AMES, Iowa – A graduate student, wrapping up a recent meeting of Jonathan Claussen’s research group at Iowa State University, reported he’s trying to get new sensors to work.
That’s a pretty good summary of the work Claussen and Carmen Gomes, both associate professors of mechanical engineering at Iowa State, have been doing for years. They’ve been inventing, making and testing sensors for agriculture, food safety and health applications.
Claussen’s lab uses heavy-duty printers to make graphene electrodes for biosensors. Gomes’ lab uses a commercial laser engraver to treat graphene and tune its properties. Visit the labs and they’ll pull out petri dishes full of their printed and laser-treated sensors.
