A novel modified electrode based on terbium oxide and carbon nanotubes for the simultaneous determination of methyldopa and paracetamol

A novel voltammetric sensing platform was prepared ultrasonically by modifying a glassy carbon electrode (GCE) with a composite of terbium oxide (Tb₄O₇NPs) nanoparticles and carbon nanotubes (CNTs) for the simultaneous determination of methyldopa (MD) and paracetamol (PR).
