Carbon Nanotube-based Gas Sensors

Carbon nanotube-based gas sensors promise very low limit of detection and operating power. We employ carbon nanotube field-effect transistors in toxic gas (e.g. NO2) sensing applications, by analyzing the changes in electrical transport characteristics of carbon nanotubes (CNTs) upon gas exposure.

Finding and blocking infection routes in hospitals

Digital epidemiologist Onicio Batista Leal Neto standing in front of an ETH building with his arms folded.

During the COVID-19 pandemic, hospitals often became hubs of infection. Researchers from ETH Zurich, EPFL and the ISI Foundation are developing a wearable tracking system for healthcare facilities that can identify the risks of infections. Initial tests in Switzerland and Africa show its potential.

Acids help against airborne viruses

Man coughing, aerosol particles floating in the air in front of him

A new study by various Swiss universities shows that aerosols in indoor air can vary in acidity. This acidity determines how long viruses remain infectious in the air – with profound implications for virus transmission and strategies to contain it.

Preparing for future coronavirus variants using artificial intelligence

Illustration of the detail view of coronaviruses.

Researchers at ETH Zurich have developed a method to explore the possibilities of how the pandemic virus could evolve. Thanks to their work, it may be possible to develop antibody therapies and vaccines that are more likely to be effective also against future viral variants.
