DNA is known to us as the molecule of life, the blueprint that defines who we are. But the very properties that make DNA such a reliable molecule for information storage also make it one of the most remarkable building materials. Our group aims to take DNA out of its biological context, and to use this molecule to build two- and three-dimensional structures. These DNA materials feature precise positioning of their components on the nanometer scale, and they can act as molecular machines that respond to specific external stimuli.
For example, we have constructed DNA cages that encapsulate drug cargo and then release it rapidly and completely when a cancer-specific molecule is present. We are optimizing these DNA cages as a new class of delivery vehicles that selectively release therapeutics into diseased cells, as probes that can report on events happening within cells, and as nucleic acid therapeutic routes.
Our construction methods are distinct, in that they combine the use of synthetic molecules with natural DNA base-pairing. This approach has led to DNA-minimal routes to materials that are practical and scalable. We have organized transition metals, gold nanoparticles, lipids and synthetic polymers on DNA scaffolds, and are developing these systems towards applications as biological sensors, enzyme mimics, light-harvesting systems, plasmonic tools and nanoelectronic components.
