Electrochemical biosensor based on Cu/Cu2O nanocrystals and reduced graphene oxide nanocomposite for sensitively detecting ractopamine

Choline Oxidase Based Composite ZrO2@AuNPs with Cu2O@MnO2 Platform for Signal Enhancing the Choline Biosensors

“…Different kinds of metal oxide composite materials have been considered as a favorable choice and have attracted the attention of many researchers in the development of biosensors because of their unique physical and chemical features, such as a cuprous oxide (Cu 2 O), which offers (i) a non‐toxic semiconductor, (ii) absorber material, (iii) mesoporosity, (iv) high affinity, (v) fast electron mobility, (vi) relatively higher surface area, and (vii) unique electrochemical capability [20, 21]. Manganese dioxide (MnO 2 ) provides (i) a catalytic activity, (ii) abundant availability, (iii) absorption ability and (iv) low toxicity [22, 23].…”
