Nanoparticles, engineered materials about a billionth of a meter in size, are around us every day. Although they are tiny, they can benefit human health, as in some innovative early cancer treatments, but they can also interfere ...
(Phys.org) —The development of a 'nanobarrel' that traps and concentrates light onto single molecules could be used as a low-cost and reliable diagnostic test.
In order to investigate inflammation, tumors or stem cells, medical practitioners analyze living cells. Non-invasive optical procedures such as Raman spectroscopy accelerate this procedure. Researchers have now developed ...
A new test for meningitis – which could help deliver faster and more effective treatments for patients – has been developed through University of Strathclyde-led research.
Applications in imaging and sensing typically involve the emission of light at a different wavelength than the excitation, or "secondary light emission." The interpretation of resonant secondary light emission in terms of ...

Medical diagnostics is searching for substances capable of documenting early on whether a serious disease is developing or what its course will be. In many cases, the treacherous molecules are present only in trace amounts ...
Physicists have developed a "planet-satellite model" to precisely connect and arrange nanoparticles in three-dimensional structures. Inspired by the photosystems of plants and algae, these artificial nanoassemblies might ...
Richard Martel and his research team at the Department of Chemistry of the Université de Montréal have discovered a method to improve detection of the infinitely small. Their discovery is presented in the November 24 online ...
A team of scientists around Prof. Theodor W. Hänsch and Dr. Nathalie Picqué at the Laser Spectroscopy Division of the Max Planck Institute of Quantum Optics (Garching), in a collaboration with the Ludwig-Maximilians-Universität ...
The University of Montreal chemist Richard Martel explores a vast world on a tiny scale. "There are more H2O molecules in a sip of water [≈1024] than there are seconds since the Big Bang [≈1018]," he says to illustrate the ...
