Non-invasive detection of gastric cancer biomarker 4-HBA via a ZIF/CDs-based fluorescent sensor

Puntos clave

• Gastric cancer biomarker 4-HBA was successfully detected using a novel sensor approach.
• The approach exhibited sensitivity and specificity for detecting 4-HBA levels in biological samples.
• Fluorescent sensor based on ZIF and carbon dots was utilized for biomarker identification.
• The findings may enhance non-invasive diagnostic techniques for early gastric cancer detection.
