Selective interaction of As( iii ) and luminol for the development of electrochemiluminescence-based arsenic( iii ) sensors

Key Points

• To investigate the selective interaction between arsenic(iii) and luminol for ECL sensor development.
• Identified interaction mechanisms between arsenic(iii) and luminol
• Analyzed ECL signal amplification due to 3-aminophthalate formation
• Developed sensors based on the interaction for arsenic(iii) detection.
• The interaction between As(iii) and luminol significantly amplifies ECL signals
• Formed excited 3-aminophthalate enhances detection sensitivity
• Demonstrated potential for more effective arsenic(iii) sensors.
