Fig. 6: SWV response of MXOF for Selectivity and stability.

a Different analytes, trimethoprim (TMP), tetracycline (TET), chloramphenicol (CHR), L-ascorbic acid (ASC) are used to determine the interference with 10-fold to the (sulfamethoxazole) SMX concentration. The current responses are around 12.03, 33.1, 49.8, 52.4, 69.52 µA of TMP, TET, SMX, CHR and ASC, respectively. b The stability of the MXOF electrode is between 49.8 to 42.3 µA for 4 weeks observed analysis.
