"DIGITAL-BIO: Living enzyme acts as molecular switch "
Johns Hopkins University researcher Marc Ostermeier described a single-molecule switch engineered from a strand of a living protein�an enzyme. Such molecular switchs could be applied as super-sensitive sensors that detect even a single molecule of a biological warfare agent. Medically, molecular switches have even wider-scale potential, from early detection of hard-to-diagnosis maladies, to "lethal drug" delivery only to cancerous cells.
