(Nanowerk News) University of Arizona engineers have patented a process that could lead to the next big leap in microelectronics, completely changing the way microchips are made.The bioengineering breakthrough patented by researchers at the UA College of Engineering is used to build microscopic wiring circuits made of copper insulated by proteins.Through a combination of biological processes and electroless copper deposition, the research team has created tiny wires based on proteins called microtubules, aka MTs.These tubes have an inner diameter of 15 nanometers and an outer diameter of 25 nanometers and can grow to lengths of several micrometers. Red blood cells have a diameter of about 8 micrometers, a distance in which 320 MTs could be lined up side-to-side.
