Design of β-CD–surfactant complex-coated liquid crystal droplets for the detection of cholic acid via competitive host–guest recognition†
Abstract
β-CD–C14TAB complex-coated 5CB droplets are designed by the adsorption of β-CD–C14TAB complexes at the 5CB/aqueous interface. We show that the 5CB droplets can be used as an optical probe for the selective detection of cholic acid in aqueous solution containing uric acid and urea via competitive host–guest recognition.
