美国加拿大一直开放这种快速测试,渥太华还有一个华人公司好像号称成功,结果后来没有下文。
Rapid and ultrasensitive electromechanical detection of ions, biomolecules and SARS-CoV-2 RNA in unamplified samples - Nature Biomedical Engineering
A self-assembled DNA-based system immobilized on a liquid-gated graphene field-effect transistor can electromechanically detect ultralow levels of unamplified ions, nucleic acids, small molecules and proteins in biofluids.
