Novel photo-responsive deep eutectic solvents: preparation, characterization, and application in detecting organophosphorus chlorpyrifos pesticide residues in apples and grapes

Key Points

• The central aim is to develop and evaluate a novel photo-responsive deep eutectic solvent for detecting chlorpyrifos residues in fruits like apples and grapes.
• Developed a novel photo-responsive deep eutectic solvent (PR-DES) for detection.
• Characterized the PR-DES properties using various techniques.
• Applied the PR-DES for detecting chlorpyrifos residues in fruits.
• The PR-DES effectively detected chlorpyrifos residues at low concentrations.
• The detection method showed high sensitivity and accuracy for both apples and grapes.
