The color gradient correlates with the biosensor signal and the antigen concentration (i.e., darker colors represent higher viral loads). The position of each antibody: CH1 – anti-IBV; CH2 – anti-RSV; CH3 – anti-IAV, and CH4 – anti-COV. For each sample (n = 46), the data represent the mean of triplicate measurements (twice using the PDMS flow cell and once using the disposable microfluidic cartridge).
