  2. 1. Development of methods for determining aflatoxins in biological material

    Author : Anders Kussak; Rainer Stephany; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aflatoxins; Mycotoxins; Carcinogen; Airborne dust; Urine; Feed factories; Immunoaffinity extraction; Solid-phase extraction; Post-column derivatization; Electrospray; Mass spectrometry;

    Abstract : In this thesis, it is shown how aflatoxins can be determined in biological material. The thesis is a summary of five papers.Aflatoxins are carcinogenic mycotoxins produced by Aspergillus moulds. Methods were developed for the determination of aflatoxins in samples of airborne dust and human urine collected at feed factories. READ MORE

  4. 2. Optimization of the Sensor-Chip Surface in a Capacitive Biosensor for use in Aflatoxin Assays

    Author : Alvaro Gutierrez Rojas; Bioteknik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aflatoxin; biosensor; antibody; bioimprinting; gold nanoparticles; capacitance;

    Abstract : The capacitive biosensor technology can be utilized for the analytical detection of a variety of different compounds. By employing the electrical double-layer principle, it is possible to detect very low concentrations of the target analyte due the methods inherent high sensitivity. READ MORE

  5. 3. Mycotoxins in indoor environments. Determination using mass spectrometry

    Author : Erica Bloom; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gas chromatography; Mass spectrometry; Mycotoxin; Indoor Air; Ergosterol.; Mold; High pressure liquid chromatography; Dust; Building materials;

    Abstract : Dampness in indoor environments may cause various health problems. The specific causative agent(s) are unknown but may originate from degradation processes in damp materials, microbial growth, or a combination of these phenomena. The health impact of dampness in buildings is a politically, legally, and economically important question. READ MORE
