Back Cover: Amplification‐Free Detection of SARS‐CoV‐2 and Respiratory Syncytial Virus Using CRISPR Cas13a and Graphene Field‐Effect Transistors (Angew. Chem. Int. Ed. 32/2022)

ABSTRACT

Nucleic acid detection plays a critical role in medical diagnostics, environmental monitoring, and food safety. In their Research Article (e202203826), Xue Gao, Yi Zhang and co‐workers developed a new biosensor for amplification‐free nucleic acid detection via harnessing the trans‐cleavage mechanism of Cas13a and ultrasensitive graphene field‐effect transistors (gFETs). The illustration shows the Cas13a‐mediated RNA trans‐cleavage on a gFET surface for sensor signal transduction.
