4分钟出检测结果，复旦大学团队研发出新冠检测新设备和方法 - 2022年02月11日

Chinese scientists have developed a molecular system that can provide COVID-19 testing results in less than four minutes.

A research team from Shanghai-based Fudan University mentioned this portable prototype device in a study published recently in the journal Nature Biomedical Engineering, saying it can detect the traces of COVID-19-related genetic material quickly and accurately.

The device is an electromechanical biosensor consisting of a probe bound to a flexible single-stranded DNA cantilever that is linked to a self-assembled stiff double-stranded DNA structure, according to the study.
