The indestructible light beam

Researchers create special light waves that can penetrate even opaque materials as if the material was not even there

14-Apr-2021

Why is sugar not transparent? Because light that penetrates a piece of sugar is scattered, altered and deflected in a highly complicated way. However, as a research team from TU Wien (Vienna) and Utrecht University (Netherlands) has now been able to show, there is a class of very special light ...

Beware doping athletes! This sensor may be your downfall

02-Aug-2017

Scientists searching for traces of drugs, bomb-making components and other chemicals often shine light on the materials they're analyzing. This approach is known as spectroscopy, and it involves studying how light interacts with trace amounts of matter. One of the more effective types of ...

In Flow State

03-Mar-2017

Ever wonder why you have to shake your bottle of ketchup or mustard before pouring? Or why, to get out of quicksand, you must move slowly? Or why you can run on the surface of a suspension of cornstarch in water, but you’d sink if you tried to walk on it? The common feature of all these ...

New technique to sharpen microscope images

15-Apr-2014

The complexity of biology can befuddle even the most sophisticated light microscopes. Biological samples bend light in unpredictable ways, returning difficult-to-interpret information to the microscope and distorting the resulting image. New imaging technology developed at the Howard Hughes ...

Vibrational molecular pathology

11-Dec-2013

IR and Raman spectral imaging can distinguish between tissue types, disease types and stages, and even identify the primary tumors from spectral patterns observed in metastatic cells. Furthermore, these techniques can be used in the detection of circulating tumor cells. Spectral histopathology ...

A new Concept in Microscopy: Self-reconstructing Laser Beams

Researchers at the University of Freiburg are developing a microscope with illuminating beams that actively refocus in a light-scattering medium

14-Oct-2010

It’s a familiar situation for all car drivers. In the autumn, when the roads are foggy, visibility drops below 50 metres. The light of the car’s headlights are scattered by the drops of fog, meaning we can’t see objects further away because the light can’t reach them. This everyday example ...

Tiny whispering gallery

A sensor can detect a single nanoparticle and take its measurement

23-Dec-2009

Nanotechnology has already made it to the shelves of your local pharmacy and grocery: nanoparticles are found in anti-odor socks, makeup, makeup remover, sunscreen, anti-graffiti paint, home pregnancy tests, plastic beer bottles, anti-bacterial doorknobs, plastic bags for storing vegetables, and ...

Colon cancer screening technique shows continued promise in new study

11-Jun-2009

Recent clinical trials show that a new colon cancer screening technique created by Northwestern University researchers has a high enough sensitivity that it could potentially be as or more successful than a colonoscopy in screening for colon cancer. The technique uses optical technology, called ...

National Physical Laboratory to Evaluate NanoSight

17-Mar-2009

The UK’s national metrology institute, the National Physical Laboratory (NPL), is commencing a one-year evaluation program of NanoSight’s nanoparticle characterization technology, Nanoparticle Tracking Analysis (NTA). The program takes the form of a Joint Industry Project, funded in part by ...
