Nanoscale Analysis
Tip-enhanced Raman spectroscopy (TERS) is a technique for optical spectroscopy and chemical imaging of surfaces on the nanoscale. It combines the spatial resolution of scanning probe microscopy with... Read more
Ambient Mass Spectrometry
Ambient mass spectrometry methods addresses the rapid analysis of chemicals with minimal sample preparation. There are essentially two main approaches to form ... Read more
Soft Ionization Mass Spectrometry
In recent years matrix assisted-laser disorption ionization (MALDI) and electrospray ionization (ESI) techniques have become increasingly more useful to study biomolecules.... Read more
Gas-phase Structures of Biomolecular Ions
Native electrospray ionization produces intact biomolecules and their complexes in the gas phase, but it is often unclear whether these maintain their solution-phase native conformation. We are investigating this fundamental question...Read more
