Comparison of calibration curves for a SARS-CoV-2 and b influenza A virus, determined by the measurement results of ELISA and dual-mode SERS-LFA. Each calibration curve was determined using a four-parameter sigmoidal fitting equation (black: ELISA, purple and red: SERS-LFA). The y-axis represents the optical density for ELISA and the Raman scattering intensity ratio of the test and control lines for SERS-LFA
