Keggin polyoxometalates based hybrid compounds containing helix/nanocages for colorimetric biosensing

Two new Keggin polyoxometalates (POMs) based hybrid compounds containing helix/nanocages as peroxidase-like mimics have been synthesized and structurally characterized, which exhibit higher peroxidase-like catalytic activities, broader applications range, faster respond time and lower detection limit compared with other POMs involved peroxidase-like mimics.432
