Abstract
The analysis of macromolecules - such as proteins - pose a significant bottleneck in analytical science. We have developed surface treatment techniques utilising direct and radiofrequency current argon plasmas, able to quickly digest condensed-phase macromolecules while maintaining spatial resolution of analytes. We show here that these plasmas can be powerful tools for mass spectrometry imaging of peptides and proteins.
