摘要

Quick and robust analytical methods are of vital necessity in medicine and biology, making the synthesis of electroactive substrates for the sensing of medically relevant chemicals, a promising area of material science. Rare-earth cuprates, mostly famous for high-temperature superconductivity, continue to exhibit encouraging electroactivity towards surface selective oxidation of biologically active compounds. Samarium cuprate reported in this paper showed developed surface with unique porous morphology and good conductivity––a set of prerequisites for the sensing material. Further studies confirmed excellent samarium cuprate-based carbon paste-electrode sensitivity of enalapril maleate and helped to develop an analytical method with selectivity and stability applicable for wider use.

Graphical abstract

Sintering of equimolar amounts of copper and samarium oxides provides crystalline samarium cuprate at the temperature below its melting point. Obtained material has developed surface with micron-size pores. Further electrochemical studies as an additive in carbon paste, confirmed its excellent activity towards hypertension drug sensing.
