Rapid detection of pathogenic bacteria in food by a label-free electrochemical sensor based on PCN-224 modified electrode

Key Points

• The electrochemical sensor successfully detects pathogenic bacteria levels in food samples, enhancing food safety.
• Key evidence shows that this sensor achieves detection limits as low as 0.1 CFU/mL for various bacteria.
• Analysis using a label-free approach demonstrates the effectiveness of the PCN-224 modified electrode in this application.
• This innovative method may enable rapid testing for foodborne pathogens, improving public health efforts against food contamination.
