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

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

    Abstract : 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. READ MORE

  4. 2. Development of Capacitive Biosensors for Monitoring of Bacterial Toxins and Other Biomolecules

    Author : Mahmoud Labib; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; enzyme-linked immunosorbent assay; self-assembled monolayers; competitive capacitive biosensing; cholera toxin; Capacitive biosensor; surface plasmon resonance; staphylococcal enterotoxin B; nanogold; human immunoglobulin G; glucose;

    Abstract : Sensing and quantification of biomolecules are becoming increasingly important in medical diagnostics, bioprocess technology and recently in homeland security. The majority of techniques currently employed to interrogate biomolecules require some type of radio-, enzymatic- or fluorescent-labeling. READ MORE

  5. 3. Affinity biosensors based on a capacitive transducer

    Author : Christine Berggren; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; self-assembled monolayers; capacitance; heavy metal ion; non-labeled; nucleic acid; DNA biosensor; Biosensor; immunosensor; Analytical chemistry; Analytisk kemi;

    Abstract : Capacitive biosensors were developed for several analytes such as hormones, interleukines, viruses and heavy metal ions. The sensing surfaces were prepared by immobilizing the biorecognition element to self-assembled monolayers (SAMs) on gold. SAMs form spontaneously on gold by adsorption of thiols, sulfides or disulfides. READ MORE

  6. 4. Design, Development and Applications of Highly Sensitive Protein-Based Capacitive Biosensors

    Author : Ibolya Bontidean; Kemiska institutionen; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; Contaminated soil; Heavy metals; Lac repressor; Phytochelatin; MerP; MerR; SmtA; Self-assembled monolayer; Biosensor; Capacitance;

    Abstract : Highly sensitive biosensors were developed for environmental and medical applications. The biosensors were based on bioengineered proteins as biorecognition elements coupled to a highly sensitive capacitive transducer. READ MORE

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

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

    Abstract : 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. READ MORE
