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.

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.

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 ...

Elemental and Isotopic Imaging of Biological Samples Using NanoSIMS

2013
With its low detection limits and the ability to analyze most of the elements in the periodic table, secondary ion mass spectrometry (SIMS) represents one of the most versatile in situ analytical techniques available, and recent developments have resulted in significant advantages for the use of imaging mass spectrometry in biological and biomedical ...

Oxygen isotopic measurements on the Cameca Nanosims 50

Applied Surface Science, 2003
Abstract The Cameca Nanosims 50 has been designed to provide for parallel detection along a focal plane over a large mass range but spacing between adjacent mass lines makes it necessary to use miniature electron multipliers (EMs). A new version of a miniature EM, designed to reduce aging effects, has been tested.

Facing hazardous matter in atmospheric particles with NanoSIMS.

Environmental science and pollution research international, 2007
Current scientific studies and evaluations clearly show that an increase of urban dust loads, alone or in combination with other air pollutants and certain meteorological conditions lead to different significant health effects. Premature death, increased hospital admissions and increased respiratory symptoms and diseases as well as decreased lung ...
