Engineering of magnetic peroxidase-like heterojunction nanozymes from homogeneous iron precursor by surface-initiated encapsulation for self-calibration colorimetric/fluorescence dual-mode analysis of Hg2 + ion in foods.
The engineering of multi-modal optical sensors with improved detection accuracy is still a hot topic. Herein, the homologous heterostructured nanozyme with enhanced peroxidase (POD)-like activity was prepared by surface-initiated encapsulation of porphyrin-based metal-organic frameworks on magnetic ferroferric oxide (F...
