Finding Chemicals inside a Cell

Chemical and topographical single-cell imaging at nanoscale resolution by near-field desorption mass spectrometry

08-Feb-2019

How are chemicals distributed in a cell? Chinese scientists have developed a combined mass spectrometry and biological imaging device that enables direct, label-free detection, and high-resolution mapping of chemicals inside a biological cell. As demonstrated in their publication in the journal ...
