Excellent adsorption selectivity of SiO2@PEI@AZ/PEG: Fluorescence of aqueous pyrene after adsorption with SiO2@PEI@AZ/PEG in the absence/presence of bromodecane, toluene, benzene, sodium dodecyl sulfate (SDS).
Conditions: pH 7.4 (buffer); λex = 335 nm; [pyrene] = 137 ppb; [PEI@ AZ/PEG] = 1.5 × 10−5 M; [SDS] = 5 × 10−4 M; equilibrating for 24 h before fluorescence measurement; the fluorescence of neat pyrene alone is also presented for reference.
