Cross reaction investigation by testing S. aureus (10⁶ cfu mL⁻¹) and S. enterica (1375 cfu mL⁻¹) with their corresponding and non-corresponding aptamers. 1.0 μM specific aptamers for S. aureus and S. enterica (i.e. FASA and FASE listed in Table 1) were first immobilized in detection wells of the top two and the bottom two rows, respectively. Blank and pathogen samples were separately introduced from vertically-oriented channels.
