Preliminary analysis of detection sensitivity. Representative results from serial dilution experiments for influenza A, B, human parainfluenza virus, and SARS-CoV-2 are shown. (A, C, E, G) Fluorescence detection signals. (B, D, F, H) Corresponding results from the passively driven microfluidic chip. The viral template inputs for each row, from top to bottom, were 1 × 103, 1 × 102, 1 × 101, and 1 × 100 copies/µL. NCT: negative control.
