Fig. 4. Specificity test for the present biosensor for the target assay. From left to right, the samples are represented as blank, P53, K-ras, PIK3CA, BRCA1 and BRCA1 in the presence of the other interfering substances. The concentration of each interfering substance was 100 nM, whereas that of BRCA1 was 10 nM. Error bars represent the standard deviation of three parallel experiments.
