Highly-branched dendrite cuprous oxide films for non-enzymatic amperometric glucose sensor

Cuprous oxide (Cu2O) thin films with highly-branched dendrite structures were synthesized by electroplating through a simple stirring condition. And, the improved performance of glucose oxidation was achieved on the dendrite Cu2O film electrode. For the amperometric glucose detection, a favorable performance with a high sensitivity of 1470.8467 mu A mM(1) cm(2) and a low operating potential of 0.50 V were achieved. Thus, it would be a promising candidate electrode material for the development of non-enzymatic glucose sensors. (C) 2018 Elsevier B.V. All rights reserved.
