Researchers create a huge variety of programmed three-dimensional shapes out of single strands of synthetic DNA, a process known as DNA origami. These nanoparticles may ultimately be deployed as structural scaffolds to deliver vaccines, drugs, or even gene-editing tools such as CRISPR-Cas9 to specific parts of the body, he says.
