Working principle of the dual-mode SERS-LFA strip for simultaneous detection of SARS-CoV-2 and influenza A virus. a Preparation of virus lysates in a nasopharyngeal solution of normal individuals. This virus solution was mixed with SERS nanotags and a running buffer solution in a 96-well plate. b N-protein antibody-conjugated SERS nanotags for the detection of SARS-CoV-2 and influenza A virus. c SERS nanotags and running buffer move toward the SERS-LFA strip by capillary force. Formation of sandwich immunocomplexes for SARS-CoV-2 (test line 1) and influenza A virus (test line 2)
