Raman tissue imaging is considered to be a unique method capable of simultaneously describing the molecular composition and the distribution of multiple chemical species in tissues at high spatial resolutions, without labeling.
Raman imaging makes use of a laser to provide a chemical fingerprint at every point of the analyzed area. One can process the data in order to reveal a multitude of information, such as:
Discriminate Diseased and Healthy Tissues
- Distinguish tissue types by their total chemical signatures – fluorescent or colorimetric labeling not needed
- Differentiate healthy and diseased tissues accurately and objectively
- No need for disease marker discovery and targeting
Clearly visualize the tissue organization with Raman images - healthy rat colon crypt.
Demarcate Tissue Regions Chemically
- Visualize anatomical layers and cell types
- Generate detailed chemical images with sub-micrometer spatial resolution
- Reveal important zonal information:
- complexity of the tissue organization
- relative abundance and distribution of chemical species
- boundary and size of diseased area
- tumor infiltration
- Unveil the morphological and chemical changes in varied samples
Understand cancer progression - examine melanoma invasion in skin construct.
Potential Pathology Tool
- Discriminate cancer stages with high specificity and sensitivity
- Determine early onset disease markers
- Detect biochemical changes linked with cancer formation and progression
- Provide histological images without labeling
- Define tumor margin
The Perfect Technique for Biological Research
- Study the concentration, conformation, distribution, redox and spin states, and orientation of biomolecules
- Compare these properties between samples
- Obtain valuable insight and improved understanding of the biological system of interest
Reveal the distribution of cells and assess their molecular profiles - neurons and glial cells in the rat brain displaying different cytochrome levels and redox states.
