Investigating lipid interactions and the process of raft formation in cellular membranes using ToF-SIMS.
There is an increased interest in how lipids interact with each other, especially in the lateral separation of lipids into coexisting liquid phases as this is believed to be an attribute of raft formation in cell membranes. ToF-SIMS has shown itself to be an excellent tool for investigating cellular and model membrane systems and will be perhaps the most powerful one for investigating raft form...
متن کاملTOF-SIMS in Cosmochemistry
Time-of-flight secondary ion mass spectrometry (TOF-SIMS) was introduced into cosmochemistry about a decade ago. Major advantages of TOF-SIMS compared to other ion microprobe techniques are (a) parallel detection of all secondary ions with one polarity in a single measurement – both polarities in subsequent analyses, (b) high lateral resolution, (c) sufficient mass resolution for separation of ...

متن کاملSurface Characterization of Polymer Blends by XPS and ToF-SIMS
The surface properties of polymer blends are important for many industrial applications. The physical and chemical properties at the surface of polymer blends can be drastically different from those in the bulk due to the surface segregation of the low surface energy component. X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary mass spectrometry (ToF-SIMS) have been widely used...
متن کاملApplications of TOF-SIMS in Planetology
In planetology the analysis of micrometer-sized samples like, e.g., inclusions in meteorites, interplanetary dust, and presolar grains has become more and more important. This requires techniques with high lateral resolution, no or little sample destruction, and high sensitivity. To still obtain unbiased information on this kind of samples a technique or a suite of techniques has to be selected...
