A Synergistic Cetyltrimethylammonium Bromide (CTAB)/Multiwalled Carbon Nanotubes–β‐Cyclodextrin (MWCNT–β‐CD) Platform for Enhanced Electrochemical Detection of Bisphenol A

open access: yesAdvanced Sensor Research, Volume 5, Issue 3, March 2026.
CTAB/MWCNT–β‐CD/SPCE enables ultrasensitive and selective detection of BPA. Hydrophobic microdomains from CTAB tails, MWCNTs, and β‐cyclodextrin cavities preconcentrate BPA. Positively charged CTAB heads improve wettability and mass transport, allowing efficient electrochemical oxidation at 0.6 V with minimal interference from phenolic and biomolecular
