Imagine taking strands of DNA – the material in our cells that determines how we look and function – and using it to build tiny structures that can deliver drugs to targets within the body or take electronic miniaturization to a whole new level. While it may still sound like science fiction to most of us, researchers have been piecing together and experimenting with DNA structures for decades. And, in recent years, scientists have moved the use of human-made DNA structures closer to a variety of real-world applications.
