GENFIT to Acquire Clinical-stage Biopharmaceutical Company Versantis, expanding its Portfolio in Liver Diseases

'Chains' make it easy to tune the color of these polymers

Potential uses include biomedicine, security printing, and solar energy. Around the world, a huge amount of research and development work is underway on carbon-containing, or organic, molecules that emit colored light after appropriate excitation. The display industry and the development of biomedical imaging techniques drives this work. While precise color tuning in organic fluorescent dyes has typically involved mixing different molecules, ETH Zurich researchers have now developed an approach that can generate a broad palette of colors with chemical adjustments within the molecules themselves. Yinyin Bao, a group leader in the group of professor Jean-Christophe Leroux, and his team of scientists turned to fluorescent organic polymers. You can think of these polymers as moving chains of varying lengths.

Chain length determines molecular colour

Date Time Chain length determines molecular colour Researchers at ETH Zurich have developed fluorescent polymers whose colour can be easily tuned. Depending on their length, the polymers emit a different colour. Potential applications include biomedicine, security printing and solar energy. These polymers, seen here under UV light, are composed of the exact same components. The only difference is their chain length.

This research field is driven by the display industry and the development of biomedical imaging techniques. While precise colour tuning in organic fluorescent dyes has so far usually been achieved by mixing different molecules, ETH researchers have now developed an approach that can generate a broad palette of colours by way of chemical adjustmen

How 3D Printing was Used to Create a New Airway Stent

How 3D Printing was Used to Create a New Airway Stent Thought LeadersJean-Christophe Leroux Professor of Drug Formulation and Delivery Professor of Drug Formulation and DeliveryETH Zürich AZoM speaks with Dr. Jean-Christophe Leroux, Professor of Drug Formulation and Delivery at ETH Zürich. Jean-Christophe and his team have developed a new 3D printed airway stent that will allow for the quick and safe treatment of upper airway obstructions.  What benefits will the 3D printed stent make to the treatment of upper airway obstructions? 3D printed stents based on CT scans perfectly fit the anatomical needs of individual patients, enabling them to stay at the place of the insertion. This unprecedented customization could be achieved in a short time and at a reasonable price.
