A team of scientists from Osaka City University (Japan) presented a reliable and accurate thermometer based on
The researchers noted that the optical microscopeIs one of the main analytical tools in biology that uses visible light to see small structures with the naked eye. In a modern laboratory, a fluorescence microscope is more often used - an improved version of an optical microscope with fluorescent biomarkers. Recent advances in fluorescence microscopy have allowed real-time imaging of structural details, and thus different physiological parameters in these different structures.
Using a similar method, scientists have equippedsurface of nanodiamonds with polymer structures and injected them into C. elegans nematode worms. So they wanted to find out the average temperature of the worms. Once inside, the nanodiamonds moved quickly, but the team's new quantum thermometry algorithm successfully tracked them and measured their temperature stably.
A map of anomalous temperatures across the planet has appeared
The worms were induced to fever by stimulating their mitochondria with pharmacological treatments. A quantum thermometer recorded an increase in temperature.
“It was fascinating to see how quantumtechnologies work in animals, we could not imagine that we could fix the minimum temperature change in worms of less than 1 mm. Our results are an important milestone that will determine the future direction of quantum sensing, ”the scientists noted.
