Secondary ion mass spectrometry imaging of Dictyostelium discoideum aggregation streams. [PDF]

open access: yesPLoS ONE, 2014
High resolution imaging mass spectrometry could become a valuable tool for cell and developmental biology, but both, high spatial and mass spectral resolution are needed to enable this.

Imaging and quantitative analysis of insecticide in mosquito net fibers using Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS). [PDF]

open access: yesPLoS ONE, 2018
Time-of-flight secondary ion mass spectrometry (ToF-SIMS) analysis was used to qualitatively and quantitatively assess the distribution of permethrin insecticide on the surfaces and interiors of Olyset long-lasting insecticidal net (LLIN) fibers.

Towards practical time-of-flight secondary ion mass spectrometry lignocellulolytic enzyme assays. [PDF]

open access: yesBiotechnol Biofuels, 2013
Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) is a surface sensitive mass spectrometry technique with potential strengths as a method for detecting enzymatic activity on solid materials. In particular, ToF-SIMS has been applied to detect the enzymatic degradation of woody lignocellulose.

Lipid imaging with time-of-flight secondary ion mass spectrometry (ToF-SIMS). [PDF]

open access: yesBiochim Biophys Acta, 2011
Fundamental advances in secondary ion mass spectrometry (SIMS) now allow for the examination and characterization of lipids directly from biological materials. The successful application of SIMS-based imaging in the investigation of lipids directly from tissue and cells are demonstrated. Common complications and technical pitfalls are discussed.
