Comparison of selectivity of three parallel NiCo riboswtich sensors: (A), (B) FI/OD values of Ribo1 were detected by 100 μM different metal chlorides for 1 h and 4 h. (C), (D) FI/OD values of Ribo2 were detected by 100 μM different metal chlorides for 1 h and 4 h (C), (D) FI/OD values of Ribo3 were detected by 100 μM different metal chlorides for 1 h and 4 h.
