The intracellular environment "is chaotic and violent, like being in a hurricane," said researcher William Shih. "We think this is a big advance." Photo courtesy Dana-Farber Cance Institute |
Scientists create custom three-dimensional structures with ‘DNA origami’By combining the art of origami with nanotechnology, Dana-Farber Cancer Institute researchers have folded sheets of DNA into multilayered objects with dimensions thousands of times smaller than the thickness of a human hair. These tiny structures could be forerunners of custom-made biomedical nanodevices such as "smart" delivery vehicles that would sneak drugs into patients' cells, where they would dump their cargo on a specific molecular target. |
