  1. 1. Process Analytical Tools for the Monitoring and Characterization of Bacterial Toxins

    Författare :Martin Hedström; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; protein degradation; mass spectrometry; Bacterial toxins; Biosensor;

    Sammanfattning : In the era of proteomics, glycomics and ultimately metabolomics, with constantly increasing knowledge regarding the human biosystem, the number of specialized therapeutic agents which will be developed against different diseases is predicted to be on the upswing. An increasing portion of these new drugs will, according to recent predictions (Labrou, 2003), be of proteinaceous origin produced according to biotechnological standards. LÄS MER

  3. 2. Adaptive Responses by Transcriptional Regulators to small molecules in Prokaryotes : Structural studies of two bacterial one-component signal transduction systems DntR and HpNikR

    Författare :Cyril Dian; Peter Brzezinski; Séan McSweeney; Elisabeth Sauer-Eriksson; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transcription regulator; bacterial biosensor; LysR family; Inducer-binding; nickel-sensing; NikR; signal transduction system; Helicobacter pylori; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Prokaryotes are continually exposed to variations in their environment. Survival in unstable milieu requires a wide range of transcriptional regulators (TRs) that respond to specific environmental and cellular signals by modulating gene expression and provide an appropriate physiological response to external stimuli.

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

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

    Sammanfattning : 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. LÄS MER

  5. 4. Electrochemical (bio-)sensors operating in human physiological fluids

    Författare :Carolin Psotta; Sergey Shleev; Magnus Falk; Evgeny Katz; Malmö universitet; []
    Nyckelord :biosensor; bacteria; enzyme; sensor; physiological fluid;

    Sammanfattning : This thesis is focused on developing electrochemical (bio-)sensors specifically designed to detect biomolecules and bacteria in human physiological fluids. A more comprehensive understanding of their performance can be obtained by exposing the sensors to real human physiological fluids. LÄS MER

  7. 5. Development of Capacitive Biosensors for Monitoring of Bacterial Toxins and Other Biomolecules

    Författare :Mahmoud Labib; Bioteknik; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
