Abstract

Cubic boron nitride (cBN) film-based sensors for detecting Hg²⁺ ions were developed by surface functionalization with dansyl chloride. To immobilize dansyl chloride, 3-aminopropyltriethoxy silane was modified on hydroxylated cBN surfaces to form an amino-group-terminated self-assembled monolayer. The covalent attachment of the amino groups was confirmed by x-ray photoelectron spectroscopy. The selectivity and sensitivity of the sensors to detect diverse metal cations in ethanol solutions were studied by using fluorescence spectroscopy, revealing a great selectivity to Hg²⁺ ions. Significantly, the dansyl-chloride-functionalized cBN film sensors were recyclable after the sensing test. © 2009 American Institute of Physics.
