- Polymer cables for MRI applications
Magnetic resonance imaging, MRI for short, is a powerful imaging technique in medicine. It can be used to produce high-resolution images of tissues and organs that reveal even the tiniest injuries,...
- PFAS in ski wax: chemicals on the ski trail
When the forever chemicals known as PFAS enter the environment, they remain there for generations and can harm humans and nature. Despite increasing bans, many PFAS are still in circulation - inclu... - Green electronics thanks to biodegradable circuit boards
Modern printed circuit boards are made from petroleum-based materials and are difficult to recycle. Empa researchers have developed a biodegradable version - an important step toward sustainable el... - Activated by NIR light: new germicidal surface coating
Light on - bacteria dead. Disinfecting surfaces could be as simple as that. To turn this idea into a weapon against antibiotic-resistant germs, Empa researchers are developing a coating whose germi... - 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... - Muscles from the 3D printer
Empa researchers are working on artificial muscles that can keep up with the real thing. They have now developed a method of producing the soft and elastic, yet powerful structures using 3D printin... - How dangerous are nanoplastics for babies in the womb?
Allergies and asthma are widespread diseases that could arise during embryonal development in the womb. A team led by Empa researcher Tina Bürki is investigating the possible causes of this. Th... - 3D-printed, biodegradable fungal battery
A battery that needs feeding instead of charging? This is exactly what Empa researchers have achieved with their 3D-printed, biodegradable fungal battery. The living battery could supply power to s...
- Environmental treaty shows effect: Decline in harmful ozone-depleting greenhouse gases
A new study by an international team of researchers, published today in Nature Climate Change, has revealed significant progress in the drive to reduce atmospheric levels of chemicals that destroy ... - Nanoparticles: Risk for babies in the womb
Little is yet known about the health effects of nanoparticles on pregnancy. An interdisciplinary team led by Empa researchers is currently analyzing the risks for babies in the womb. Using a la... - Eco-friendly textiles without PFAS
Rain jackets, swimming trunks or upholstery fabrics: Textiles with water-repellent properties require chemical impregnation. Although fluorine-containing PFAS chemicals are effective, they are also... - Biodegradable aerogel from a 3D printer
Ultra-light, thermally insulating and biodegradable: Cellulose-based aerogels are versatile. Empa researchers have succeeded in 3D printing the natural material into complex shapes that could one d... - Release of so-called nanoparticulate oligomers from polyester textiles
Textiles made of synthetic fibers release micro- and nanoplastics during washing. Empa researchers have now been able to show: Some of the supposed nanoplastics do not actually consist of plastic p... - 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 ...
- Good bacteria for bad wounds
Empa researchers are developing a dressing containing probiotic lactobacilli. These are intended to heal chronically infected wounds by destroying persistent biofilms, the scientists report in a st... - New epoxy resin: recyclable, repairable and flame retardant
Epoxy resins are tough and versatile polymers. In combination with glass or carbon fibers, they are used, for example, to manufacture components for aircraft, cars, trains, ships and wind turbines.... - A model that can be used to calculate the concentration of microplastics in lakes and rivers
Every year, 14,000 tons of plastic end up in Swiss soils and waters, in part in the form of microplastics: Particles in the micro to millimeter range. Microplastics comes from many sources, such as... - 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... - Graphene dust not harmful, study finds
Graphene-based particles released from polymer composites after abrasion induce negligible health effects. Under the leadership of Empa, an international research team of the Graphene Flagship proj...
- Where viruses reach their limits - developing surfaces with antiviral properties
Using a new analytical method, Empa researchers have tracked viruses as they pass through face masks and compared their failure on the filter layers of different types of masks. The new method shou... - A chip to replace animal testing
Empa researchers are developing a medical chip in collaboration with the ETH Zurich and the Cantonal Hospital of St.Gallen that will allow statements to be made about the effect of substances on ba... - Golden wedding for molecules
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 anothe... - Nanoplastic in the environment - plastic snowfall in the Alps
In a large-scale fundraising campaign, popular YouTubers like Mister Beast and Mark Rober are currently trying to rid the oceans of almost 14,000 tonnes of plastic waste. That's about 0.15 per cent... - Natural coatings as an alternative to petroleum-based packaging
Empa and Lidl Switzerland have jointly developed a cellulose protective coating for fruit and vegetables. The novel coating is made from so-called pomace - squeezed fruit and vegetable peels. The i...
