  1. 1. Development of Ultra-fast Biosensors for Detection of Non-electroactive Neurotransmitters

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Yuanmo Wang; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; artificial cell; quantification; stability; deformation; dynamic light scattering; adsorption; amperometry; nanoparticle tracking analysis; enzyme monolayer; glucose oxidase; exocytosis; choline oxidase; acetylcholine; enzymatic activity; acetylcholine esterase; gold nanoparticles; Biosensor;

    Sammanfattning : During neuronal communication neurotransmitters are released through the process exocytosis that occurs on the time scale of sub-milliseconds to milliseconds. Neuronal activity by neurotransmitters that are non-electroactive cannot easily be monitored due to limitations in the temporal resolutions of the sensor probes for these analytes. LÄS MER

    Sammanfattning : The work described in this thesis has the focus on the development of new analytical tools to study processes related to cellular secretion (exocytosis) in cell models. Four novel techniques were developed, allowing new ways to study processes related to exocytosis, and gain previously unattainable knowledge. LÄS MER

  4. 4. Polypeptide Conjugates as High-affinity Binders for Proteins

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Lotta Tollstoy Tegler; Uppsala universitet.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein recognition; polypeptide conjugates; peptide; molecular interactions; C-reactive protein; Acetylcholine esterase; Human Carboinc anhydrase; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : A novel concept for protein recognition has been developed. The recognition unit is a hybrid molecule obtained by conjugation of a small organic molecule to a synthetic polypeptide selected from a 16-membered set of 42 amino acid residue sequences. The sequences are unordered and have no prior relation to the target proteins. LÄS MER
