Trace elements are non-homogenously distributed in brain tissue, the distribution depends on the element. There is some research indicating that trace elements, in particular Fe, Cu and Zn, are associated with neurodegenerative diseases.
This project is about developing quantification methods for elemental imaging of brain thin sections. You will have to develop suitable standard materials and methods for calibration for the quantification of essential and non-essential elements present in tissue using laser ablation ICP-MS as measurement method. The development of internal standardisation using eg rhodium as non-biological element is another part of the project. The method has to be cross-validated using total element determination in the prepared standards and test-samples.
The developed method will then be applied to biological tissues of varying origin.
Quantitative LA-ICP-MS (laser ablation ICP-MS) of biological tissue
- Develop standard materials
- Develop calibration methods
- Develop internal standardisation methods
- Cross-validate LA-ICP-MS results with results from total digestion
- Apply developed method to brain thin sections of rats and different murine AD models
Candidates should have (or expect to achieve) a UK honours degree at 2.1 or above (or equivalent) in Analytical Chemistry. It is essential that the successful candidate has a solid knowledge in basic instrumental analytical chemistry. Knowledge of ICP-MS and laser ablation system is preferred.
