Platinum/palladium-enhanced Cu-Cu2O nanozyme grown on manganese sheet for efficient peroxidase-like catalysis and sensitive colorimetric ampicillin detection

Key Points

• Efficient peroxidase-like catalysis is achieved with the platinum/palladium-enhanced Cu-Cu2O nanozyme.
• This method shows a high sensitivity for detecting ampicillin at lower concentrations.
• Catalytic activity is optimized using a manganese sheet for enhanced nanostructure.
• The findings may enable rapid and sensitive testing for antibiotics in various settings.
