  1. 1. On the Road to Graphene Biosensors

    Författare :Malkolm Hinnemo; Zhi-Bin Zhang; Shi-Li Zhang; Jörgen Olsson; Max Lemme; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; Biosensors; Microprocessing; Photolithography; Surface Physics; Raman Spectroscopy; Transistors; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : Biosensors are devices that detect biological elements and then transmit a readable signal. Biosensors can automatize diagnostics that would otherwise have to be performed by a physician or perhaps not be possible to perform at all. Current biosensors are however either limited to particular diseases or prohibitively expensive. LÄS MER

  3. 2. Development of Electrochemical Biosensors for Neurochemical Applications

    Författare :Jenny Bergman; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biosensors; electrochemistry; neurochemistry;

    Sammanfattning : The brain consists of billions of cells, including nerve cells, which have the ability of transforming an incoming electrical signal in to a chemical output by the release of neurotransmitters through a process called exocytosis. Malfunction in neuronal communication has been linked to several conditions including Parkinson’s disease, schizophrenia, ADHD and autism why a better understanding of neuronal communication is of great importance contributing to increased knowledge about these conditions.

  4. 3. Photochemical Ligation Techniques for Carbohydrate Biosensors and Protein Interaction Studies

    Författare :Oscar Norberg; Olof Ramström; Stéphane Vincent; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; Biosensors; CuAAC; Photochemistry; Thiol-ene yne; Perfluorophenylazide PFPA ; Lectins; Molecular recognition; Quartz crystal microbalance QCM ; Surface plasmon resonance SPR ;

    Sammanfattning : This thesis concerns the development of surface ligation techniques for the preparation of carbohydrate biosensors. Several methodologies were developed based on efficient photochemical insertion reactions which quickly functionalize polymeric materials, with either carbohydrates or functional groups such as alkynes or alkenes.

  5. 4. Nanofabrication of Single Electron Transistors and Evaluation of Miniature Biosensors

    Författare :Linda G. M. Olofsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; miniaturization; nanoparticles; impedance; single electron tunneling; biosensors; surface plasmon resonance;

    Sammanfattning : This thesis deals with miniaturization in two different fields: electronics and biosensing. The first part deals with fabrication and measurements of two nanoscale structures - a self-assembled single electron transistor and a (potential) single junction device. LÄS MER

  7. 5. Evaluation of biosensors and flow cytometry as monitoring tools in lignocellulosic bioethanol production

    Författare :Raquel Perruca Foncillas; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saccharomyces cerevisiae; Biosensors; Flow cytometry; Bioethanol production; Lignocellulosic biomass; Xylose; Strain engineering; Lignocellulosic ethanol; Lignocellulosic inhibitors; Furfural;

    Sammanfattning : The significant environmental impact of the current fossil fuel-based industry is a major concern for society. Consequently, various initiatives are being undertaken to establish a more sustainable industrial model. LÄS MER
