a Images of the RJPs on the RQC in a Salmonella detection assay with various invA concentrations (0, 0.01, 0.1, 1, 10, and 100 nM) performed using the developed optical sensing platform. b The graph shows the number of bound RJPs, which was calculated from images using Image J. c The calibration curve for the invA assay on a log scale. Linear regression analysis was performed, and the error bars are the standard deviation
