Flower-like Cu/Ag nanozyme as oxidase-mimic for the colorimetric detection of hydroquinone

Key Points

• Colorimetric detection of hydroquinone was achieved using a flower-like Cu/Ag nanozyme.
• The detection method displayed sensitivity and selectivity with limits of detection at nanomolar concentrations.
• Assessment using synthesized nanozymes demonstrated their effectiveness as oxidase-mimics in color changes.
• Novel detection approaches could enhance environmental monitoring for harmful substances like hydroquinone.
