New sensor for SARS-CoV-2 and other viruses

Better and faster virus detection with single-nanopore membranes

12-Oct-2021

Easy and fast detection of viruses are crucial in a pandemic. Based on single-nanopore membranes of GSI, an international interdisciplinary team of researchers developed a test method that detects SARS-CoV-2 in saliva, without sample pretreatment, with the same sensitivity as a qPCR test, and in ...

Artificial opals measure temperature and time

Researchers discover novel sensors

30-Sep-2021

Due to their iridescent colors, opals have been considered particularly precious gemstones since antiquity. The way these stones shimmer is caused by their nanostructures. A research group led by Prof. Dr. Markus Retsch at the University of Bayreuth has produced colloidal crystals mimicking such ...

Antibiotic levels measurable in breath for first time

Researchers are testing a biosensor for personalized dosing of medications

23-Sep-2021

A team of engineers and biotechnologists at the University of Freiburg has for the first time shown in mammals that the concentration of antibiotics in the body can be determined using breath samples. The breath measurements also corresponded to the antibiotic concentrations in the blood. The ...

Engineers develop prototype of electronic nose

A nose by any other name is a gas sensor

06-Sep-2021

There’s nothing like the smell of freshly brewed coffee in the morning. But how does one measure that smell? There’s no energy in a smell to help estimate how potent the coffee might be. Instead, it’s the gases emitted from brewed coffee that contribute to the invigorating scent. The human nose ...
