  1. 1. Nanoscale Reaction Systems

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

    Sammanfattning : 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.

  3. 3. Nano-porous Alumina, a Potential Bone Implant Coating

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

    Sammanfattning : 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. LÄS MER

  4. 4. Development and Validation of HPLC Methods for Analytical and Preparative Purposes

    Författare :Johan Lindholm; Torgny Fornstedt; Karin Caldwell; Karl-Gustaf Wahlund; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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;

    Sammanfattning : 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. LÄS MER

  5. 5. Development of Methods for Phase System Characterization in Liquid Chromatography

    Författare :Jörgen Samuelsson; Torgny Fornstedt; Karin Caldwell; Attila Felinger; Uppsala universitet; []
    Nyckelord :Analytical chemistry; Liquid chromatography; Adsorption isotherms; Adsorption energy distribution; Tracer pulse method; Elution by characteristic points; Peak deformation; Validation; Hybrid column material; Alkaline separation; Injection-profiles; Analytisk kemi;

    Sammanfattning : The aim of this thesis is first and foremost to improve the fundamental knowledge of nonlinear and preparative separation theory by focusing on some of the remaining “white spots” on the theoretical chromatographic map. Secondly, the acquired knowledge is used to develop, validate and execute new methods for phase characterization in liquid chromatography. LÄS MER
