New imaging method makes tiny robots visible in the body

Important breakthrough in efficiently merging microrobotics and imaging

16-May-2022

Microrobots have the potential to revolutionize medicine. Researchers at the Max Planck ETH Centre for Learning Systems have now developed an imaging technique that for the first time recognises cell-​sized microrobots individually and at high resolution in a living organism. How can a blood clot ...

Bruker and TOFWERK Form Strategic Partnership

On-line chemical ionization techniques for high sensitivity and in situ small molecule detection for stationary and mobile analysis

11-May-2022

Bruker Corporation and TOFWERK AG announced a strategic partnership for high-speed, ultra-sensitive applied and industrial analytical solutions, in conjunction with a Bruker minority investment in TOFWERK. The partnership provides a basis for technology collaborations to advance instrument ...

Revolutionary images of the birth of crystals

A team from the UNIGE has succeeded in visualizing crystal nucleation - the stage that precedes crystallization - that was invisible until now

26-Apr-2022

At the interface between chemistry and physics, the process of crystallization is omnipresent in nature and industry. It is the basis for the formation of snowflakes but also of certain active ingredients used in pharmacology. For the phenomenon to occur for a given substance, it must first go ...

Light amplification accelerates chemical reactions in aerosols

Temporal sequence of photochemical reaction in individual aerosol particles observed with high resolution

21-Apr-2022

Aerosols in the atmosphere react to incident sunlight. This light is amplified in the interior of the aerosol droplets and particles, accelerating reactions. ETH researchers have now been able to demonstrate and quantify this effect and recommend factoring it into future climate models. Liquid ...

Golden wedding for molecules

Opportunities for a "new" chemistry

20-Apr-2022

Chemical syntheses in liquids and gases take place in three-dimensional space. Random collisions between molecules have to result in something new in an extremely short time. But there is another way: on a gold surface under ultrahigh vacuum conditions, molecules lying still next to each other ...

How to find anti-cancer agents

"By combining the three fragments into one molecule, we hoped to enhance the effect, since the new molecule fills the binding pocket better"

14-Apr-2022

Researchers at the Paul Scherrer Institute PSI and the Italian Institute of Technology IIT have developed a novel substance that disables a protein in the cell skeleton, leading to cell death. In this way, substances of this type can prevent, for example, the growth of tumours. To accomplish ...

A look into the magnetic future

Researchers at PSI and ETH Zurich have observed for the first time how tiny magnets in a special layout align themselves solely as a result of temperature changes

06-Apr-2022

This view into processes that take place within so-​called artificial spin ice could play an important role in the development of novel high-​performance computers. When water freezes to form ice, the water molecules, with their hydrogen and oxygen atoms, arrange themselves in a complex ...

A novel painless and reliable allergy test

In vitro mast cells provide unprecedented reliability

23-Mar-2022

Although allergies are widespread, their diagnosis is complex and, depending on the type of allergy, the prospects of success with therapy are not always clear. Skin tests so far have been unpleasant, time-consuming and associated with a certain risk of triggering an allergic overreaction. ...

Novel X-ray lens facilitates glimpse into the nanoworld

Together with spin-off XRnanotech, PSI plans to market the new lens

16-Mar-2022

PSI scientists have developed a ground-breaking achromatic lens for X-rays. This allows the X-ray beams to be accurately focused on a single point even if they have different wavelengths. The new lens will make it much easier to study nanostructures using X-rays, according to a paper just ...

New drug candidates identified in bacteria

Bacteria show great promise as a source of active ingredients

17-Feb-2022

Using computer-​based genome analysis, researchers at ETH Zurich have now discovered a new class of natural products that might one day serve as antibiotics. Animals, plants, fungi and bacteria – each and every organism carries a whole armoury of chemical compounds that enable it to interact with ...
