Graphene chemical sensor could unlock anesthesia's secrets

Researchers created an artificial chemical sensor based on one of the human body's most important receptors - one that is critical in the action of painkillers and anesthetics. In these devices, the receptors' activation produces an electrical response rather than a biochemical one, allowing that response to be read out by a computer.

Nanocellulose sponges to combat oil pollution

A new, absorbable material from Empa wood research could be of assistance in future oil spill accidents: a chemically modified nanocellulose sponge. The light material absorbs the oil spill, remains floating on the surface and can then be recovered.

Genetic approach helps design broadband metamaterial

A specially formed material that can provide custom broadband absorption in the infrared can be identified and manufactured using 'genetic algorithms', according to engineers, who say these metamaterials can shield objects from view by infrared sensors, protect instruments and be manufactured to cover a variety of wavelengths.

Nanoscopic technique tracks proteins in single HIV particle

Researchers have developed a new technique to examine how proteins interact with each other at the level of a single HIV viral particle. The technique allows scientists to study the life-threatening virus in detail and makes screening potential anti-HIV drugs quicker and more efficient. The technique can also be used to study other diseases.
