EPFL researchers have published a first study on the mechanics of surgical knots, with results that could be used to train surgeons to tie stronger, safer sutures – a skill that usually requires years of practice to master.

To ensure that wounds remain tightly sealed in the abdomen after surgery, researchers at Empa and ETH Zurich have developed a patch with a sensor function. The polymer patch warns before the occurence of dangerous leaks on sutures in the gastrointestinal tract take hold, while closes the areas on its own. A new material now enables a fast, easy and non-invasive leak diagnosis. The team recently published their findings in the journal Advanced Science.

A new AI algorithm developed at EPFL and University Hospital Geneva (HUG) will power an intelligent stethoscope - Pneumoscope - with the potential to improve the management of respiratory disease in low-resource and remote settings.

Pulmonary surfactant is a special fluid released by cells in the lungs. For premature babies and COVID-19 patients in intensive care, it can mean the difference between life and death. An ETH materials scientist hopes to shed some light on this complex substance.

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" with magnetic nanoparticles that detect bacterial pathogens within a short period of time and identify suitable candidates for antibiotic therapies.
