title: A supramolecular off-on fluorescent switch and IMPLICATION logic gate for detection of cationic surfactant.
abstract: A supramolecular system was used to detect cationic surfactant CTAB in aqueous solution through the fluorescence indicator displacement mechanism. The dynamic detection range and the detection limit of cationic surfactants can be adjusted by altering the initial concentration of receptor. Furthermore, a three-input IMPLICATION gate was achieved with SDS, CTAB and temperature as inputs.
