5684 755 COF-AI-ECL The selectivity of the sensor for CAP in the presence of matrix interferences was analysed. Common veterinary antibiotics, such as tetracycline, aureomycin, oxytetracycline, doxycycline, thiamphenicol, virginiamycin, lincomycin, penicillin, amoxicillin, and florfenicol, as well as common metal ions, such as Fe2+, Fe3+, Cd2+, Al3+, Cr3+, Cu2+, Zn2+, Hg2+, Co2+, and Ca2+, were used to prepare a complex matrix sample containing CAP (5 ×10−11 mol/L), 10 antibiotics (5 × 10−8 mol/ L each), and 10 metal ions (5 × 10−7 mol/L each). The ECL responses (ΔI) to the 5 × 10−11 mol/L CAP standard sample and the complex matrix sample were similar (relative deviation < 5.0%) (Fig. S11). Using the same method, the influence of each individual interference on the ECL response was investigated. The results showed that common veterinary antibiotics and common metal ions affect the intensity of the detected signal by less than 5.0% chloramphenicol E-chem 5*10-13-4*10-10 M 1.18*10-13 M 85%-106.2%
