Optimization of the ssDNA-MB probe concentration for the EFE electrochemical CRISPR biosensor. A) Electrochemical current of the positive and negative samples at different ssDNA-MB probe concentrations (1, 2, 5, and 10 μM) (i-iv). PC is the positive control with 500 pM HPV-16 DNA target. NC is the negative control without HPV-16 DNA target. B) Comparison of the electrochemical current difference at ssDNA-MB concentrations ranging from 1 μM to 10 μM. Error bars represent the means ± s.d. from three replicates (n = 3).
