• The chips were created using a technique developed several years ago to anchor DNA to silicon. The system allowed the researchers to create a simple network of interacting genes.
  • Scientists can already easily synthesize proteins from DNA in a test tube, but those reactions eventually fizzle out as proteins accumulate and synthesis slows. This new chip overcomes that problem by flushing away waste products and controls how fast the proteins manufactured in it are diffused to other areas of the chip, influencing other reactions.
  • The chip may eventually lead to applications in diagnostics, environmental sensing, or drug screening, with the twist that it could keep reactions going for a longer time. Scientists say the chips could be used to test new genetic constructs before they’re put into actual cells, like bacteria.
