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...
