摘要

•CuO-SWCNT was fabricated via a quick-precipitation method.•CuO-SWCNT-PDDA was fabricated via electrostatic interaction strategies.•Electrochemical nonenzymatic sensor was fabricated based on CuO-SWCNT-PDDA/GCE.•H2O2 reduction peak was increased due to the synergic effect of CuO-SWCNT.•The sensor coupled with amperometric was applied in commercial foods.
