Read moreGold nanoparticles help earlier diagnosis of liver cancer
A research team led by Brown University reports some promising results for earlier diagnosis of hepatocellular carcinoma, the most common cancer to strike the liver. More than 500,000 people worldwide, concentrated in sub-Saharan Africa and Southeast Asia, are diagnosed with it yearly. Most of those afflicted die within six months.

Read moreNanopores follow nature's design in tracking proteins
Dutch and Swiss researchers have developed a biomimetic nanopore that offers a sophisticated test and measurement platform for the way proteins enter the nucleus of a cell. This study provides evidence of how a biomimetic nuclear pore can be created to monitor how single proteins move across the pore.

Read moreVersatile membrane makes large-scale energy-efficient separation possible
Hessel Castricum from the University of Amsterdam has developed a versatile membrane that is capable of separating gas and liquid mixtures in an energy-efficient manner. The new membrane can probably be employed under industrial conditions on a large scale in the future. This has not been possible until now, because virtually all membranes developed so far are insufficiently stable.
