Electrochemically Exfoliated WS 2 Nanosheets for the Electrochemical Impedimetric Detection of NADH
In this work, exfoliated WS 2 nanosheets were synthesized using a two‐electrode‐configured electrochemical exfoliation method and they were used as a potential material for the detection of NADH. Using screen‐printed carbon electrodes (SPCEs) as a sensing platform, exfoliated WS 2 nanostructures (ex...
