Graphene-enhanced COVID-19 sensor detects virus in seconds

The graphene-enhanced sensor, says the company, supports the fastest and easiest to use rapid COVID-19 virus detection test kit and is the only of its kind saliva test – eliminating the nasopharyngeal swab and all certified practitioner oversight requirements, and does not require expensive equipment, and there is no cross handling which increases cross contaminations. The GLCM test directly detects the virus, ensuring no false positive/negative results, unlike other tests which detect only the byproducts of infection and are therefore unreliable.

“Graphene is the ideal sensing material,” says Jason Deacon, Product Development Lead of GLC-GLCM. “The 2D nature and conductive attributes of graphene make for an extremely sensitive material to detect any molecule. At GLC-GLCM, we have made the surface highly specific to SARS-CoV-2 (COVID-19) to ensure that our rapid test will save lives.”

GLCM’s COVID-19 point-of-care test, says the company, offers a unique advantage over other tests as it detects the presence of the COVID-19 virus. Competitive tests that have been announced are predominately nucleic acid tests and serological assay tests.

The serological assay tests are designed to identify IgM and IgG antibodies that are present post infection, while nucleic acid tests identify active infection, but still require the use of the nasopharyngeal swab and results must be interpreted by a certified practitioner using expensive equipment, which is a slow-moving process. In addition, both the serological and the nucleic tests produce false positive and false negative results, whereas GLCM’s test has been developed to indicate a positive result only when the COVID-19 virus is present, allowing for direct and clear interpretation by the user.

GLCM says it has completed development of the graphene-enhanced sensor used in the rapid test kit, which is an in-vitro diagnostic device that produces a signal when exposed to COVID-19 viral antigens. With the achievement of the positive identification of the viral antigens, the company has begun development of a functional prototype of the rapid response test.

“The success of this development offers the world a solution for COVID-19,” says Donna Mandau, President & CEO for GLC-GLCM, “and as our graphene is tailorable, we can offer a fast solution to future virus’ in rapid modification of our graphene which will ensure we do not relive the major economic shutdown as experienced with COVID-19. The inspiration for all of us at GLC-GLCM is to offer our graphene solutions for People and Planet. This rapid test brings family and friends together for times of joy free from fear of COVID-19. This test also brings family together in those times that we need to say good-bye to a loved one. No one should have to die alone again.”

Its rapid test, says the company, is an “at the door” technology that is perfect before boarding a plane, or entering a venue for a concert or sporting event, as it delivers instant results for regaining confidences to help “bring us back to our ‘normal’ before the pandemic.”

The company says it is advancing discussions with manufacturers and governments in several countries in order to facilitate production protocols reflective of their country’s government regulatory compliance requirements. GLCM expects to benefit from expedited regulatory and clinical-testing requirements as announced by several regulatory agencies including Health Canada and the United States’ FDA.

“The study of 2D materials has been encased in academia for 15 years.” says Deacon. “Our team at GLC-GLCM believes that nanotechnology regarding 2D materials is critical to future technology and innovation, with graphene at the forefront.”
