We explore the use of scaffolded DNA origami nanostructures to load, entrap, and release soluble nanoscale cargo, with potential future applications in drug delivery and molecular signal amplification. Specifically, we design a rectangular box structure that can encapsulate gold nanoparticles and subsequently release them by a two-step process: a) photocleavage, which solubilizes the nanoparticle within the box, and b) introduction of a DNA signal, which opens the box by strand-displacement. We further investigate the use of an existing spherical origami design for similar purposes, and demonstrate opening of the sphere.

DNA Origami Containers

We explore the use of scaffolded DNA origami nanostructures to load, entrap, and release soluble nanoscale cargo, with potential future applications in drug delivery and molecular signal amplification. Specifically, we design a rectangular box structure that can encapsulate gold nanoparticles and subsequently release them by a two-step process: a) photocleavage, which solubilizes the nanoparticle within the box, and b) introduction of a DNA signal, which opens the box by strand-displacement. We further investigate the use of an existing spherical origami design for similar purposes, and demonstrate opening of the sphere.
