Depth Correction of 3D NanoSIMS Images Shows Intracellular Lipid and Cholesterol Distributions while Capturing the Effects of Differential Sputter Rate.

ACS Nano, 2022
Knowledge of the distributions of drugs, metabolites, and drug carriers within cells is a prerequisite for the development of effective disease treatments. Intracellular component distribution may be imaged with high sensitivity and spatial resolution by

NanoSIP: NanoSIMS Applications for Microbial Biology

2012
Recent advances in high-resolution imaging secondary ion mass spectrometry (SIMS) (J Biol 5: 20, 2006) have made isotopic tracing at the single-cell level a standard technique for microbial ecology and systems biology; elemental and metal cofactor analyses are also showing significant promise.

Impact of Rhizosphere Biostimulation on Cd Transport and Isotope Fractionation in Cd-Tolerant and Hyperaccumulating Plants Based on MC-ICP-MS and NanoSIMS.

Environmental Science and Technology
Phytoremediation efficiency can be enhanced by regulating rhizosphere processes, and the Cd isotope is a useful approach for deciphering Cd transport processes in soil-plant systems.

NanoSIMS analysis of Archean fossils and biomarkers

Applied Surface Science, 2008
Abstract The study of fossils and biomarkers from Archean rocks is of vital importance to reveal how life arose on Earth and what we might expect to find on other planets such as Mars. The Cameca NanoSIMS 50 has the unique ability to measure stable isotopes and map biologically relevant elements at the micron-scale, in situ. This makes it the perfect

NanoSIMS perspectives for nuclear astrophysics

New Astronomy Reviews, 2002
Abstract Primitive meteorites contain small quantities of presolar grains with highly anomalous isotopic compositions. These grains formed in stellar atmospheres or in the ejecta of stellar explosions and they represent a sample of stardust that can be analyzed with high precision in the laboratory.

Microbialite taphonomy and biogenicity: new insights from NanoSIMS

Geobiology, 2010
AbstractWe here show that nano‐scale mapping of elements commonly utilized in biological cycles provides a promising new additional line of evidence when evaluating the extent of the contribution of biology to microbialites. Our case study comes from Lake Clifton in Western Australia, a unique environment where living domical and conical microbialites ...

Diversity in the Archean Biosphere: New Insights from NanoSIMS

Astrobiology, 2010
The origin of organic microstructures in the approximately 3 Ga Farrel Quartzite is controversial due to their relatively poor state of preservation, the Archean age of the cherts in which they occur, and the unusual spindle-like morphology of some of the forms.
