System and method for cytological analysis by raman spectroscopic imaging

InactiveUS20070178067A1Superior resolution and intensitySensitive assessmentBiocideGenetic material ingredientsBiological StressData set
A method and system of differentially manipulating cells where the cells, suspended in a fluid, are irradiated with substantially monochromatic light. A Raman data set is obtained from the irradiated cells and where the data set is characteristic of a disease status. The data set is assessed to identify diseased cells. A Raman chemical image of the irradiated cells is also obtained. Based on the assessment and the Raman chemical image, the fluid in which the cells are suspended is differentially manipulated. The diseased cells are directed to a first location and other non-diseased cells are directed to a second location as part of the differential manipulation. The diseased cells may be treated with a physical stress, a chemical stress, and a biological stress and then returned to a patient from whom the diseased cells were obtained prior to the irradiation.
