MXene‐Based Aptameric Fluorosensor for Sensitive and Rapid Detection of COVID‐19 (Small 23/2023)

MXene-Based Aptameric Fluorosensors The aptamer-functionalized MXene nanosheet acts as an effective bionanosensor for fluorescence-enhanced detection of COVID-19 with high sensitivity and specificity. This fluosensor is capable of detecting SARS-CoV-2 spike protein (limit of detection: 38.9 fg mL−1) and SARS-CoV-2 pseudovirus (limit of detection: 7.2 copies) within 30 min, and can also detect clinical samples.
