Transition metal coordination frameworks as artificial nanozymes for dopamine detection via peroxidase-like activity

Herein, Cu–HMT and Ni–HMT were synthesized via a green synthetic method. Cu–HMT possesses formidable peroxidase-mimic activity compared to Ni–HMT. However, the peroxidase-like activity of Cu–HMT was strongly inhibited in the presence of DA.
