  • Patent number: 8553732
    Abstract: A method for generating an image of a sample that is informative of the disease state of a cell in the sample. A sample including the cell is irradiated with monochromatic light. The Raman scattered light is assessed. A digital brightfield image of the Raman scattered light is generated and combined with the Raman scattered light emitted by the cell whereby the Raman scattered light is informative of the disease state of the cell in the sample. The method can also be used to determine the metabolic activity of the cell, the inflammatory status of the cell and/or the infected status of the cell in the sample.

  • Publication number: 20070178067
    Abstract: 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.

  • Patent number: 7239383
    Abstract: The embodiments disclosed herein generally relate to identifying and removing background noise in spectroscopic imaging of a sample. Because white-light has essentially constant intensity at every wavelength, background noise caused by white light can be identified and removed from spectroscopic measurements including Raman spectroscopy. Thus, once the Raman spectrum for a sample is obtained, it may be corrected to remove the white-light dispersive spectrum in accordance with the embodiments disclosed herein.

  • Publication number: 20060276697
    Abstract: The invention relates to methods and devices for assessing one or more blood components in an animal. The present invention permits non-invasive assessment of blood components in a body structure containing blood and other tissue types by assessing multiple regions of a tissue surface for an optical characteristic of blood and separately assessing one or more optical (e.g., Raman or NIR) characteristics of the blood component for one or more regions that exhibit the optical characteristic of blood.

  • Publication number: 20060250613
    Abstract: A method and apparatus for imaging biological objects. A SERS surface is provided having enhancing structures uniformly distributed on the surface. The surface includes a two dimensional area of at least 5×105 nm. The enhancing structures may have a size, in at least one dimension of height, width and length, ranging from 100 nm to 1000 nm. A biological material is deposited on the SERS surface. The biological material on the SERS surface is illuminated using a monochromatic light source producing Raman scattered photons. The Raman scattered photons are filtered using a tunable filter into a plurality of predetermined wavelength bands. A two-dimensional array detector detects the filtered Raman scattered photons, in a spatially accurate manner. The results of filtering and detecting steps are combined to produce a plurality of spectrally resolved Raman images of the biological material.

  • Publication number: 20060001868
    Abstract: The disclosure relates to a substrate material for the improved detection, resolution and imaging of biological material for spectroscopic characterization by Raman of optical imaging spectroscopy. The substrate provides a uniform, optically flat, highly reflective surface which can be made hydrophobic to prevent spreading of the sample and facilitating its optical evaluation. Moreover, the substrate can be coated with a material that does not emit Raman scattered photons when exposed to said illuminating photons. The principles disclosed herein allow a low spectroscopic background particularly suitable for examining small samples or samples having low concentrations of the suspected component.

  • Publication number: 20050277816
    Abstract: Raman molecular imaging is used to differentiate between normal and diseased cells or tissue. For instance benign and malignant lesions of bladder and other tissues can be distinguished, including epithelial tissues such as lung, prostate, kidney, breast, and colon, and non-epithelial tissues, such as bone marrow and brain. Raman scattering data relevant to the disease state of cells or tissue can be combined with visual image data to produce hybrid images which depict both a magnified view of the cellular structures and information relating to the disease state of the individual cells in the field of view.
