Theorists find generalized connection between spin currents, magnetic torques, and mechanical torques

Paul Haney and Mark Stiles of the CNST have developed a theory of current-induced torques that generalizes the relationship between spin transfer torques, total angular momentum current, and mechanical torques, and is applicable to a much wider range of materials than previous theories.

Photolithography using a two-photon laser makes it possible to produce precise microstructured scaffolds for tissue engineering

The repair of organs, such as human kidney and liver, hinges on the development of three-dimensional (3D) tissue scaffolds with well-defined microstructures. Andrew Wan, Jackie Y. Ying and co-workers at the A*STAR Institute of Bioengineering and Nanotechnology have now developed a photolithography method that can be used to fabricate microstructured 3D tissue materials with high precision.

Silicon nanowire device can detect dengue viruses in less than 30 minutes

Scientists have developed a silicon nanowire-based biosensor that can detect the 'reverse transcription polymerase chain reaction' product of dengue type 2 (DEN-2) viruses in less than 30 minutes. The device utilizes silicon nanowires affixed with peptide nucleic acid (PNA) probes to recognize complementary DNA fragments of DEN-2.

Nanotechnology engineer's novel liquid provides a solid fix for broken bones

Here's the vision: an elderly woman comes into the emergency room after a fall. She has broken her hip. The orthopaedic surgeon doesn't come with metal plates or screws or shiny titanium ball joints. Instead, she pulls out a syringe filled with a new kind of liquid that will solidify in seconds and injects into the break. Over time, new bone tissue will take its place, encouraged by natural growth factors embedded in the synthetic molecules of the material.
