Nano-Cantilevers for an Ultra-Sensitive Bio-Assay

Zheng J., Klein K., Pucha R., Sitaraman S.K., Sitaraman S.V., Merlin D., Rajalakshmi S., Sarma D.S.R., Gerwirtz A., Sitaraman S.K., Sitaraman S.V., Georgia Institute of Technology, US

Micro and Nano-scale cantilever arrays are being developed for an ultra sensitive bio-assay (Figure 1). The advantage of these cantilevers is that they eliminate the use of laser for deflection detection, which is impractical for [...]

Feasibility of Superparamagnetic Nanoparticles for Drug Delivery to the Inner Ear

Dormer K., Mamedova N., Kopke R., Liu J., Chen K., Gibson D., Jackson R., Costello M., Mondalek F., NanoBioMagnetics, Inc, US

An obstacle to effective treatment of inner ear diseases is the atraumatic delivery of therapeutics into inner ear perilymph. This study reports on the feasibility of using superparamagnetic nanoparticles as drug delivery vehicles.

NANOPOLIS: An Infrastructure for Communication in the Nanotech World

Bog D., Ciontu F., iMediasoft Group, FR

Nanopolis is a distributed knowledge network aiming at transposing today’s knowledge on matter exploration at the atomic scale into a virtual representation space. The project is focused on mitigating the impact of some of the [...]

Anticipating the Public Backlash: Public Relations Lessons for Nanotechnology from the Biotechnology Experience

Matsuura J.H., University of Dayton School of Law, US

Public concern about the safety of nanotechnology is growing. Whether rationally based, or not, that concern can impede research and commercialization in the nanotechnology industry. This risk parallels problems already encountered by the biotechnology industry, [...]

Noncovalent Engineering of Carbon Nanotube Surfaces

Chen J., Ramasubramaniam R., Liu H., Zyvex Corporation, US

Single-walled carbon nanotubes (SWNTs), due to their novel structural, thermal, electrical, mechanical and optical properties, are expected to find applications in many fields. Pristine SWNTs are generally insoluble in common solvents, and difficult to functionalize [...]

A Carbon Nanotube-Based Sensor for Measuring Forces Developed by Cells

Roman C., Ciontu F., Courtois B., Tima Laboratory, FR

We propose and validate through atomistic modeling and simulation a novel carbon nanotube-based sensor for measuring forces in the pico-Newton range, distributed over lengths ranging from nano-meters up to micro-meters. The mechanical behavior is modeled [...]

GEMS: A Revolutionary System for Environmental Monitoring

Manobianco D.M., Manobianco J., Evans R.J., Pister K.S.J., Manobianco D.M., Manobianco J., ENSCO, Inc., US

This paper describes a revolutionary, new observing system designed for environmental monitoring that will integrate MicroElectroMechanicalSystems (MEMS) and nanotechnologies. The concept, known as Global Environmental MEMS Sensors (GEMS), features an integrated system of airborne probes [...]

Converging Technologies (NBIC)

Bainbridge W.S., National Science Foundation, US

The convergence of nanotechnology, biotechnology, information technology and cognitive science can greatly improve human performance over the next ten to twenty years. The chief areas of application include: expanding human cognition and communication, improving human [...]

Nanoelectronic Devices Constructed Using Individual Vertically Aligned Carbon Nanofibers

Yang X., Austin D.W., Guillorn M.A., Merkulov V.I., Melechko A.V, Lowndes D.H., Simpson M.L., Oak Ridge National Laboratory, US

We are fabricating active nanoscale electronic devices based on Vertically Aligned Carbon Nanofibers (VACNF). VACNFs are synthesized in a high-density Plasma-Enhanced Chemical Vapor Deposition (PECVD) process that provides a high degree of control of the [...]

Nano-Electronic Sensors – Practical Device Designs for Sensors

Stetter J.R., Bradley K., Cumings J., Gabriel J-C, Gruner G., Star A., Nanomix, US

There is often a large gap between laboratory science and practical products. It will take some years to fathom the overall technical importance of nano-technology and even longer to realize societal benefits through practical products. [...]
