Silver/graphene–polypyrrole composite for levosimendan detection

This study used a facile method to develop a novel silver/Graphene–polypyrrole (Ag/G–PPy)‐modified electrode that can be used as an electrochemical sensor for levosimendan detection.

Description
Summary:This study used a facile method to develop a novel silver/Graphene–polypyrrole (Ag/G–PPy)‐modified electrode that can be used as an electrochemical sensor for levosimendan detection. The properties of the synthesized Ag/G–PPy‐modified electrode were examined through field‐emission scanning electron microscopy, x‐ray diffraction, and transmission electron microscopy. The Ag/G–PPy‐modified electrode exhibited satisfactory current signals toward levosimendan concentrations ranging from 0.21 to 6.88 μM and exhibited a low detection limit (0.12 μM). Accordingly, the proposed electrode can serve as a simple and inexpensive electrochemical sensor for levosimendan detection.
