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.
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.
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.
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.
A unique collaboration between chemists and mathematicians at Eindhoven University of Technology has led to a new imaging technique that enables the study of molecular self-assembly with an unprecedented level of detail.
