2. 1. New Electrochemical Tools to Study Exocytosis

   Author : Joakim Wigström; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; amperometry; QCM-D; micro electrode array; large dense core vesicles; chromaffin cells; PC-12 cells; microelectrode; exocytosis; electrochemical cytometry; electrochemical imaging; acetylcholine; endocytosis; nanoparticles; enzyme biosensor; microfabrication;

   Abstract : 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. READ MORE

4. 2. Development of electrochemical sensor and biosensor platforms : detection of therapeutic drugs and heavy metal ions

   Author : Sereilakhena Phal; Solomon Tesfalidet; Britta Lindholm-Sethson; William Siljebo; Pankaj Vadgama; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sensors; electrode surface modification; electrochemical immitance spectroscopy; square wave anodic stripping voltammetry; singular value decomposition; therapeutic drugs; heavy metals;

   Abstract : Electrochemical sensors and biosensors combine the sensitivity of electroanalytical methods with the selectivity of a sensor or biosensor surface. The chemical or biochemical component (receptor) in the sensor recognizes an analyte and produces an electrical signal which is proportional to the analyte concentration. READ MORE

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

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

   Abstract : 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. READ MORE

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

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

   Abstract : 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.

7. 5. Cellobiose dehydrogenase on electrodes - an electrochemical biosensor for various analytes tunable by positive charges

   Author : Christopher Schulz; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cellobiose dehydrogenase; direct electron transfer; amperometric biosensor; glucose; lactose; cellobiose; calcium; polycation; graphite; gold; electrode;

   Abstract : Cellobiose dehydrogenase (CDH) is a sugar oxidizing enzyme secreted by various species of wood degrading fungi to assist the process of wood degradation. It can oxidise analytically relevant sugars as cellobiose, lactose or glucose leading to a gain of two electrons per sugar molecule. READ MORE
