Comparison of the qPCR and MoECS on testing the clinical samples. (a) After identifying with qPCR and Sanger sequencing, eight healthy samples, eight BA.2 samples and eight BA.5 samples were categorized. (b) MoECS test were performed on the categorized samples, electrodes targeting the N gene showed a highly correlated signal with qPCR results. Moreover, for the electrodes targeting the L452R mutation, signals were only observed in BA.5 samples
