Abstract

Serological assays can reveal immune status against COVID-19 informing individual and public healthcare decisions. We report a multiplexed and label-free nanoplasmonic biosensor that can discriminate healthy from convalescent samples with high sensitivity (95%) and specificity (100%) based on anti-SARS-CoV-2 antibody quantification. Our results show high concordance (R~ 0.87) with commercial assays in detecting anti-SARS-CoV-2 antibodies.
