Specificity analysis of the MXene-AuNPs assisted MoECS biosensor for Omicron BA.5 variant

The intensity was calculated based on the square wave voltammetry current with the addition of the target BA. 5 variant RNA (1 nM) and RNA templates from different viruses (1 nM). The dash line represents the threshold for a positive signal. Error bars represent standard derivation obtained in three parallel experiments
