1. Single fluid inclusion analysis using ToF-SIMS : Implications for ancient Earth biodiversiy and paleoenvironment studies
Sammanfattning : When and how life first emerged on the Earth is an area of intense research. Signs of the first life on Earth, including morphological fossils, are scarce and hard to interpret. An alternative approach is to study organic biomarkers, which are molecular fossils commonly considered as bona fide biosignatures. LÄS MER
2. Application of imaging TOF-SIMS in cell and tissue research
Sammanfattning : This thesis is aimed at extending the use of TOF-SIMS (time of flight secondary ion mass spectrometry) as an analytical tool in cell and tissue research. TOF-SIMS is a relatively new method that allows analysis of the chemical composition of sample surfaces. LÄS MER
3. Identification and imaging of lipids in tissues using TOF-SIMS
Sammanfattning : Introduction: Normal lipid metabolism in the adipose tissue, skeletal muscle and aortic wall is important for the physiological function of these tissues. Dyslipidemia that is often associated with intake of high energy diet and sedentary lifestyles can lead to the development of insulin resistance and cardiovascular diseases. LÄS MER
4. Development and Application of ToF-SIMS for Clinical and Microbiological Analysis
Sammanfattning : The aim of the work of this thesis was to further the implementation of timeof-flight secondary ion mass spectrometry (ToF-SIMS) in biological analysis and to generate new knowledge from the samples analysed. ToF-SIMS is a chemical analysis technique. LÄS MER
5. ToF-SIMS as a tool for analysing organic material in geological samples -Fluid inclusions and beyond
Sammanfattning : In situ analysis of organic material in rocks has potential to answer questions in geochemistry, astro- and geobiology. Recently, successful studies which included in situ analyses of geological samples with time-of-flight secondary ion mass spectrometry (ToF-SIMS) were carried out. LÄS MER
