Fluorescence and colorimetric dual-mode sensor based on red-emitting chiral carbon dots for discrimination of serine enantiomers and basic amino acids

Key Points

• Discrimination of serine enantiomers occurs effectively with the dual-mode sensor, enhancing detection capability.
• This sensor demonstrates a notable peak shift in fluorescence at 620 nm, with significant differences in response for different amino acids.
• Analysis of sensor responses indicates that both fluorescence and colorimetric methods are effective for detecting serine and other amino acids.
• The findings highlight the potential for using these chiral carbon dots in further amino acid sensing applications.
