An ultra-sensitive electrochemical sensor based on MOF-derived ZnO/Co3O4decorated on graphene for low-level monitoring of the α1-AR antagonist alfuzosin in tablets and human samples

We present a novel electrochemical sensor for the detection of alfuzosin (AFZ), an alpha1-adrenoceptor (α 1 -AR) antagonist using metal–organic framework (MOF)-derived zinc oxide/cobalt oxide (ZnO/Co 3 O 4 ) decorated on graphene (Gr).
