Meta-NanoSim: metagenome simulator for nanopore reads

, 2020
As a long-read sequencing technique, Oxford Nanopore Technology (ONT) has shown unprecedented potential in metagenomic studies. However, the challenges associated with ONT reads, such as high error rate and non-uniform error distributions, necessitate analytical tools designed specifically for long reads. To facilitate the development and benchmarking,

Virus and Bacterial Cell Chemical Analysis by NanoSIMS

, 2008
In past work for the Department of Homeland Security, the LLNL NanoSIMS team has succeeded in extracting quantitative elemental composition at sub-micron resolution from bacterial spores using nanometer-scale secondary ion mass spectrometry (NanoSIMS). The purpose of this task is to test our NanoSIMS capabilities on viruses and bacterial cells.

NanoSIMS and more: New tools in nuclear astrophysics

Journal of Physics: Conference Series, 2016
Primitive Solar System materials contain nm- to μm-sized presolar grains that formed in the winds of evolved stars and in the ejecta of stellar explosions. These samples of stardust can be analysed in terrestrial laboratories with sophisticated analytical instrumentation in great detail.
