Table 1 The comparison of the analytical potential of FTIR, RS and AFM in the thrombi studies.
Thrombi feature | FTIR | RS | AFM | References |
---|---|---|---|---|
lipid content | • distribution within the whole cross–section • qualitative or semi–quantitative detection | • distribution with hi–res for chosen ROI • qualitative measurement | • form of lipids (crystals/grease material) | |
the total degree of lipids unsaturation | • semi–quantitative measurement for whole cross–section | • semi–quantitative measurement with hi–res for chosen ROI | – | |
general proteins content | • distribution for whole cross–section • qualitative or quantitative measurement | • distribution with hi–res for chosen ROI • qualitative or semi–quantitative measurement | • height and topography/stiffness of tissue | |
the ratio of lipids to proteins | • semi–quantitative measurement for whole cross–section | • semi–quantitative measurement with hi–res for chosen ROI | – | |
fibrin content | • distribution for whole cross–section • qualitative measurement • in order to build the model necessary to compare with H&E | • distribution with hi–res for chosen ROI • qualitative measurement • in order to build the model necessary to compare with H&E | • fibrin height and topography/stiffness | |
RBCs/heme | • distribution for whole cross–section • qualitative measurement | • distribution with hi–res for chosen ROI • qualitative measurement • high specificity and sensitivity to heme due to resonance effect | • height and topography/stiffness |
