Mass Spectral Imaging
The overall goal of our research is to develop techniques for improved analysis of the biomolecule-surface interfaces and multimodal imaging of biologically relevant samples. The ability to get sub-cellular images of cell and tissues with chemical and molecular specificity opens up a range of possibilities for better understanding and diagnosing biological processes such as tumor microenvironments, lipid metabolomics relationship to cancer, tissue repair, and chemical analysis of tissue and/or cells on a cellular and sub-cellular level. One technique capable of acquiring this information is secondary ion mass spectrometry (SIMS). We have developed many new tools and capabilities to improve sub-cellular resolution ToF-SIMS analysis of cells and tissues. Our research involves development of the sample preparation, technique development, data processing, and data analysis which is critical to make this technology more applicable to the biological/medical community.
Our work and advances in ToF-SIMS imaging and data processing has prompted significant interest among biomedical academic as well as the clinical research community. Utilizing the newer cluster ion sources allows us to get 3-D images of cells and tissues as well. We continue to further advancement in this area with the addition of new instrumentation as well as improved data processing. Newer advancements have involved image registration to correlate image data acquired on different techniques and statistical analysis of multiple data.
