Heller Presents Nanofabrication Advances Using Nanogen Technology at Lab Automation Conference

Wednesday January 31, 1:30 pm ET

SAN DIEGO--(BUSINESS WIRE)--Nanogen, Inc. (Nasdaq:NGEN - News), developer of advanced diagnostic products, announced today that Michael J. Heller has presented results demonstrating nanofabrication applications of the company's NanoChip® technology at the LabAutomation 2007 conference in Palm Springs, Calif. Heller was a co-founder of Nanogen along with current chairman and CEO Howard Birndorf in 1993 and is now a professor of bioengineering at the University of California, San Diego.

Heller's presentation described the use of Nanogen's proprietary electronic "pick and place" technology to direct the assembly of nanoparticles in a rapid and cost-effective manner. His research team has used Nanogen's NanoChips and NC400 instrument to build multi-layered structures of nanoparticles by electronically directing the components to targeted positions on a microarray template.

"Completed structures can later be 'popped off' the template by several simple procedures. It's a unique approach to the assembly of nanoparticles into more complex structures," said Heller. "Potential applications include the production of micro-scale biosensors that may ultimately be used in the body to monitor diseases.

"There are also many uses outside of biomedical and environmental monitoring such as the manufacture of photovoltaic devices, fuel cells and batteries," he added. "It is currently very expensive to produce these devices and materials because integration of many nano and microscale components has to be accomplished. Nanogen's technology, which allows for a 'bottom up' integrated assembly, has the potential to make nanomanufacture relatively easy and cheap."

Nanogen has an extensive portfolio of intellectual property relating to integrated assembly of molecular structures through the use of electric field microfabrication technology. For licensing opportunities, contact Nanogen.

Heller's presentation was titled, "Automated Combinatorial Process for Fabrication of Multilayered Nanoparticle Structures." Additional information about the conference, sponsored by the Association for Laboratory Automation, is available at: http://labautomation.org/LA/LA07/index.php.
