Schematic illustration represents the AuNP-based strips for the colorimetric detection of severe acute respiratory syndrome (SARS). Strips are coated with antibodies (Abs) that are capable of binding to viral antigen (Ag) of SARS-COV-2, that subsequently aggregate with AuNPs-conjugated secondry Abs. This aggregation results in color reaction, indicating the positivity of the tested sample
