Micelle-Type Sensor for Saccharide Recognition by Using Boronic Acid Fluorescence Amphiphilic Probe and Surfactants

Controlling molecular assembly by analytes is attractive for analytical techniques. Herein, we designed and synthesized amphiphilic boronic acid fluorescent probes (B-Nap-C8) possessing naphthaleneboronic as a saccharide recognition site alkyl chain hydrophobic moiety. We evaluated their function in relation to the or absorption intensity changes of assembled B-Nap-C8. Also, B-Nap-C8 effect co-surfactants. forms micelles recognizes fructose at pH 10. In presence surfactants, with cetyltrimethylammonium bromide (CTAB) micelle can recognize neutral pH. On other hand, sodium dodecyl sulfate (SDS) > This caused decrease apparent pKa on surface cationic CTAB micelle. The formation was confirmed TEM observation, critical concentration determined be 1.79 mM from titration measurements. From experiments, selectively selectivity saccharides not observed SDS. Thus, co-surfactant systems were found control water.
