Cytokine Storm Biomarkers: A Flexible and Regenerative Aptameric Graphene–Nafion Biosensor for Cytokine Storm Biomarker Monitoring in Undiluted Biofluids toward Wearable Applications (Adv. Funct. Mater. 4/2021)

In article number 2005958, Zhuang Hao, Yunlu Pan, and co-workers present a flexible and regenerative aptameric graphene-Nafion biosensor for non-invasive monitoring of cytokine storm biomarkers in undiluted biofluids. The graphene-Nafion composite film minimizes the nonspecific adsorption of non-target molecules in biofluids while conferring the ability of regeneration to the biosensor. The device is shown to incur no mechanical damage during regenerative and crumpling tests.
