Highly Selective Monolayer Sorbents for Advanced Analytical Applications


EMSL Project ID
3604

Abstract

Molecular templating of self-assembled monolayers on a mesoporous silica may be used for highly selective detection of relatively small molecules. By using different templating processes and a variety of functionalities on the monolayer, the substrate may be made selective for nearly any chemical. When the chemical binds to the active site on the surface of the mesoporous material, the site may be made to fluoresce. Both scanning fluorimetry and time-resolved laser induced fluorimetry will be used to identify and categorize site selectivity and binding ability of a variety of chemicals on an active substrate. This work will result in several manuscripts and advance methods for detection of environmental contaminants or weapons of mass destruction.
