Research of Empa scientists on the cover of "Nature": Synthesis of structurally pure carbon nanotubes using molecular seeds

For the first time, researchers at Empa and the Max Planck Institute for Solid State Research have succeeded in "growing" single-wall carbon nanotubes (CNT) with a single predefined structure - and hence with identical electronic properties.

“Active” surfaces control what’s on them: Researchers develop treated surfaces that can actively control how fluids or particles move

Researchers at MIT and in Saudi Arabia have developed a new way of making surfaces that can actively control how fluids or particles move across them. The work might enable new kinds of biomedical or microfluidic devices, or solar panels that could automatically clean themselves of dust and grit.

LEDs made from ‘wonder material’ perovskite: Colourful LEDs made from a material known as perovskite could lead to LED displays which are both cheaper and easier to manufacture in future

A hybrid form of perovskite - the same type of material which has recently been found to make highly efficient solar cells that could one day replace silicon - has been used to make low-cost, easily manufactured LEDs, potentially opening up a wide range of commercial applications in future, such as flexible colour displays.

Light-induced nanocarriers switch on improved gene therapy

Nanocarriers are a useful means of transporting molecules such as genes to specific points in the body, for example to target tumors in cancer therapy. Such nanocarriers must be carefully controlled to avoid the random dissemination of genes in other organs en route to the target cells.

A newly developed, light-induced nanocarrier for targeted gene therapy has been trialled by researchers in Japan. The three-layered micelle safely and effectively delivered gene packages in mice cancer tumor models.
