“Photoacoustic Flow Cytometry: Detection of Pathological Analytes in Blood”
Photoacoustic flow cytometry is a method to detect and capture pathological analytes in body fluids by exploiting optical absorption in cells of interest while ignoring other cells. For instance, natural pigment in melanoma cells provides the optical discrimination necessary against a back-ground of normal blood cells so that these cancer cells can be monitored in blood samples of patients. Photoacoustic ow cytometry uses an excitation laser to induce pressure waves in pig-mented cells under ow, so that the generated signals can be counted and tracked for downstream capture and further analysis of these cells. We have used this system for detection and capture of melanoma, breast cancer, and prostate cancer cells in blood, as well as in detection of malaria parasites. Most recently, we have engineered bacteriophages to provide pigment to bacterial cells in order to develop a rapid means for detecting bacteria in blood. …Read Bio

“Chemical Imaging: Sensors That Make Our World Healthier and Safer”
Chemical or Hyperspectral Imaging is the combination of spectroscopy with the power of digital imaging to reveal chemical-based details of the world. This talk will provide examples of how ChemImage Sensor Systems has developed hyperspectral imaging systems for the detection of chemicals in the environment, ingredient-specific particle sizing for pharmaceuticals and standoff detection of explosives at entry control points. In addition, this talk will discuss how one standoff hyperspectral mode can be used to target another in order to dramatically improve the area search rate for the detection of chemicals and explosives. Details of the instrumentation and software that enable these applications of hyperspectral imaging will be presented. …Read Bio
