Nanotechnology researchers are continually on the lookout for new building blocks to push innovation and discovery to scales much smaller than the tiniest speck of dust.  At present DNA nanotechnology researchers are basically limited by what they can buy off the shelf.
In the Biodesign Institute at Arizona State University, researchers led by John Chaput, are building synthetic molecules that assemble like DNA, but have additional properties not found in natural DNA.  It’s called GNA. In the case of GNA, the sugar is the only difference with DNA. The five carbon sugar commonly found in DNA, called …read more
