electrical engineering
cagapakis | September 6, 2010A lot of synthetic biology is about getting biology to be more like electrical engineering, designing genetic "logic gates" to create a living circuit board. Beyond analogies, however, cells have many fascinating electrical properties--proteins that transfer electrons like wires, membranes that separate ions and create an electrical charge that drives the metabolism of the cell, channels through these membranes that open and close to activate an electro-biological response. Electrons are electrons whether they are in proteins or copper wires, and many scientists have designed ways to connect…
