Single-celled architects inspire new nanotechnology

Diatoms are tiny, unicellular creatures, inhabiting oceans, lakes, rivers, and soils. Through their respiration, they produce close to a quarter of the oxygen on earth, nearly as much as the world's tropical forests. In addition ...

DNA origami more resilient than previously understood

The DNA origami technique is a widely used method for making complex, yet well-defined nanostructures, with applications in biophysics, molecular biology, as well as drug and enzyme delivery. A major challenge, however, has ...

Earwigs and the art of origami

ETH Zurich researchers have developed multifunctional origami structures, which they then fabricated into 4-D printed objects. The design principle mimics the structure of an earwig's wing.

Building miniature optical antennas using DNA as a guide

An international research collaborative has reported a new, highly parallel technique to fabricate precise metallic nanostructures with designed plasmonic properties by means of self-assembled DNA origami shapes. The so-called ...

Scientists lay out why some origami won't fold under pressure

Scientists and engineers are fascinated by self-folding structures. Imagine the possibilities: heart stents that unfold in the right location or pop-up tents that assemble at the press of a button, as well as nanoscale versions ...

New configuration of DNA discovered

Pulling sufficiently hard on DNA may cause it to unfold, doubling its total length. This new state of DNA is announced today by researchers from Eindhoven University of Technology (TU/e) and the Vrije Universiteit Amsterdam ...
