With respect to the former, we are developing a functional near-video rate Raman spectral imaging device and associated novel analysis tools that will allow biologists, medical professionals, and biomedical engineers to track cell phenotype and activity, the chemical composition of extracellular matrix, as well as the morphological and chemical properties of synthetic tissue scaffolds.
As far as the latter is concerned, the putative cancer stem cell has been proposed to be responsible in the developmental stages of some cancers. The goal on this front, is to be able to phenotypically map cancerous and normal tissue in an effort to discover correlations of this and other theories about cancer development utilizing bCARS spectral imaging. More specifically, in a bottom-up approach, beginning with the analysis of multicomponent biopolymer solutions to individual cells and, eventually, whole tissue, the hope is to build more robust models of cancer development as well as to develop standards for phenotype mapping in whole tissue for the medical community. Also, in an effort to develop quality control and characterization tools for the ever-changing biopharmaceutical industry, we are undertaking the initial phases of bringing CARS microscopy into the realm of tablet surface imaging. Utilizing an epi-detection CARS microscope design, we are imaging model tablet systems to detect crystalline forms of the active ingredients separately from the amorphous excipients.
