DNA-origami surpasses important thresholds

ScienceDaily.com: Nanotechnology News - Wed, 12/06/2017 - 23:16
It is the double strands of our genes that make them so strong. Using a technique known as DNA origami, biophysicists have been building nanometer-scale objects for several years. Now scientists have not only broken out of the nanometer realm to build larger objects, but have also cut the production costs a thousand-fold. These innovations open a whole new frontier for the technology.

Nanomaterials: How to separate linear and ring-shaped molecules

ScienceDaily.com: Nanotechnology News - Wed, 12/06/2017 - 18:21
What is the difference between linear chains and rings composed of the same material? The molecular building blocks are identical, but from a mathematical point of view the structures have distinct topologies, ring and linear chain. This difference is readily recognizable on a macroscopic scale, but represents a tricky task on the microscopic scale. Physicists have investigated strategies to separate nano- and microparticles of distinct topology.
