Photonic crystal nanolaser biosensor simplifies DNA detection

A simple method to sense DNA, as well as potential biomarker proteins of cancer or other diseases such as Alzheimer's, may soon be within reach - thanks to the work of a team of Yokohama National University researchers in ...

Novel beams made of twisted atoms

Physicists have, for the first time, now built a theoretical construct of beams made of twisted atoms. These findings by Armen Hayrapetyan and colleagues at Ruprecht-Karls-University Heidelberg in Germany are about to be ...

A path to compact, robust sources for ultrashort laser pulses

Laser researchers in Munich are challenging a basic assumption of engineering: "You can't have it all." They have shown that for certain kinds of laser applications in biomedical imaging, material processing, and communications, ...

Atomic-scale investigations solve key puzzle of LED efficiency

(Phys.org) —From the high-resolution glow of flat screen televisions to light bulbs that last for years, light-emitting diodes (LEDs) continue to transform technology. The celebrated efficiency and versatility of LEDs—and ...

Researchers make optical fibers from common materials

Clemson researchers are taking common materials to uncommon places by transforming easily obtainable and affordable materials into fiber. Their findings are published in Nature Photonics, the world's top journal focused on ...

A magnetic approach to lattices

(Phys.org) -- JQI experimentalists under the direction of Ian Spielman are in the business of using lasers to create novel environments for neutral atoms. For instance, this research group previously enticed electrically ...

How advanced optical tweezers revolutionized cell manipulation

Optical tweezers (OTs), also known as optical traps, are highly focused laser beams that can be used to trap and manipulate microscopic objects with a noncontact force. Employed in a wide range of nano and micro-scale operations, ...

Making lasers more efficient, versatile and compact

Their inner workings reside in the realm of physics, but lasers make everyday life possible. Talking on a cell phone or googling COVID stats while your apples and oranges are scanned at the checkout counter—lasers at every ...
