Raman spectroscopy is an analytical technique which can be used to identify the pigments used in a painting. A low powered laser is directed onto the surface of an object or painting and the light ...

Microplastics and much smaller nanoplastics enter the human body in various ways, for example through food or the air we ...

Schematic representation of Raman spectroscopy. After the sample (molecule) is exposed to an intense beam of monochromatic light in the frequency range of visible, near-infrared or near-ultraviolet ...

laser induced fluorescence line narrowing, time resolved site selection spectroscopy, and Raman spectroscopy at temperatures ranging from liquid helium temperature (4 K) to 500 K and excitation with ...

In collaboration with the company BRAVE Analytics, researchers at TU Graz have developed a method to detect nanoplastics in ...

"Our method for detecting micro- and nanoplastics can be applied to clear body fluids such as urine, tear fluid or blood ...

Raman spectroscopy is a widely used measurement technique for this purpose. When a laser beam is projected onto molecules, the light interacts with the vibrations and rotations of molecular bonds ...

Over the last decade Raman spectroscopy has become established as a physicochemical technique for the rapid identification of microbes. This powerful analytical method generates a spectroscopic ...

When laser spectroscopy is combined with microscopy, spatial variations of the chemical compositions of both organic and inorganic samples can be precisely determined. One of the spectroscopic ...
