A pH-responsive ratiometric fluorescent probe and its application in bioimaging and food freshness monitoring

Key Points

• The aim is to develop a ratiometric fluorescent probe that can track pH changes and serve in bioimaging applications.
• Developed a water-soluble ratiometric fluorescent probe with dual-emission upon single excitation.
• Applied the probe for tracking pH changes within mitochondria and for detecting food freshness.
• Successfully created a probe that demonstrates effective pH tracking in mitochondria.
• The probe is capable of detecting changes in food freshness accurately.
