  2. 1. Biosensor surface chemistry for oriented protein immobilization and biochip patterning

    Author : Emma Ericsson; Karin Enander; Sofia Svedhem; Linköpings universitet; []
    Keywords : Biochip; biosensor; hydrogel; ligand; orientation; patterning; photochemistry; protein immobilization; surface chemistry; self-assembled monolayer; SAM;

    Abstract : This licentiate thesis is focused on two methods for protein immobilization to biosensor surfaces for future applications in protein microarray formats. The common denominator is a surface chemistry based on a gold substrate with a self-assembled monolayer (SAM) of functionalized alkanethiolates. READ MORE

  4. 2. Surface characterization and manipulation of polyampholytic hydrogel coatings

    Author : Feng-I Tai; Thomas Ederth; Bo Liedberg; Lei Ye; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrogels; antifouling; charge-balanced material; polyampholytes; force measurements; polymer swelling; protein adsorption; patterning; plasmonics;

    Abstract : This thesis is dedicated to building up fundamental knowledge about polyampholytic hydrogels, which are developed in our group for anti-fouling purposes. Charge-balanced polymers, where positive and negative charges balance each other, have emerged as interesting candidates for many applications in materials science. READ MORE

  5. 3. Nanometer Scale Protein Templates for Bionanotechnology Applications

    Author : Jonas Rundqvist; David B. Haviland; Michael Grunze; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanotechnology; bionanotechnology; nanobiotechnology; electron beam lithography; EBL; poly ethylene glycol ; PEG; self-assembled monolayer; SAM; self-immobilization; protein pattern; Physics; Fysik;

    Abstract : Nanofabrication techniques were used to manufacture nanometer scale protein templates. The fabrication approach employs electron beam lithography (EBL) patterning on poly(ethylene glycol) (PEG) thiol (CH3O(CH2CH2O)17NHCO(CH2)2SH) self-assembled monolayers (SAM) on Au. READ MORE

  6. 4. Characterization of New Players in Planar Polarity Establishment in Arabidopsis

    Author : Stefano Pietra; Markus Grebe; Niko Geldner; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SABRE; planar polarity; CLASP; cell division orientation; microtubule cytoskeleton; actin; AIP1; patterning; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Abstract : Coordinated polarity and differentiation of cells in the plane of a tissue layer are essential to the development of multicellular organisms. Arabidopsis thaliana root hairs and trichomes provide model systems to study the pathways that control planar polarity and cell fate specification in plants. READ MORE

  7. 5. Orientation and Conformation of Single Macromolecules on Unmodified and Functionalized Surfaces

    Author : Magnus Bergkvist; David Cullen; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Atomic Force Microscopy; protein orientation; protein adsorption; surface derivatization; Bioteknik; Bioengineering; Bioteknik; Surface Biotechnology; ytbioteknik;

    Abstract : In this thesis methods for investigation of orientation and conformation of individual macromolecules on surfaces are presented as well as novel methods for functionalization of silicon chips with the possibility to get an ordered immobilization of antibodies. Two novel methods are presented which makes it possible to investigate the orientation of individual macromolecules on different kinds of surfaces with AFM. READ MORE
