Fig. 3. Selectivity test. (A) Fluorescent images of the biochips show the cross-reactivity tests by depositing (i) only E. coli O157:H7, (ii) S. typhimurium, (iii) L. monocytogenes, (iv) E. coli O157:H7 and S. typhimurium, (v) E. coli O157:H7, S. typhimurium, and L. monocytogenes of each cell concentration of 105 CFU mL−1, (vi) without bacteria cell (B) Fluorescence intensities were obtained for each pathogen deposited for the selectivity tests. Error bars show ± 1 std. dev. (n = 10).
