Interestingly, the graphene electrode was not modified with any biorecognition element due to the increased variety of cytokines during the cytokine storm. However, researchers demonstrated the diagnostic capabilities of the biosensor in serum in less than 10 minutes and the biosensor was able to detect the hypercytokinemia in COVID-19 patients. reported a highly sensitive graphene based electrochemical dengue biosensor. In this study, researchers constructed the biosensor onto graphene surface, where an envelope glycoprotein domain III (cEDIII) was immobilised as biorecognition element in order to detect the anti-DENV antibodies.
