Smaller, Smarter Light-Sensing Microchips to Power Electronics

Scientists have developed a way to create super-charged, super-small light sensor microchips. The silicon chips are delivered to the lab, at which the team processes them further with electron beam lithography. Carbon nanotubes are deposited on the chips, which are coded with nanoparticles. The nanotubes are then sensitized to different colors of light. Learn what role DNA plays in the process.
