We have taken our understanding of DNA to another level, beginning to take advantage of some of DNA’s properties that have served nature so well, but in ways nature itself may have never pursued. Humans can now use DNA as a medium for nano-scale engineering. The resulting newly programmed and built DNA structures can enhance our ability to see and study molecular interactions and the inner-life of cells. As these structures become increasingly complex and versatile, they have the potential to spawn entirely new and revolutionary technologies for biological monitoring, therapeutic delivery, and applications scientists have not even thought of yet. In this episode of Disruptive, Wyss faculty members William Shih, Wesley Wong, and Peng Yin discuss what it is like being on the frontier of science, and the potential applications of their DNA-programming work.
