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...
The rapid and sensitive detection of trace‐level viruses in a simple and reliable way is of great importance for epidemic prevention and control. Here, a multi‐functionalized floating gate carbon nanotube field effect transistor (FG‐CNT FET) based biosensor is reported for the single virus level detection of SARS‐CoV‐2 virus antigen and RNA rapidly with a portable sensing platform. The aptamers functionalized...
