New Study Details the Block by Block Assembly of DNA Nanotubes

A team of biomolecular engineers has developed a method for the block by block assembly of DNA nanotubes that controls the positioning of rungs along the backbone of the nanotubes, minimizes the polydispersity in their manufacture, and reduces the building costs.  More...
