You must have noticed the sudden change in pitch of a siren on a police car zooming past. That’s the Doppler effect. Scientists at Purdue University have now used the Doppler effect to look inside living cells in a novel approach to detect pathogens and treat infections.
In this unique method, Doppler is used to quickly track metabolic activity in cells and can be used to detect pathogenic microbes in food, water, and other environments and identify treatments for antibiotic-resistant bacteria.
Scientists Use Weather Radar Tech to Watch Storms of Microbes Brew Inside Cells
28 FEBRUARY 2021
Scientists are using a radar-like weather system to watch as a storm of pathogens brew inside living tissue.
The strategy is entirely novel, according to the authors, and relies on a technique very similar to Doppler radars, which can detect the motion of precipitation and predict upcoming weather patterns.
Doppler ultrasounds, which use sound waves to create images of blood flow, are already used in the medical sphere, but this new technique can allow scientists to peek inside individual cells to see how they respond to pathogens like salmonella and
Doppler radar improves lives by peeking inside air masses to predict the weather. A Purdue University team is using similar technology to look inside living cells, introducing a method to detect pathogens and treat infections in ways that scientists never have before.
