A Ln-MOF Sensor Based on Dual-Signal Response and Logic Gating for the Ratio Fluorescence Detection of Anthrax Biomarkers.

Key Points

• This study aims to develop a Ln-MOF sensor for the detection of anthrax biomarkers using dual-signal response and logic gating.
• Developed a sensor utilizing Ln-MOF for fluorescence detection of biomarkers.
• Created a DPA-monitoring logic gate for enhanced sensitivity.
• Prepared a paper-based sensor combining 1-OHP and Tb-MOF@CP.
• The sensor showed high sensitivity and selectivity for DPA in serum.
• Utilized 'turn-on' and 'turn-off' mechanisms for effective detection.
• Demonstrated effective logic gating for monitoring DPA levels.
