  2. 1. Nanoscale Reaction Systems

    Author : Karin Fromell; Karin Caldwell; Francesco Dondi; Uppsala universitet; []
    Keywords : Life sciences and physical sciences; nanoparticles; Sedimentation Field-Flow Fractionation; bioaffinity; multilayered functionalization; protein attachment; diagnostics; bioluminescence; NATURVETENSKAP;

    Abstract : The work presented in this thesis describes the use of polystyrene nanoparticles as model surfaces for bioanalytical work. Nanoparticles constitute convenient platforms for the attachment of bioactive agents, and receptor coated particles offer high local concentration of binding sites for specific ligands with minimal steric hindrance.

  5. 3. Phosphorylated Monomolecular Layers : Design, Synthesis, Characterization and Application

    Author : Johan Ekeroth; Karin Caldwell; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis describes the design, synthesis and characterization of organo-phosphatemonomolecular layers, so called self-assembled monolayers, using the strategy of linking organosulfur substances to a gold surface. Moreover there is also a paper included, which describes the development of synthetic pathways to various phospholipids, for which I have developed an interest in later projects. READ MORE

  6. 4. Nano-porous Alumina, a Potential Bone Implant Coating

    Author : Marjam Karlsson; Karin Caldwell; Mats Boman; Matteo Santin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Nano-porous aluminium oxide; Biomaterial; Hard tissue implant; Surface topography; Osteoblast; Biocompatibility; Neutrophil; Inflammation; Kemi; Chemistry; Kemi;

    Abstract : This thesis describes a method of growing a highly adherent nano-porous alumina coating on titanium implant materials, a design which might be useful in hard tissue replacement. Alumina layers were formed by anodisation of aluminium, which had been deposited on titanium and titanium alloys by electron beam evaporation. READ MORE

  7. 5. Development and Validation of HPLC Methods for Analytical and Preparative Purposes

    Author : Johan Lindholm; Torgny Fornstedt; Karin Caldwell; Karl-Gustaf Wahlund; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; High performance liquid chromatography HPLC ; Analytical biotechnology; Sample preparation; Diode-array-detection DAD ; Mass spectrometry MS ; Validation; Preparative chromatography; Competitive isotherm parameters; Perturbation peak PP method; Kemi; Chemistry; Kemi;

    Abstract : This thesis concerns the development and validation of high performance liquid chromatography (HPLC) methods aimed for two industrially important areas: (i) analysis of biotechnological synthesis and (ii) determination of adsorption isotherm parameters. There is today a lack of detailed recommendations for analytical procedures in the field of biotechnological production of drugs. READ MORE
