Fluorescence and Raman spectroscopy have become indispensable tools for non-invasively monitoring biological processes. Both methods rely on a stimulus light source, usually a laser, to excite either ...

A recent study introduces mass spectrometry imaging (MSI ... Traditional imaging techniques, such as fluorescence and electron microscopy, struggle to specifically identify microplastics without ...

However, current methods do not yet allow for the complete characterization of proteomes. “We’re now talking about mass spectrometry at the single molecule level; the ability to look at entire ...

Attribution (BY): Credit must be given to the creator. Native top-down mass spectrometry is a powerful approach for characterizing proteoforms and has recently been applied to provide similarly ...

Red laser light is coupled into a spectrometer chip with an optical fiber from the left. The light travels along the chip until it is scattered out the top in a waveguide section on the right.

They work by breaking down light waves into their different colors—or spectra—to provide information ... this paper that the tool is capable of fluorescence detection, which is a noninvasive ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

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 ...
