(13.2 times higher than that of the unmodified electrode), respectively. The developed sensor also exhibited high reproducibility (RSD = 2.61%), good stability (RSD = 6.47%) after 7 days, and good selectivity towards CA. Real sample tests using apple juice showed good recovery (92.2-98.4%). Further studies will be conducted in the near future to better understand the growth mechanism of the MOF films, control their morphology and utilize them in other electronic applications.
