Simultaneous analysis of microbial identity and function using NanoSIMS [PDF]

Environmental Microbiology, 2008
Summary Identifying the function of uncultured microbes in their environments today remains one of the main challenges for microbial ecologists. In this article, we describe a new method allowing simultaneous analysis of microbial identity and function.

Table_1_Calculation of Single Cell Assimilation Rates From SIP-NanoSIMS-Derived Isotope Ratios: A Comprehensive Approach.XLSX

, 2018
The nanoSIMS-based chemical microscopy has been introduced in biology over a decade ago. The spatial distribution of elements and isotopes analyzed by nanoSIMS can be used to reconstruct images of biological samples with a resolution down to tens of ...

Micro-scale (1 μm) Mg isotope analysis of olivine by NanoSIMS with online matrix correction and its application to Chang'e-5 sample.

Talanta: The International Journal of Pure and Applied Analytical Chemistry
In-situ stable Mg isotope analysis of olivine, the most common mineral in igneous and metamorphic rocks, provides critical insights into their formation and timescales. However, accurate correction of significant matrix effects is hampered by the lack of

Detecting metabolic activities in single cells, with emphasis on nanoSIMS [PDF]

FEMS Microbiology Reviews, 2012
Investigating the contribution of microbial populations to biochemical processes of global significance is challenging as there are few approaches that can detect microbial metabolic activities on single-cell level. Given the widespread distribution and importance of microorganisms in elemental transformations, improved methods for measuring microbial ...

Carbon fixation from mineral carbonates

Nature Communications, 2017
Evidence showing that carbonates can directly supply CO2 for autotrophy is lacking. Here, using stable isotope analyses and NanoSIMS imaging, the authors show that a model euendolith, Mastigocoleus testarum strain BC008, derives the majority of its ...

Uptake, localization and dissolution of barium sulfate nanoparticles in human lung cells explored by the combination of ICP-MS, TEM and NanoSIMS.

Journal of Trace Elements in Medicine and Biology
BACKGROUND Barium sulfate nanoparticles (BaSO4-NPs) are considered to be poorly soluble, chemically inert, and therefore relatively non-toxic. For humans, inhalative exposure represents the most significant route of uptake.

Characterising hydrogen induced cracking of alloy 625+ using correlative SEM - EDX and NanoSIMS

Corrosion Science, 2021
Hydrogen induced cracking behaviour of O&G nickel alloy 625+ (UNS N07716) was investigated. Deuterium was introduced electrochemically into samples by cathodic polarisation (3.5 wt.% NaCl.D2O) under different mechanical conditions.

High-resolution visualization and quantification of nucleic acid–based therapeutics in cells and tissues using Nanoscale secondary ion mass spectrometry (NanoSIMS)

Nucleic Acids Research, 2020
Nucleic acid therapeutics (NATs) have proven useful in promoting the degradation of specific transcripts, modifying gene expression, and regulating mRNA splicing.
