Just touching it slightly with the tips of your fingers is enough. You can effortlessly write, navigate, open menu windows or rotate images on touchscreens. Within fractions of a second your touch is translated into control commands that a computer …
Gold 'Nanoplugs' Wire Up Enzymes
Researchers 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. The research, described in the March 21, 2003, issue of Science, may yield more sensitive, inexpensive, noninvasive detectors for measuring biological molecules, including, potentially, agents of bioterrorism.
