Prior research has shown that DNA strands can be programmable, mimicking circuits and even solving simple math problems. The team in Israel has now extended that work to show that such programmability can be used inside of a living organism to perform work, such as destroying cancer cells.
DNA strands can be programmed because of their natural tendency to react to different proteins. In this new effort, the team unwound DNA strands and then tied them together in an origami type box structure. The box was then “filled” with a single chemical molecule. Next, other such objects were created for the purpose of interacting with both the box structure and certain proteins found inside of the cockroach. The whole point was to create multiple scenarios in which the box would open automatically upon colliding with certain proteins. Adding multiple nanostructures allows for increasing the number of possibilities.
