Correlated cryo-SEM and CryoNanoSIMS imaging of biological tissue

BMC Biology, 2023
Background The development of nanoscale secondary ion mass spectrometry (NanoSIMS) has revolutionized the study of biological tissues by enabling, e.g., the visualization and quantification of metabolic processes at subcellular length scales.

SIMSISH technique does not alter the apparent isotopic composition of bacterial cells. [PDF]

PLoS ONE, 2013
In order to identify the function of uncultured microorganisms in their environment, the SIMSISH method, combining in situ hybridization (ISH) and nanoscale secondary ion mass spectrometry (nanoSIMS) imaging, has been proposed to determine the ...

Coordinated TEM and NanoSIMS of Presolar Graphites [PDF]

Microscopy and Microanalysis, 2005
Presolar graphites are especially interesting in that they encapsulate many internal grains during their growth, preserving these higher temperature phases that condense in the outflows of supernova (SN) and carbon stars. Coordinated laboratory microanalysis of these phase assemblages, using transmission electron microscopy and then secondary ion mass ...

Electron microscopic imaging and NanoSIMS investigation on physiological responses of Aspergillus niger under Pb(II) and Cd(II) stress

Frontiers in Bioengineering and Biotechnology, 2023
In the bioremediation process, coexistence of lead (Pb) and cadmium causes complex toxicity, resulting in the difficulty of bioremediation. This study investigated the physiological responses and bioaccumulation mechanisms of the typical filamentous ...

NanoSIMS analysis of water content in bridgmanite at the micron scale: An experimental approach to probe water in Earth’s deep mantle

Frontiers in Chemistry, 2023
Water, in trace amounts, can greatly alter chemical and physical properties of mantle minerals and exert primary control on Earth’s dynamics. Quantifying how water is retained and distributed in Earth’s deep interior is essential to our understanding of ...

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.
