A new mass spectrometry technique sorts molecules to capture those of lower abundance. For scientists, a molecule’s weight can help determine its makeup. For measures like this, researchers turn to a ...

Scientists have developed a new technique to screen engineered enzyme reactions, which could lead to faster and more efficient creation of medicines and sustainable chemicals. Enzymes are proteins ...

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a class of synthetic chemicals widely used in industrial processes and consumer products because of their resistance to heat, water and oil.

Mass spectrometry (MS) is an analytical technique used to identify and quantify molecules based on their mass-to-charge ratio (m/z). It provides valuable information about the chemical composition, ...

A new data-driven technique, called fingerprint mass spectrometry, provides a method for measuring the mass of individual proteins using nanoscale devices. Caltech scientists have developed a method ...

Mass spectrometry has become the cornerstone for the accurate measurement of steroid hormones across clinical, preclinical and research settings. The integration of chromatographic separation with ...

Automatic acquisition and processing of mass-spectral data / R. Venkataraghavan -- Photographic techniques in organic high-resolution mass spectrometry / Dominic M. Desiderio, Jr. -- The electrical ...

For biologists, seeing is believing. But sometimes biologists have a hard time seeing. One particularly vexing challenge is seeing all the molecules in an intact tissue sample, down to the level of ...

In Star Trek, Mr. Spock’s hand-held tricorder can instantly tell what something is made of. We don’t have tricorders yet, but we’re getting close. Portable devices just a little too big to hold in one ...
