Specificity of the detection with SPR biosensor. A) Hybridization of PCR products of S. aureus. A total of 50 nM of the PCR products of S. aureus were incubated with four different probes: a specific probe (black column), a 5'-end single-base mismatch probe (red column); a middle single-base mismatch probe (green column); a 3'-end single-base mismatch probe (blue column). * P < 0.05 vs other three single-base mismatch probes. B) Hybridization of a mixture of PCR products from four bacteria with four specific probes.
