New graphene-based device is first step toward ultrasensitive biosensors

08.03.2019 | University of Minnesota | cse.umn.edu

Researchers in the University of Minnesota College of Science and Engineering have developed a unique new device using the wonder material graphene that provides the first step toward ultrasensitive biosensors to detect diseases at the molecular level with near perfect efficiency.

Ultrasensitive biosensors for probing protein structures could greatly improve the depth of diagnosis for a wide variety of diseases extending to both humans and animals. These include Alzheimer’s disease, Chronic Wasting Disease, and mad cow disease—disorders related to protein misfolding. Such biosensors could also lead to improved technologies for developing new pharmaceutical compounds.

Ultrasensitive biosensors

In this new study, University of Minnesota researchers combined graphene with nano-sized metal ribbons of gold. Using sticky tape and a high-tech nanofabrication technique developed at the University of Minnesota, called “template stripping,” researchers were able to create an ultra-flat base layer surface for the graphene.
