Paper-based diagnostic tests are cheap, convenient and biodegradable. However, their use is limited by conventional dyes—which are not bright enough to show trace amounts of analyte, are prone to fading, and can be environmentally ...
Physicists from Immanuel Kant Baltic Federal University have developed and applied a method of identifying microplastic collected in sea waters. The spectroscopy method determines the chemical composition of contaminants ...
The bright colors of some butterflies, beetles or birds are not due to the presence of pigments that selectively absorb light, but due to the so-called structural coloration. Structural coloration occurs on surfaces with ...
As medicine and pharmacology investigate nanoscale processes, it has become increasingly important to identify and characterize different molecules. Raman spectroscopy, a technique that leverages the scattering of laser light ...
Scientists from Tomsk Polytechnic University and the University of Chemistry and Technology (Prague, Czech Republic) have created novel chemical sensors for Raman spectrometers, devices that measure the quantitative and qualitative ...
The higher the concentration of tumor cells in the bloodstream, the greater the risk of metastasis. The number of circulating tumor cells indicates how well a patient is responding to therapy. Fraunhofer researchers have ...
A "chemical imaging" system that uses a special type of laser beam to penetrate deep into tissue might lead to technologies that eliminate the need to draw blood for analyses including drug testing and early detection of ...
Researchers at Georgia Institute of Technology have found a material used for decades to color food items ranging from corn chips to ice creams could potentially have uses far beyond food dyes.
Tiny carbon dots have, for the first time, been applied to intracellular imaging and tracking of drug delivery involving various optical and vibrational spectroscopic-based techniques such as fluorescence, Raman, and hyperspectral ...
According to current estimates, dozens of zettabytes of information will be stored electronically by 2020, which will rely on physical principles that facilitate the use of single atoms or molecules as basic memory cells. ...
