Specificity of the passively driven chip detection system: (A-H) Representative fluorescence detection signals and passively driven chip results for individual viruses: (A, B) SARS-CoV-2 (COVID-19), (C, D) human parainfluenza virus (PIV), (E, F) influenza A virus (IAV), and (G, H) influenza B virus (IBV). (I) Fluorescence detection signal and (J) passively driven chip results for the multiplex detection of IAV and IBV viruses in a mixed sample. (K) Fluorescence detection signal and (L) passively driven chip results for the multiplex detection of all four viruses (SARS-CoV-2, HPIV, IAV, and IBV) in a mixed sample.
