DNA-DNA Interaction on Dendron-Functionalized Sol-Gel Silica Films Followed with Surface Plasmon Fluorescence Spectroscopy

Kwon S.H., Hong B.J., Park H.Y., Park J.W., Knoll W., Park H.Y., Park J.W., Center for Integrated Molecular System., KR

Since we observed that dendron-assembled surface providing a proper spacing between immobilized DNAs showed high single nucleotide polymorphism discrimination efficiency for DNA microarrays(1), the nanoscale-controlled surface is examined with surface plasmon field-enhanced fluorescence spectroscopy (or [...]

Nanoprobe for Optical Molecular Imaging

Zheng S., Wang R., Che W., Harrison W.J., Yang Z., Li C., Eastman Kodak Company, US

Optical molecular imaging (OMI) is a very powerful tool for studying the temporal and spatial dynamics of specific biomolecules and their interactions in real time in vivo. It exhibits the great advantages of high temporal [...]

Controlled Surfaces and Novel Polymers for Personal Care: Self-Assembly of Polymers and Surface Modification

Mowers W.A., Berg M.C., Suddaby N., Bercovici D., Soane D., Soane Labs / Cosmetica, US

Cosmetica develops and applies nanotechnology and advanced polymer chemistry to create novel products for the cosmetic industry. We achieve this goal by controlling the spontaneous self-assembly of polymers or colorants at surfaces. Current research projects [...]

Novel Supramolecules Based on Architecturally Variant alpha-Cyclodextrin Polyrotaxanes and Nanorod-Like alpha-Cyclodextrin Self-Assembly

Chung J.W., Yu B.-Y., Kwak S-Y, Seoul National University, KR

Self-assembly (SA-ICs) of architecturally variant alpha-cyclodextrin (alpha-CD) inclusion complexes (ICs) formed by host-guest reaction with four polymeric guest having different molecular architectures (star-shaped, hyperbranched, diblocked, and linear polymer) and nanorod-like self-assembly (SA-CD) of alpha-CD could [...]

Controlling the Surfaces of Food: Self-Assembly of Biopolymers

Berg M.C., Mowers W.A., Silberstein S.R., Soane D., DuraFizz, LLC, US

DuraFizz develops and applies nanotechnology-inspired innovations to the food industry by controlling the spontaneous self-assembly of biopolymers at surfaces. This principle is demonstrated in several current research projects including nutrient encapsulation, edible foams, and fryer [...]

Bio-inspired Polymers for Nanoscience Research

Lee B.C., Zuckermann R.N., The Molecular Foundry, Lawrence Berkeley National Laboratory, US

Peptoids are a novel class of non-natural biopolymer based on an N-substituted glycine backbone that are ideally suited for nanomaterials research. This bioinspired material has many unique properties that bridge the gap between proteins and [...]

Structural and rheological investigation of Fd3m inverse micellar cubic phases

Pouzot M., Mezzenga R., Leser M., Sagalowicz L., Nestlé Research Center, CH

Liquid crystalline phases (bicontinuous cubic, reversed hexagonal, lamellar) can be made easily from food emulsifiers such as monoglycerides. Recently we explored in detail the formation of an inverse discrete micellar Fd3m cubic phase, which usually [...]

Self-assembly of Carbon Nanotubes on Large Structures and on Ceramics

Karwa M., Brukh R., Saridara C., Wang Y., Iqbal Z., Mitra S., New Jersey Inst. of Technology, US

Self-assembly techniques as related to carbon nanotubes (CNTs) is explored. The first is the self-assembly on the inside wall of stainless steel tubings using C2H4 as the carbon source and the iron nanostructures in the [...]

Feasibility Study of Directed Self-Assembly of Semiconductor Quantum Dots

Friedman L.H., Xu J., Pennsylvania State University, US

Strain mismatched semiconductors are used to form Self-Assembled Quantum Dots (SAQDs). An important step in developing SAQD technology is to control randomness and disorder in SAQD arrays. There is usually both spatial and size disorder. [...]

Nano-structuring of isotactic polypropylene in presence of a self-assembling nucleating agent under defined flow conditions

Balzano L., Rastogi S., Peters G., Technical University Eindhoven, NL

Presence of additives in polymers plays an important role in physical and mechanical properties. For an example DMDBS is one of the frequently used additives in polypropylenes. The additive is used to achieve higher transparency [...]
