Nanozyme-based detection of SARS-CoV-2. A Schematic illustration of the Co–Fe@hemin nanozyme chemiluminescent paper test for SARS-CoV-2. B Screening of paired antibodies using a Co–Fe@hemin nanozyme colorimetric strip. A positive signature was rated by 100 ng/mL of S-RBD protein. C A protocol for detecting SARS-CoV-2 using the CRISPR‒Cas12a system based on the ssDNA-MnO2-MB reporter. D Detecting differing levels of SARS-CoV-2 E pseudovirus based on the RPA-conjugated MnO2 nanozyme-mediated CRISPR‒Cas12a system.
