β-cyclodextrin-functionalized acetylene black nanocomposite electrode with enhanced host–guest enrichment for ultralow-level detection of niclosamide

Key Points

• To develop a modified electrode that allows for sensitive detection of niclosamide at very low concentrations.
• Utilized a β-cyclodextrin and acetylene black modified glassy carbon electrode.
• Employed differential pulse voltammetry (DPV) for detection.
• Assessed linear range and detection limit for niclosamide.
• Achieved wide linear detection range for niclosamide.
• Obtained low detection limit indicating high sensitivity.
• Demonstrated excellent selectivity in detecting niclosamide.
