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...
The severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2)‐caused COVID‐19 pandemic has rapidly escalated into the largest global health emergency, which pushes to develop detection kits for the detection of COVID‐19 with high sensitivity, specificity, and fast analysis. Here, aptamer‐functionalized MXene nanosheet is demonstrated as a novel bionanosensor that detects COVID‐19. Upon binding...
