Comparison of SERS-based assay for SARS-CoV-2 detection performed in (a) a microtube and (b) a microdroplet sensor. In the assay using a microtube, SERS signals were measured at five different positions of the capillary tube. The signal of 140 droplets passing through the focal volume was measured and averaged in the microdroplet sensor. (c) Comparison of CV values of the assays performed using two different methods for the detection of SARS-CoV-2.
