Novel biosensor offers rapid quantitative variant of concern-independent serology for SARS-CoV-2

Even as herculean efforts are being made to extend the reach of vaccination against COVID-19 to all the regions of the world, there is a dire need for rapid and sensitive tests to assess the antibody response to the various vaccines used and to monitor antibody titers over time. A new preprint describes a new approach to this problem which could be applied to other molecules of interest as well, both in laboratories and at the point of care.
