experiments, we [...]

Characterisation of Drug Nanoparticles by Atomic Force Microscopy

Bailey N.A., Booth J., Clark B.C., AstraZeneca, UK

A key consideration when developing a drug nanoparticle formulation, particularly when intended for parenteral administration, is the control of particle size, shape and physical properties such as dissolution rate and stability with respect to Ostwald [...]

Thermodynamic Characterization of Nanoscale Materials

Smith A.L., Masscal Corporation, US

“The largest barrier to rational design and controlled synthesis of nanomaterials with predefined properties is the lack of fundamental understanding of thermodynamic and kinetic processes at the nanoscale. …Bulk material properties are not size-dependent, but [...]

Transmission Spectrum of PDMS in 4-7µm Mid-IR Range for Characterization of Protein Structure

Chen K-C, Chen Y.F., Wo A.M., Chen K-C, Chen Y.F., National Taiwan University, TW

Infrared (IR) spectroscopy has been an important tool to characterize secondary structure of proteins for decades. To extend PDMS-based micro-device into spectroscopic characterization of proteins for structural study, the transmission spectrum of PDMS over the [...]

Analysis of Surface Interaction between TiO2 Fine Particles with Different Surface Modification in Isoparaffin by Using Colloid Probe AFM

Kamiya H., Suzuki M., Kikuchi M., Iijima M., Tsukada M., Tokyo University of Agriculture and Technology, JP

To control the dispersion stability of nanometer scaled fine inorganic particles in organic solvent, various kinds of surface modification on particles have been carried out. This paper focused on the surface modification on titanium oxide [...]

Multiscale Modeling of Polymer Based Nanomaterials

Smith G.D., Smith J.S., Bedrov D., Borodin O., Smith G.D., Smith J.S., University of Utah, US

In materials design and engineering there is a need for fundamental information that spans large scales of time and distances, from the quantum chemical nature of interactions to the macroscopic mechanical, and electrical properties. In [...]

Lattice Boltzmann simulation of emulsification in microfluidics devices

van der Graaf S., van der Sman R.G.M., van der Graaf S., van der Sman R.G.M., Wageningen University, NL

Using microdevices we investigate the manufacturing of surfactant stabilised monodisperse food emulsions. Design of the process is a complicated matter, involving knowledge of wetting behaviour, droplet breakup in confined systems, surfactant dynamics coupled to droplet [...]

Interaction between polyether- poly (2-dimethylaminoethyl methacrylate)copolymers and phospholipid model vesicles – implications for gene delivery efficiency

Tan J.F., Bromberg L., Tam K.C., Too H.P., Hatton T.A., Singapore-MIT Alliance, SG

Our previous studies have demonstrated that surface-active copolymers of Pluronic® surfactants and tertiary amino polycations such as poly (2-dimethylaminoethyl methacrylate) (pDMA) possess an enhanced DNA transfection efficiency compared to pDMA homopolymers. The transfection efficiencies of [...]
