Linfield professor and physicist Michael Crosser, presented a lecture on Wednesday night in Riley Hall pertaining to his past, present, and future research called “Graphene: The Present and Future of Biosensors.”

Since 2006, Crosser has been a professor here at Linfield teaching numerous physics courses, as well as being a freshman Colloquium advisor. Aside from being a professor, Crosser has also been doing significant research on graphene.

During the lecture, Crosser demonstrated an overview of his research on graphene and how it can be used as biosensors.

Crosser’s definition of graphene was “a specific single layer of graphitic carbon.”

Professor Crosser has been working on his research for approximately 5 years and has worked in many different places such as Michigan City and currently Oregon State.

“It varies from year to year, and so does my team,” Crosser said.

Over the years, a majority of different students and physicists have helped him throughout his research of graphene.

In his studies, he compared graphene and metal by using a device that he created in a span of two weeks. In this device he ran different levels of voltage through the graphine in order to see how it reacted.

Through different tests, Crosser found out that graphine can respond to any amount of voltage given.

After numerous experiments he came to the conclusion that graphene is the thinnest of all metals.

“First we need to make sure that biosensors are reliable, but as graphene is such a thin sheet it makes it more sensitive (to the brain), and therefore it could possibly be a better solution then what we use today,” Crosser said.

Crosser hopes that his research will be the next step for the future as he believes it can one day help measure and study brain activity.
