A colorimetric and electrochemical dual-mode Hg2+ sensor utilizing oxidase-like activity arising from the combination of Hg2+ and palladium metal-organic framework@graphene

Developing convenient and reliable methods for Hg 2+ monitoring is highly important. Some precious metal nanomaterials with intriguing peroxidase-like activity have been used for highly sensitive Hg 2+ detection. However, H 2 O 2 must be added during these detections, which impedes practical applica...
