Injectable 'smart sponge' holds promise for controlled drug delivery

Researchers have developed a drug delivery technique for diabetes treatment in which a sponge-like material surrounds an insulin core. The sponge expands and contracts in response to blood sugar levels to release insulin as needed. The technique could also be used for targeted drug delivery to cancer cells.

Nature's nanostructures could inspire new hue-changing materials

Butterfly wings can do remarkable things with light, and humans are still trying to learn from them. Physicists have now uncovered how subtle differences in the tiny crystals of butterfly wings create stunningly varied patterns of color even among closely related species.

Surfing on acoustic waves

Researchers are able to make objects such as particles and liquid droplets fly in mid-air by letting them ride on acoustic waves. For the first time, they have been able to also control the movement of objects, merge droplets, letting them react chemically or biologically and even rotate a toothpick in the air.

Empowering innovation in photonics through collaboration

There is strength in numbers. That is the logic behind an EU-funded project that, by pooling the resources, know-how and technology of multiple organisations across Europe, has helped greatly to advance current research trends in the increasingly important field of photonics.

Using pressure to swell pores, not crush them

High pressure doesn't crush zeolites - it actually makes interior nanopores expand. Researchers show how 'super-hydration' inserts more water molecules into the cavities than can fit under ambient conditions.

New nanoscale imaging method finds application in plasmonics

Researchers have shown how to make nanoscale measurements of critical properties of plasmonic nanomaterials - the specially engineered nanostructures that modify the interaction of light and matter for a variety of applications, including sensors, cloaking (invisibility), photovoltaics and therapeutics.

Carbon nanotube broadband photodetector for polarized light

Using carpets of aligned carbon nanotubes, researchers from Rice University and Sandia National Laboratories have created a solid-state electronic device that is hardwired to detect polarized light across a broad swath of the visible and infrared spectrum.
