Gold 'nanoplugs' wire up enzymes
Scientists at Hebrew University, Israel, in collaboration with researchers at the U.S. Department of Energy's Brookhaven National Laboratory, have devised a way to use gold nanoparticles as tiny electrical wires to plug enzymes into electrodes. The gold "nanoplugs" help align the molecules for optimal binding and provide a conductive pathway for the flow of electrons.
