High-resolution imaging of dietary lipids in cells and tissues by NanoSIMS analysis[S] [PDF]
Journal of Lipid Research, 2014 Nanoscale secondary ion MS (NanoSIMS) imaging makes it possible to visualize stable isotope-labeled lipids in cells and tissues at 50 nm lateral resolution. Here we report the use of NanoSIMS imaging to visualize lipids in mouse cells and tissues.

New highlights of phytolith structure and occluded carbon location: 3-D X-ray microscopy and NanoSIMS results [PDF]
Biogeosciences, 2015 Phytoliths contain occluded organic compounds called phytC. Recently, phytC content, nature, origin, paleoenvironmental meaning and impact in the global C cycle have been the subject of increasing debate.

Quantitative NanoSIMS provides subcellular concentration and distribution of oligonucleotide therapeutics [PDF]
, 2023 Antisense oligonucleotides (ASOs) represent a powerful therapeutic modality that can selectively modulate gene expression. However, ASOs face two major hurdles that restrict their use in the clinic.

NanoSIMS and EPMA dating of lunar zirconolite
Progress in Earth and Planetary Science, 2021 Zirconolite is a common Zr-rich accessary mineral in mafic rocks. It is also an ideal U–Pb/Pb–Pb chronometer because it commonly contains high U content (mostly 0.1–10 wt%) and negligible initial Pb.

Heat-Affected-Zone Liquation Cracking in Welded Cast Haynes® 282®
Metals, 2019 Varestraint weldability testing and Gleeble thermomechanical simulation of the newly developed cast form of Haynes® 282® were performed to understand how heat-affected-zone (HAZ) liquation cracking is influenced by different preweld heat ...

NanoSIMS analysis of arsenic and selenium in cereal grain. [PDF]
, 2010 *Cereals are an important source of selenium (Se) to humans and many people have inadequate intakes of this essential trace element. Conversely, arsenic (As) is toxic and may accumulate in rice grain at levels that pose a health risk.
