  • Raman frequency dispersion studies of substituted polythiophene films

    Styryl substituted terthiophene species have been used to produce neutral polythiophene species which show distinct Raman frequency dispersion. The polythiophene line B band shows dispersion values of: -0.12, -0.07, -0.1 cm−1 nm−1 for the phenyl, para-methoxy phenyl and para-cyano phenyl systems respectively. This is smaller than the dispersion values reported for polythiophene presumably because ...

  • Raman ‘optical biopsy’ of human breast cancer

    Abstract Raman imaging (RI) is a novel method of medical diagnostics of human breast cancer and has a potential to become a routine optical biopsy. Up to date the present study is the most statistically reliable Raman analysis based on data of normal, benign, and cancerous breast tissues for 146 patients. This paper present the first Raman ‘optical biopsy’ images of the ...

  • Identification of forensic fabrics using a portable Raman spectrometer

    At a crime scene, a police officer collects a fiber sample that may prove to be invaluable evidence in identifying a criminal or exonerating an innocent person. While FTIR has been used for analysis in the past, the strong absorption of the fabric or the glass slide where it is mounted makes the spectrum very hard to interpret. In recent years, Raman spectroscopy has been studied extensively for ...

  • A Raman-based endoscopic strategy for multiplexed molecular imaging

    Endoscopic imaging is an invaluable diagnostic tool allowing minimally invasive access to tissues deep within the body. It has played a key role in screening colon cancer and is credited with preventing deaths through the detection and removal of precancerous polyps. However, conventional white-light endoscopy offers physicians structural information without the biochemical information that would ...

  • Raman imaging at biological interfaces: applications in breast cancer diagnosis

    Abstract Background: One of the most important areas of Raman medical diagnostics is identification and characterization of cancerous and noncancerous tissues. The methods based on Raman scattering has shown significant potential for probing human breast tissue to provide valuable information for early diagnosis of breast cancer. A vibrational fingerprint from the ...

  • Building analytical competence for geoscience students through use of Raman spectroscopy

    Introduction: Traditionally, a geologist's analytical toolkit consisted of a hand lens, rock hammer, acid bottle, magnet, and perhaps a polarizing light microscope back in the laboratory. In geoscience professions, these tools are increasingly being supplemented by field and laboratory instrumentation that utilizes spectroscopy. The availability of newly-developed, lower-priced ...

  • Measurement of temperature gradients through local extinction using Raman scattering spectroscopy

    Measurements of temperature in laminar flames with localised extinction points were made using line imaging of spectrally resolved laser Raman scattering through the extinction process. A fit to the nitrogen scattering spectrum was used to determine temperature with an accuracy of 30 K. Temperature gradients through the extinction process were measured as the flame strength prior to extinction ...

  • Replacement of 130 ft Secondary Clarifiers at a 25 MGD wastewater treatment facility

    Challenge A municipal WWTP found that (2) of their secondary clarifiers were too rusted and corroded to properly function. A traditional clarifier refurbishment consisting of sandblasting and painting was not a viable option because one of the clarifier rake arms had recently broken due to its poor condition. The plant engineers decided that a clarifier rebuild was necessary to ensure ...
