  1. 6. Biosensor-based Methods for Detection of Microcystins as Early Warning Systems

    Författare :Lesedi Lebogang; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microcystins; Drinking water; Adda-specific monoclonal antibodies; Biosensors; Capacitive; Amperometric; Flow-ELISA; Microcontact imprinting;

    Sammanfattning : Cyanobacteria blooms are a water menace since they produce potent toxins that have been implicated in poisonings and deaths of humans and animals after consumption or contact with cyanotoxin-contaminated water. Of particular concern are cyanotoxins called microcystins, which are hepatotoxic cyclic peptides known to promote development of liver tumors in humans and animals. LÄS MER

  3. 7. Protein-based capacitive biosensors for the detection of heavy-metal ions

    Författare :Alessia Mortari; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heavy metal ions; protein; electrode; Biosensor; capacitance;

    Sammanfattning : Some metal ions, such as copper and zinc, are essential nutrients and catalysts in biochemical reactions. Other metal ions, e.g. cadmium and mercury, are highly toxic elements. LÄS MER

  4. 8. Design and development of electrochemical sensors with application in bioanalysis

    Författare :Kinga Zor; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioanalysis; electrochemistry; sensor; biosensor; miniaturization; real sample; immunoassay; μTAS;

    Sammanfattning : There is a continuous search for reliable, robust, easy to use, portable and cost effective analytical tools with applications in food industry, biomedicine, environmental monitoring and homeland security. The main focus of this thesis is the development of electrochemical (bio)sensors and bioanalysis systems (to be applied in two major fields of interest: food & beverage industry and biomedical research) for monitoring key analytes in complex matrices, such as: meat samples, fermentation broths, and cell culture media.

  5. 9. Use of Biorecognition Elements or Their Mimics in New Flow Analysis Systems

    Författare :Bjarni Bjarnason; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; solid phase extraction; molecular imprinting; flow immunoassays; Capacitve biosensor; thermal biosensor; Analytisk kemi;

    Sammanfattning : We have evaluated capacitive and thermal transducers for recognition of bio- molecular interactions with different analytes. These assays were made in flow analysis systems because of the simplicity such methods provide. LÄS MER

  7. 10. Microfluidic biosensor systems for cardiotoxicity assaying

    Författare :Gunnar Bergström; Carl-Fredrik Mandenius; Nate Robinson; Staffan Nilsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Toxicity screening is an important part of pharmaceutical development and early detection of toxic side effects provide the opportunity for early redesign or termination of unfeasible projects. Today toxicity testing is relying on experiments on animals. LÄS MER
