Remembering really fast

Colossal magnetoresistance at terahertz frequencies in thin composites boosts novel memory devices operated at extremely high speed.

Using light and gold for targeted, non-invasive drug delivery

The new method uses a unique polymer coating that contains nanoscale gold particles, in addition to the drug itself. The drug only releases when a light shines on the gold particles, causing the polymeric coating to melt.

Concrete infused with wood nanocrystals is stronger

Researchers studying whether concrete is made stronger by infusing it with nanocrystals from wood are moving from the laboratory to the real world with a bridge that will be built in California this spring.

Researchers turn light upside down

A new metasurface for infrared light is based on boron nitride, a graphene-like 2D material, and was selected because of its capability to manipulate infrared light on extremely small length scales, which could be applied for the development of miniaturized chemical sensors or for heat management in nanoscale optoelectronic devices.

Stiffness matters for nanomedicine

Nanomedicine entry into cancer cells can be tuned by modulating the stiffness of the plasma membrane.

Imaging individual flexible DNA 'building blocks' in 3-D

Researchers generate first images of 129 DNA structures.
