Graphene-Based Device Could Lead to Groundbreaking Biosensors


MSI PIs Sang-Hyun Oh (professor, Electrical and Computer Engineering) and Tony Low (assistant professor, Electrical and Computer Engineering) and their research team recently published a study of a new device that could lead to ultrasensitive biosensors. The device incorporates graphene, a material made of a single layer of carbon atoms, along with nano-sized gold ribbons. This research is the first step towards developing biosensors can could detect diseases related to protein misfolding as well as lead to improved drug-development technologies.

The study was published in the journal Nature Nanotechnology and can be found on the journal website: Graphene Acoustic Plasmon Resonator for Ultrasensitive Infrared Spectroscopy. An article about the study appears on the website of the College of Science and Engineering: New Graphene-Based Device is First Step Toward Ultrasensitive Biosensors.

Professor Oh uses MSI for a number of projects related to developing nanostructures for biosensing and photonics. Research by his group was featured on the MSI website in May 2016: A New Method to Detect Single Molecules. Professor Low uses MSI for projects studying the electronic and optical properties of 2D materials.
