Abstract
One aspect of the present invention relates to reactive compositions and methods of use thereof, wherein a metal oxide cluster is used to connect a reactive group (or groups) to the surface of a substrate. In certain embodiments, the reactive group in the compositions decomposes organophosphate agents through nucleophilic hydrolysis. In certain embodiments, the reactive group in the compositions is bactericidal. Remarkably, the use of metal oxide clusters in the disclosed compositions and methods permits incorporation of higher quantities of nucleophilic and bactericidal groups without the difficulties associated with having to pretreat the substrate prior to its association with the reactive groups.
