Microscopic sea creatures provide foundation for gas sensors and other devices

illions of years old, obtained from samples mined and distributed as diatomaceous earth. To provide samples with other geometries, Sandhages group has set up a cell culturing lab, with the assistance of Georgia Tech colleagues Nils Krger and Nicole Poulson, to grow the brownish-colored diatoms.

Sandhage, who is a ceramist by training, would now like to work directly with electronics engineers and others who have specific interests in silicon-based devices.

"We can target diatoms of a certain shape, generate the right chemistry, and then work with applications engineers to get these unique structures into practice," he said. "We are now at the point where we have a good idea of the chemical palette that is accessible with the conversion approaches we have taken. The next step is really to start making packaged devices."
