  1. 1. Creating Ultrafast Biosensors for Neuroscience

    Author : Yuanmo Wang; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; quantification; glucose; choline oxidase; gold nanoparticles; enzyme monolayer; enzymatic activity; Biosensor; adsorption; brain slice; enzyme stability; acetylcholine esterase; artificial cell; exocytosis; glucose oxidase; deformation; glutamate; glutamate oxidase; acetylcholine; amperometry;

    Abstract : Neuronal communication is the basis for all our brain function and relies on regulated exocytosis, a cell function that involves release of quantal amounts of neurotransmitters into the gap space between interconnected neurons to serve as chemical signals. To study exocytosis, which is a fast process that occurs on the timescale of sub-milliseconds to milliseconds, a toolbox of analytical methods has been developed where the electrochemical based techniques offer quantitative and sufficient high temporal recording speed.

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

    Author : Yuanmo Wang; Chalmers University of Technology; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 4. Amperometric Carbon Paste Biosensors Based on Horseradish Peroxidase and Oxidases

    Author : Vijayakumar Rajendran; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; on-line monitoring; l-lactate; glucose; ethanol; Biosensor; Carbon paste; Analytisk kemi;

    Abstract : Amperometric carbon paste peroxide sensors based on horseradish peroxidase (HRP) were developed. In the first approach, HRP was chemically modified with polyethylene glycol to improve the stability of the enzyme in the organic paste matrix and compared with native HRP electrode. READ MORE

  5. 5. Adrenergic signaling in insulin-sensitive tissues

    Author : Daniel L. Yamamoto; Tore Bengtsson; Barbara Cannon; Michael Cawthorne; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Adrenergic; Glucose; Signaling; Skeletal muscle; Animal physiology; Zoofysiologi; zoofysiologi; Zoological physiology;

    Abstract : Glucose metabolism in insulin-sensitive tissues such as skeletal muscle and adipose tissue is tightly regulated by external stimuli. Metabolic changes in these tissues have direct effects on whole body metabolism. Such metabolic changes can be induced or influenced by adrenergic stimulation. READ MORE
