Inthatscience fictionfuture, vats ofvirus-proof mirror cellscould pump out biofuel, lay down nano-sizeorganiccircuitry, and even extrude organic cement foundations for skyscrapers.
We're not exactly sure what makes these virus transistors so special, but apparently the transistors they've built out of the nano-coated strands, and sandwiched between two electrodes, are easy to switch between ON and OFF states, since they don't need to build up a charge at a lame-o capacitor before they can be switched.
