Spinel Zn3V3O8 nanosheets via a one-step hydrothermal synthesis with peroxidase-like activity for high sensitivity glucose colorimetric detection in synthetic perspiration

Hydrogen peroxide reacts with V⁴⁺ on (011) exposed facet of 2D Zn₃V₃O₈ nanosheets to produce a hydroxyl radical via a Fenton-like reaction and its peroxidase-like activity is applied to glucose colorimetric detection.
