This opportunity focuses on the measurement development and subsequent application of new desorption mass spectrometry-based platforms for studying biological materials (such as single cells) and nanoscale materials (such as engineered nanoparticles). Specifically, secondary ion mass spectrometry (SIMS) and ambient ionization mass spectrometry (AI-MS) are utilized to study the surface chemistry of biological and nanoscale samples, including the two- and three-dimensional chemical distributions of pertinent signatures. Both time-of-flight and magnetic sector-based SIMS instruments are available for these studies depending on the particular aims of the chosen project. Additionally, atmospheric pressure triple quadrupole instruments are available for extending the biological and nanoscale characterizations to challenging sample environments.
