Ultrasensitive Toltrazuril Sulfone Detection in Eggs via a AuNPs/NH₂-Ce-MOF-Enhanced Electrochemical Immunosensor

Key Points

• The aim is to develop a sensitive method for monitoring toltrazuril sulfone in eggs.
• Utilized an electrochemical immunosensor for detection.
• Employed AuNPs/NH₂-Ce-MOF for enhanced sensitivity.
• Focused on samples from livestock production.
• Successfully detected toltrazuril sulfone levels in egg samples.
• Showed potential hepatotoxic risks associated with the metabolite.
