Emeryville, California - November 30, 2004 - Nanomix, Inc. a leading nanotechnology company was an invited speaker at The 2004 Materials Research Society Fall Meeting, a leading forum for scientists and engineers to exchange information and ideas at the forefront of materials research, held at Hynes Convention Center in Boston, MA. During his talk on November 30, 2004, Dr. Jean-Christophe Gabriel of Nanomix gained tremendous attention from the audience and members of the Society. His presentation was featured in the day's meeting highlights, which will be published in the MRS Bulletin.

Technical Presentations - A Sampling

The long wait for commercial carbon nanotube-based electronic devices is almost over according to Jean-Christophe Gabriel from Nanomix Inc., a California based start up that expects to be marketing single-walled carbon nanotube (SWNT)-based hydrogen sensors by early 2005. Delivering an invited talk in Symposium HH, Gabriel discussed the tremendous versatility of sensors based on carbon nanotube field effect transistors, which he compared to nerve cells capable of sensing different stimuli. While single nanotube transistors are too fragile to be useful over long periods of time, networks and arrays of nanotubes make robust sensors, while also giving high signal to noise ratios with low power consumption therefore enabling wireless application. The tremendous sensitivity of the transport properties of SWNT devices to small environmental changes is ideal for sensing applications but also requires that nanotubes be functionalized to be selective and specific for certain analytes. Metal functionalized nanotubes make for excellent hydrogen sensors capable of detecting levels of hydrogen with great sensitivity. Further applications being explored at Nanomix include a polymer functionalized SWNT sensor for CO2 and biofunctionalized nanotube sensors for biomolecule detection in liquid environments.

The Materials Research Society is a not-for-profit organization which brings together scientists, engineers and research managers from industry, government, academia and research laboratories to share findings in the research and development of new materials of technological importance. Founded in 1973, MRS now consists of more than 12,600 members from the United States -- as well as over 50 other countries. The Society is different from that of single discipline professional societies because it encourages communication and technical information exchange across the various fields of science affecting materials. MRS works closely with other materials organizations around the world, and is an Adhering Body of the International Union of Materials Research Societies (IUMRS).
