Selective Heating Characterization of Nanoplate Devices for Simultaneous Sensing of Multiple Biomolecule Species at Ultra-low Concentrations

Elibol O.H., Reddy_Jr. B., Bashir R., Purdue University, US

We propose a novel scheme for the en masse fabrication and selective functionalization of field effect silicon nanoplate devices to enable the ultrasensitive, simultaneous and label-free detection of multiple biomolecular species in real time. The [...]

In-Plane Transduction of Nanomechanical Microcantilever Motion To Enable Sensor Arrays

Nordin G.P., Kim S., Noh J., Qian Y., Brigham Young University, US

We have recently introduced a new microcantilever transduction mechanism that is designed to scale to large arrays on a single chip while maintaining a very compact form factor and high sensitivity. It is based on [...]

A Line Force Model to Measure the Strength of Polydimethylsiloxane (PDMS)-to-PDMS Bonding in Blister Tests

Lin P-T, Lu Y-W, Rutgers University, US

Bonding is an important technique in microelectronics and Microelectromechanical Systems (MEMS). Especially, bonding two pieces of polydimethylsiloxane (PDMS) to make micro devices was widely used in micro actuators and BioMEMS. The PDMS bonding, however, lacked [...]

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 [...]

Nanostructured Polymeric Composites for High Performance Applications

Calhoun M., Allie A., Allie L., Allie A., Allie L., Aglan H., Dennig P., Tuskegee University, US

Nanostructured polymeric systems can mitigate some of the severe limitations of conventional polymeric composites. In the present research, nanocomposites of epoxy resins have been synthesized and evaluated. Organically modified layered silicate (OLS) particles and multiwalled [...]

Photogeneration Kinetics of Ag Nanoparticles in Light Sensitive Polymer Films

Korchev A.S., Foti K., Sartin M., Slaten B.L., Gale W., Mills G., Auburn University, US

Ag nanoparticles were generated within light-sensitive films composed of poly(ether ether)ketone, SPEEK and poly(vinyl alcohol), PVA. The benzophenone (BP) groups of SPEEK act as sensitizers; excited states of these functions abstract H-atoms from PVA forming [...]

Properties of Paraffin Wax/Montmorillonite Nanocomposite Coatings

Pu G., Wang J., Severtson S.J., University of Minnesota, US

Results are reviewed from a study aimed at enhancing the performance of paraffin wax based materials for barrier coating applications. Nanocomposites prepared by ultrasonic processing from paraffin wax matrices and reinforced with organically modified montmorillonite [...]

The Effect of POSS Compatibility on the Morphology of Thiol-ene Polymer Nanocomposites

Clark T., Hoyle C., Nazerenko S., University of Southern Mississippi, US

The physical properties of thiol-ene/POSS nanocomposites are measured and used to indicate the morphological changes of the materials as a function of POSS concentrations. Vinyl POSS monomers are modified with various organic pendants using an [...]

Conducting Polymer Nanocomposites: The Role of the Electronic Fingerprint of Carbon Nanotubes

Chiu P.L., Ma Y., Serrano A., Wang L., Mendelsohn R., He H., Rutgers University, US

In this presentation, we report that dispersion and functionalization of single-walled carbon nanotubes (SWNTs) with different dispersing methods and dispersing agents result different SWNTs with different electronic structures and surface chemistries. In-situ polymerization of the [...]

Nano-Tecture: Developing Smart Skins in Architecture

Ataman O., Trautmann J., University of Illinois at Urbana-Champaign, US

This paper surveys a brief history of architectural skin materials and presents an ongoing research project about the development of the materials and fabrication concepts for a fundamentally new class of architectural composite. This type [...]
