Enhancing the chloramphenicol sensing performance of Cu-MoS nanocomposite-based electrochemical nanosensors: roles of phase composition and copper loading amount.

The rational design of nanomaterials for electrochemical nanosensors from the perspective of structure-property-performance relationships is a key factor in improving the analytical performance toward residual antibiotics in food. We have investigated the effects of the crystalline phase and copper loading amount on the detection performance of Cu-MoS nanocomposite-based electrochemical sensors for the antibiotic chloramphenicol (CAP). The phase composition and copper loading amount on the MoS nanosheets can be controlled using a facile electrochemical method.
