A Beryllium-Selective Microcantilever Sensor Modified with Benzo-9-crown-3 Functionalized Polymer Brushes

Abstract

A benzo-9-crown-3 functionalized polymer brush was prepared via surface-initiated atom transfer radical polymerization on the gold surface of microcantilevers for selective detection of Be2+. Other metal ions, such as Li+, Na+, K+, Mg2+ and Ca2+ have minimal effect on the deflection response of the microcantilevers. The microcantilever sensor exhibits high sensitivity for beryllium ions with the limit of detection (LOD) to be as low as 10-10 M. The mechanism of the bending is discussed as well.
