[reaction: see text] A chemically programmed antibody sensor, consisting of a stilbenyl boronic acid cofactor and monoclonal antibody EP2-19G2, provides a new method of mercury detection. The fluorescent antibody sensor generates an intense powder blue fluorescence when bound to the stilbenyl boronic acid cofactor; however, it is quenched in the presence of Hg(2+) ions. The EP2-19G2-cofactor biosensor provides micromolar sensitivity and selectivity toward Hg(2+) ions over a wide range of metal ions in aqueous solution.
