Research Interests

Our research interests are fosused on applying chemical rules to extend the function of proteins and nucleic acids.

One way is to attach nanometer-diameter semiconductors (quantum dots) to proteins, where protein-ligand interactions control the fluorescence intensity of the quantum dot. We are currently examining the fluorescence properties of single protein-quantum dot assemblies using fluorescence microscopy. Our ultimate goal o this work is to generate fluorescent sensors to detect fluxes of molecules withing living cells.

A second interest is to introduce novel metal binding sites into proteins of known structure. This work has generated novel analytical tools [cytosolic Pb(2+) ion sensors] and enzyme mimicks [superoxide dismutase]. We are currently refining the Pb(2+) ion sensor proteins for improved sensitivity and selectivity in biological media.
