Portable Carbon Nanotube Biosensors
Mengmeng Xiao, Yuehua Ke, Zhi‐Yong Zhang, and co‐workers develop a multi‐functionalized carbon nanotube field effect transistor biosensor arrays with a portable data reading system for the on‐site single virus level detection of SARS‐CoV‐2. The biosensor arrays can detect SARS‐CoV‐2 virus antigens and the unamplified long chain RNAs simultaneously with a detection limit down to 0.05 copies/μL in 2 min response time using a multi‐probe strategy.
