A new force for optical tweezers

When studying biological cells using optical tweezers, one main issue is the damage caused to the cell by the tool. Giovanni Volpe, University of Gothenburg, has discovered a new type of force that will greatly reduce the ...

How your clothes influence the air you breathe

Dusan Licina, a tenure-track assistant professor at the Smart Living Lab, EPFL Fribourg, has taken a critical look at how much we really know about our exposure to particles and chemicals transported by our clothing. His ...

Popular new construction material helps measure protein particles

Understanding how proteins clump together is essential in modern pharmaceuticals. When these tiny particles aggregate, they can alter the effectiveness of both vaccines and drugs, especially many of the new, popular formulations ...

Individual silver nanoparticles observed in real time

Chemists at Ruhr-Universität Bochum have developed a new method of observing the chemical reactions of individual silver nanoparticles, which only measure a thousandth of the thickness of a human hair, in real time. The ...

Valves for tiny particles

Newly developed nanovalves allow the flow of individual nanoparticles in liquids to be controlled in tiny channels. This is of interest for lab-on-a-chip applications such as in materials science and biomedicine.
