▎ 摘　　要

NOVELTY - Sensor for detecting virus particles, comprises a substrate (104), a field effect transistor (FET), the FET comprising source electrodes (106) and drain electrodes (108) formed on the substrate, and a two-dimensional virus sensing transduction material (VSTM) (102) film formed on the FET, the VSTM film configured to collect a sample collected from a subject, the VSTM film comprising MXene-graphene and having a probe corresponding to the virus particles to be detected linked thereto, where a drain-source current response of the FET is representative of an amount of the virus particles in the sample for indicating an infection. USE - The sensor is useful for detecting virus particles in a sample e.g. bioaerosol, solution, and/or touch, where the virus particle comprises SARS-CoV-2 virus particles and/or influenza A (H1N1) (all claimed). ADVANTAGE - The sensor is sensitive, provides automatic and real-time sensing of influenza and SARS-CoV-2 viruses, improved robustness, and allows minimum sample preparation. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: fabricating a virus sensor; and face mask. DESCRIPTION OF DRAWING(S) - The figure illustrates MXene-graphene field effect transistor (FET) sensor. 102Ultrasensitive virus sensing transduction material 104Substrate 106Source electrode 108Drain electrodes 112Microfluid receiver
