摘要

•Pt microparticles supported on GO/GC were designed as an electrochemical sensor.•Pt/GO/GC was used in solutions that mimic the composition of biological fluids.•This Pt/GO/GC sensor was able to quantify 9 × 10-8 mol/L of epinephrine (EP).•Pt/GO/GC shows excellent sensitivity to EP even in presence of typical interferents.•Pt/GO/GC is promising as an easy-to-build sensor to EP and other catecholamines.
