Graphene may be used for advanced detection of early-stage lung cancer in the future according to researchers at the University of Exeter.
The “supermaterial” graphene may be the key to advanced detection of early-stage lung cancer in the future, according to researchers from the University of Exeter, United Kingdom. They recently developed a highly sensitive graphene biosensor that can detect common lung cancer biomarkers, and published their results in Nanoscale.
Cancer-marker (CM) monitoring is a promising area wherein researchers hope to detect the CMs present in exhaled volatile organic compounds (VOCs) that are emitted during breathing. These VOCs essentially comprise a “breath-print.”
“Diagnosis of lung cancer or any type of disease through a non-invasive e-nose approach can guarantee a practical and reusable method of complex monitoring of VOCs in the human breath.
In this work, we report the feasibility of bare multi-layer graphene (MLG) as a proof of concept for the e-nose technologymulti-layer graphene,” wrote co-author Ben Hogan, postgraduate researcher, University of Exeter, and fellow researchers.
“The new biosensors which we have developed show that graphene has significant potential for use as an electrode in e-nose devices. For the first time, we have shown that with suitable patterning graphene can be used as a specific, selective and sensitive detector for biomarkers.
We believe that with further development of our devices, a cheap, reusable and accurate breath test for early-stage detection of lung cancer can become a reality,” added Hogan.
In medicine, particularly, the potential of graphene is impressive. For example, small machines and sensors made of graphene can move effortlessly throughout the body, to analyze tissues and even deliver drugs to targeted areas, all without causing harm….
They are hopeful that their discovery will pave the way for new and improved e-nose devices capable of detecting lung cancer much earlier than previously possible.
