A gap-controlled infrared technique makes it possible to study molecular interfaces with high sensitivity using affordable, widely available lab equipment. These molecular interfaces are everywhere—on ...

Researchers at St. Petersburg University have developed an efficient way to detect a crucial immunity biomarker—neopterin—in the blood using nanotechnology and a laser. Neopterin is a nucleotide whose ...

Different atoms and ions possess characteristic energy levels. Like a fingerprint, they are unique for each species. Among them, the atomic ion 173 Yb + has attracted growing interest because of its ...

While many people often use spectroscopy and spectrometry interchangeably, there are some subtle differences in their exact meanings and the associated experimental techniques they are used to ...

Near-infrared spectroscopy, known as NIR spectroscopy or NIRS, is a long-established analytical technique. For over 30 years, it has proven to be a fast and reliable method for measuring chemical and ...

Elemental spectroscopy is a method employed to examine in-service fluid samples such as engine oil or hydraulic fluid, to determine the presence and quantity of different substances. This approach ...

Accurately and rapidly quantifying protein content is essential for modern biology, biochemistry, and biophysics laboratories worldwide. Researchers are focused on determining total protein content, ...

Dynamics Author: Howard Goldner During the past few decades, fluorescence spectroscopy has developed into an integral technique in many scientific disciplines. In the life sciences, it is implemented ...

Researchers have shown how spectroscopic measurements can be made much faster. By correlating polarization to the color of a pulsed laser, the team can track changes in the spectrum of the light by ...
