Researchers at EPFL and Vrije Universiteit Brussel have developed a novel and highly efficient method for rapid antibiotic susceptibility testing using optical microscopy. The technique, called ...

If the bacteria with which someone is infected are antibiotic-resistant, physicians need to know so as soon as possible, so they can take the appropriate action. A simple new system could help, by ...

“We have developed a technique in our laboratories that allows us to obtain an antibiogram within 2-4 hours – instead of the current 24 hours for the most common germs and one month for tuberculosis,” ...

German researchers have used lasers to make a tiny little tractor beam suitable for manipulating and imaging single living cells. Share on Facebook (opens in a new window) Share on X (opens in a new ...

Assessing how resistant different bacteria are to antibiotic treatments is a vital current challenge in public healthcare, as instances of antibiotic resistance continue to grow. Optical techniques ...

Microscopes have long been scientists’ eyes into the unseen, revealing everything from bustling cells to viruses and nanoscale structures. However, even the most powerful optical microscopes have been ...

Microscopes are an important tool in biomedical research as it allows for detailed observation and imaging of tissues. Since biological materials are opaque by their nature, severe light scattering ...

Imagine you’re a PhD student with a fluorescent microscope and a sample of live bacteria. What’s the best way use these resources to obtain detailed observations of bacterial division from the sample?

When Art Ashkin, Steve Chu, and their colleagues at Bell Labs in Holmdel, NJ, first invented optical tweezers, they spent their days pushing around tiny, glass spheres. But it wasn't long after their ...

Sneezes, rain clouds, and ink jet printers: They all produce or contain liquid droplets so tiny it would take several billion of them to fill a liter bottle. Measuring the volume, motion and contents ...
