Enhanced fluorescence and heavy metal ion sensing using nitrogen-doped carbon quantum dots synthesized from banana peel waste

Puntos clave

• Enhanced fluorescence was achieved using nitrogen-doped carbon quantum dots derived from banana peel waste, showing promising results for heavy metal ion detection.
• The maximum sensitivity level reached indicates a potential decrease in detection limits for heavy metal ions, particularly lead and mercury.
• Assessment of the carbon quantum dots used fluorescence spectroscopy methods, providing insights into molecular interactions and sensing mechanisms.
• The findings may enable the development of low-cost biosensors for monitoring environmental pollutants, though further testing in complex samples is needed.
