Nanosafety research without animal experiments

Risk analyses for nanoparticles

23-Jun-2020

In order to reduce the number of animal experiments in research, alternative methods are being sought. This is a particular challenge if the safety of substances that have hardly been studied is to be ensured, for instance, the completely new class of nanomaterials. To accomplish just that, Empa ...

A new biosensor for the COVID-19 virus

Detection in the environment

23-Apr-2020

A team of researchers from Empa, ETH Zurich and Zurich University Hospital has succeeded in developing a novel sensor for detecting the new coronavirus. In future it could be used to measure the concentration of the virus in the environment - for example in places where there are many people or ...

Quantum cascade laser measures ethanol

Precision work for large molecules

01-Apr-2019

Quantum cascade lasers are able to measure the smallest molecules with high precision. But the technology has failed to measure larger gas molecules - until now! Empa researchers have succeeded in quantifying ethanol, an important organic molecule, with the aid of such a laser. In collaboration ...
