Non-Silicone Based Nano Thickness Coating to Improve Protein Compatibility

Yeh R., Ling M.T., Baxter Healthcare Corportation, US

Medical devices have relied to a large extent on silicone oil surface treatment. A drawback of silicone oil is that it may induce aggregation of proteins in vivo or in vitro. The conformational change of [...]

Self Assembly of Colloidal Gold Nanoparticles on Diblock Copolymer Thin Film Templates

Adams S.M., Ragan R., University of California Irvine, US

Self-assembly of metallic nanoparticles were investigated for the development of field-enhanced chemical and biological detection devices with the capacity to achieve single-molecule level detection resulting from surface enhanced Raman scattering, associated with closely spaced noble [...]

Tunable Wetting of Titanium and Gold Based Wicking Materials

Ding C., university of california, santa barbara, US

We quantitatively report the experimental super-wetting results of wicking materials fabricated with bulk titanium micromachining, nano-scale surface modification and gold plating techniques. The results show all the four samples are completely wettable with water but [...]

Durable Super-Hydrophobic Nano-Composite Films

Chinn J., Integrated Surface Technologies, US

A new durable super-hydrophobic coating has been invented that protects cell phones and other portable electronic products from water or other liquid damage. The printed circuit boards of these consumer oriented products are placed into [...]

Superhydrophobic coating using metallic nanorods for aerospace applications

Kannarpady G.K., Lefrileux Y., Laurent T., Woo J., Khedir K.R., Ishihara H., Trigwell S., Ryerson C., Biris A.S., University of Arkansas at Little Rock, US

The paper presents a novel technique that combines anodization and glancing angle sputtering deposition to generate nanorods of Aluminum. The nanorod surface coated with a monolayer of a silane exhibited contact angle of 155 degree [...]

Development of Durable Nanostructured Superhydrophobic Self-Cleaning Surfaces in Glass Substrates

Jiang Y.D., White M., Hunt A.T., Kitada M., Fitz T., nGimat Co., US

Superhydrophobic self-cleaning surfaces have wide applications in architectural and automotive windows and solar panels, etc. Many existing hydrophobic coatings either have low transmittance which is not suitable for windows or not as hydrophobic as lotus [...]

Biofouling control coatings utilizing VOC free biodegradable chitothane and nanotubes containing non-toxic natural product repellents

Price R.R., Matias J., Glen Muir Technologies, Inc., US

Novel water based biofouling control coating based on natural marine polysaccharides and novel naturally occuring nanoscale microcylinders for the delivery of natural antifouling repellent analogs for control of biofouling on surfaces.

Adhesion of Water on Flat Polymer Surfaces and Superhydrophobic Surfaces

Law K-Y, Zhao H., Samuel B., Xerox Corporation, US

The interaction of water droplet with flat polymer surfaces of varying hydrophobicity (contact angle) has been studied using a high-sensitivity microelectromechanical balance system (tensiometer). Both attractive force and pull-off force are studied as the water [...]

Fabrication of size-tunable gold nanoparticles using plasmid DNA as a biomolecular reactor

Samson J., Piscopo I., Yampolsky A., Nahirney P., Parpas A., Toschi A., Drain C.M., Hunter College of CUNY, US

Plasmid DNA has proven to be a successful template/mold for the formation of metallic nanoparticles because it is readily available, inexpensive, and malleable i.e. it can exist in different topologies. Using different plasmid DNA species [...]

Electron instabilities in nanoclusters, nanostructures and inhomogeneous nanomaterials: bottom up approach

Kocharian A., California State University Los Angeles, US

Inhomogeneous nanomaterials with strong local electron correlations are creating a new world-view in condensed matter physics [1-4]. These materials with intrinsic ihomogeneities have electronic and magnetic properties that are widely different from the conventional materials. [...]
