Synergistic oxygen vacancy and multivalence in Co/Cu-ZIF/V₂O₅ nanozyme enable ultrasensitive colorimetric detection of ascorbic acid and epigallocatechin gallate
{{output}}
Sensitive detection of antioxidants like ascorbic acid (AA) and epigallocatechin gallate (EGCG) in tea is crucial for quality control. To overcome the limitations of natural peroxidases, we designed a Co/Cu-ZIF/V₂O₅ nanozyme via vanadium-doped defect enginee... ...
