New Graphene Biosensor to Detect Cancer Biomarkers
The biosensor, which can detect the oxidative stress marker 8-hydroxydeoxyguanosine, is 5-times more sensitive than the ELISA test that is commonly used to identify biomarkers.
An ultrasensitive biosensor made from the wonder material graphene has been used to detect molecules that indicate an increased risk of developing cancer.
The biosensor has been shown to be more than five times more sensitive than bioassay tests currently in use, and was able to provide results in a matter of minutes, opening up the possibility of a rapid, point-of-care diagnostic tool for patients.
The biosensor has been presented today, 19 September, in IOP Publishing's journal 2D Materials.
To develop a viable bionsensor, the researchers, from the University of Swansea, had to create patterned graphene devices using a large substrate area, which was not possible using the traditional exfoliation technique where layers of graphene are stripped from graphite.
