Duke engineers build DNA 'nanotowers'

Duke engineers using an enzyme called TdTase can vertically extend short DNA chains attached to nanometer-sized gold plates. This advance adds new capability to the field of bio-nanomanufacturing. "The process works like stacking Legos to make a tower and is an important step toward creating functional nanostructures out of biological materials," said Ashutosh Chilkoti, associate professor of biomedical engineering at Duke's Pratt School of Engineering. more @
