Graphene biosensors focus of Linfield faculty lecture

Michael CrosserMichael Crosser, associate professor of physics at Linfield College, will present “Graphene: The Present and Future of Biosensors,” on Wednesday, Oct. 21, at 7 p.m. in 201 Riley Hall at Linfield.

Crosser will discuss research he has conducted on graphene, which is a single atomic layer of graphite. For the past four years, Crosser has studied the transport properties of graphene, using the material to make sensors.  Recently Crosser has collaborated with Ethan Minot, an associate professor of physics at Oregon State University, and his graduate student Morgan Brown, a 2002 Linfield graduate who is currently completing a Ph.D. in material science.

“Graphene, in the presence of electrical signals, will change in a reproducible way,” Crosser said. “Biological cells talk to each other through electrical impulses, so graphene promises to be a good biosensor to detect their activity.”

Crosser, at Linfield since 2006, has worked with a number of Linfield students on the project and devoted his fall 2014 sabbatical to the project. He holds a bachelor’s degree in physics and mathematics from Centre College, and a Ph.D. in physics from Michigan State University — East Lansing.

The lecture is free and open to the public. The Linfield College faculty lecture series offers one presentation each month by a member of the Linfield faculty. For more information, call 503-883-2409.
