Self-assembling DNA used in nanoscale delivery system

A team at Harvard's Wyss Institute for Biologically Inspired Engineering, Harvard Medical School, and Dana-Farber Cancer Institute has created nanodevices made of DNA that self-assemble and can be programmed to move and change shape on demand--a discovery that could lead to nanoscale drug-delivery systems....

DNA nanobots can assemble particles, follow instructions

Two independent teams of research pioneers report today that they were each able to make a crude DNA nanobot, creating microscopic workers that could be chemically directed to coordinate efforts or programmed to execute the simple orders of their scientific masters. At NYU investigators used DNA molecules to make tiny devices that assembled gold particles while another group at Columbia made DNA robots that could be directed to execute a simple set of moves. The...
