Comparing Raman and NanoSIMS for heavy water labeling of single cells [PDF]

open access: yesMicrobiology Spectrum
Stable isotope probing (SIP) experiments in conjunction with Raman microspectroscopy (Raman) or nano-scale secondary ion mass spectrometry (NanoSIMS) are frequently used to explore single cell metabolic activity in pure cultures as well as complex ...

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

open access: yesFrontiers in Microbiology, 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 ...

Isotopically Selected Co-Doping of <sup>121</sup>Sb and <sup>123</sup>Sb Pairs in Silicon. [PDF]

open access: yesAdv Mater
Pairs of 121Sb and 123Sb atoms are doped into silicon using single cluster implantation and found to reside substitutionally within the crystal lattice due to self‐annealing with a Sb‐to Sb separation of ≈2 nm. Molecular dynamics simulations reproduce the observed experimental results and single ion cluster detection efficiencies of 94% are ...

Minimal ATP-Independent N<sub>2</sub>-Reducing Systems Defined by L-Cluster-Bound Nitrogenase Assembly Platforms. [PDF]

open access: yesAngew Chem Int Ed Engl
Association of the L‐cluster with the nitrogenase assembly proteins NifEN (NifENL) or NifB (NifBL) intrinsically endows these proteins with N2‐reducing activity, enabling in vitro N2‐reduction by NifENL and NifBL when supplied with chemical reductants or photoexcited quantum dots while supporting in vivo N2‐fixation in NifENL‐ and NifENL‐expressing ...

Carbon monoxide oxidation expands the known metabolic capacity in anaerobic methanotrophic consortia [PDF]

open access: yesNature Communications
Consortia of anaerobic methane-oxidizing archaea (ANME-2) and sulphate-reducing bacteria (SRB) represent globally relevant syntrophic associations capable of growing with minimal amounts of free energy and can persist when methane becomes limiting ...

Evaluating nitrogen uptake: Methods and applications for plant research [PDF]

open access: yesApplications in Plant Sciences
Nitrogen is an essential nutrient for the growth and development of plants, aiding many physiological and biological functions. Due to the high demand for the nutrient, it is common for agricultural production systems to fertilize crop fields with large ...

H2O and Cl in deep crustal melts: the message of melt inclusions in metamorphic rocks [PDF]

open access: yesEuropean Journal of Mineralogy, 2023
The use of NanoSIMS on primary melt inclusions in partially melted rocks is a powerful approach to clarify the budget of volatiles at depth during crust formation and its reworking.

Common reef-building coral in the Northern Red Sea resistant to elevated temperature and acidification [PDF]

open access: yesRoyal Society Open Science, 2017
Coral reefs are currently experiencing substantial ecological impoverishment as a result of anthropogenic stressors, and the majority of reefs are facing immediate risk.

Calculation and Interpretation of Substrate Assimilation Rates in Microbial Cells Based on Isotopic Composition Data Obtained by nanoSIMS

open access: yesFrontiers in Microbiology, 2021
Stable isotope probing (SIP) combined with nano-scale secondary ion mass spectrometry (nanoSIMS) is a powerful approach to quantify assimilation rates of elements such as C and N into individual microbial cells.

Coalescence and directed anisotropic growth of starch granule initials in subdomains of Arabidopsis thaliana chloroplasts

open access: yesNature Communications, 2021
Starch is the major form of energy storage in plant cells and forms discrete, semi-crystalline granules within plastids. Here the authors use electron tomography and nanoSIMS to show that Arabidopsis starch granules initiate in stromal pockets between ...
