- Iron supplementation based on nanofibers from oat proteins and iron nanoparticles
Researchers at ETH Zurich have developed and tested a new compound to combat iron deficiency. The body can absorb this iron virtually twice as fast as iron in current supplements. It could effectiv... - The world's chemical pollution: Current state
The rapid production and distribution of chemicals in the environment means that regulatory risk assessment can no longer keep pace with their ever-increasing number. This is the conclusion reached... - New method makes differences between left- and right-handed structures visible in color
Why do spearmint and caraway seeds smell so differently, although their main scent molecules are almost identical? Why can a medicine save lives, while its mirror image is ineffective or even harmf... - Mapping the metabolism of blood stem cells
Researchers from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg and ETH Zürich have created the first integrated map detailing the metabolic and molecular changes in human bl... - A building material that lives and stores carbon
Researchers are developing a living material that actively extracts carbon dioxide from the atmosphere. Photosynthetic cyanobacteria grow inside it, forming biomass and solid minerals and thus bind... - Ultra-thin lenses that make infrared light visible
Lenses are the most widely used optical devices. Camera lens or objectives, for example, produce a sharp photo or video by directing light at a focal point. The speed of evolution made in the field... - Dangerous increase in antimicrobial resistance - Sensors against superbugs
Antibiotic-resistant bacteria can cause life-threatening infections that are almost impossible to treat with existing medication. As a result, common illnesses such as urinary tract infections or s... - Measure minute quantities of oxygen selectively, efficiently and reliably in gas mixtures
Oxygen is essential for life and a reactive player in many chemical processes. Accordingly, methods that accurately measure oxygen are relevant for numerous industrial and medical applications: ... - Interpreting traces of arsenic in rain
On the Pic du Midi in the Pyrenees, ETH Zurich researchers have analysed particulate matter, clouds and rainwater for traces of arsenic. Using newly developed measurement methods, they have elucida...
- New method in the fight against forever chemicals
Researchers at ETH Zurich have developed a new way to break down a dangerous subgroup of PFAS known as PFOS. With the help of nanoparticles and ultrasound, piezocatalysis could offer an effective a... - Chemical plastics recycling is ready to go
Scientists around the world can now go full throttle in their research into chemical plastics recycling. Researchers at ETH Zurich have laid important foundations for this by showing that it's all ... - New X-ray world record: Looking inside a microchip with 4 nanometre precision
In a collaboration with EPFL Lausanne, ETH Zurich and the University of Southern California researchers at the Paul Scherrer Institute PSI have used X-rays to look inside a microchip with higher pr... - Turnimng bacteria into cellulose-producing mini-factories
ETH researchers have modified certain bacteria with UV light so that they produce more cellulose. The basis for this is a new approach with which the researchers generate thousands of bacterial var... - Mining rare earth metals from electronic waste
ETH researchers are developing a process inspired by nature that efficiently recovers europium from old fluorescent lamps. The approach could lead to the long-awaited recycling of rare earth metals... - Cocoa fruit chocolate - more sustainable and healthier than conventional chocolate
For many people, chocolate is a sweet delight: its main components are cocoa mass and cocoa butter, which are extracted from the cocoa fruit. What is less known, however, is that the cocoa fruit co... - New gel breaks down alcohol in the body
Researchers at ETH Zurich have developed a protein-based gel that breaks down alcohol in the gastrointestinal tract without harming the body. In the future, people who take the gel could reduce the... - Bacteria for climate-neutral chemicals of the future
Researchers at ETH Zurich have engineered bacteria in the laboratory to efficiently use methanol. The metabolism of these bacteria can now be tapped into to produce valuable products currently made... - Gold recovery from e-waste by food-waste Amyloid aerogels
Transforming base materials into gold was one of the elusive goals of the alchemists of yore. Now Professor Raffaele Mezzenga from the Department of Health Sciences and Technology at ETH Zurich has... - How to make bright quantum dots even brighter
Researchers at Empa and ETH Zurich have developed new methods for making perovskite quantum dots faster and more efficient light emitters, thereby significantly improving their brightness. This is ... - Capturing greenhouse gases with the help of light
Researchers at ETH Zurich are developing a new method to remove CO2 from the atmosphere. It involves molecules that become acidic when exposed to light. Their new process requires much less energy ...
- Generating clean electricity with chicken feathers
The food industry generates enormous amounts of waste and by-products, including from poultry production. Each year, some 40 million tonnes of chicken feathers are incinerated. This not only releas... - Detection of bacteria and viruses with fluorescent nanotubes
An interdisciplinary research team from Bochum, Duisburg and Zurich has developed a new approach to construct modular optical sensors which are capable of detecting viruses and bacteria. For this p... - Why urea may have been the gateway to life
Urea reacts extremely quickly under the conditions that existed when our planet was newly formed. This new insight furthers our understanding of how life on Earth might have begun. Researchers ... - Antibiotics crisis: nanoparticles as therapy guide - rapid test for sepsis
In the case of blood poisoning, the bacteria in the blood must be identified as fast as possible so that a life-saving therapy can be started. Empa researchers have now developed "sepsis sensors" w...
- Producing fertiliser without carbon emissions
Researchers at ETH Zurich and the Carnegie Institution for Science have shown how nitrogen fertiliser could be produced more sustainably. This is necessary not only to protect the climate, but also...
