    Abstract : Gasfasympning är en del i den moderna strategin för optimering av den molekylära designen av biomaterial. Kovalent ytmodifiering med hydrofila vinylmonomerer och koppling med bioaktiva grupper används för att öka biokompatibiliteten och bioaktiviteten hos biomaterialen.. READ MORE

  4. 2. Mass-Transport through Interfaces

    Author : Sofie Gårdebjer; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; poly 3-hydroxybutyrate ; permeability; diffusion cells; poly lactide-co-glycolide acid ; mass-transport; polyethylene; poly lactic acid ; ethylene acrylic acid; interfaces; cellulose;

    Abstract : Many of the products in our daily life consist of layered structures, where packaging materials and wound care products can be mentioned as examples. These structures often consist of different kind of polymeric materials and between these materials interfaces are formed. READ MORE

  5. 3. Polyelectrolytes and Polycomplexes in Biotechnology

    Author : Maria Dainiak; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; expanded bed adsorption.; affinity precipitation; Fab fragments; monoclonal antibodies; glyceraldehyde-3-phosphate dehydrogenase; misfolded protein; chaperone; poly N-ethyl-4-vinylpyridinium bromide ; poly methacrylic acid ; poly acrylic acid ; Key words: polyelectrolyte; polyelectrolyte complexes; Biotechnology; Bioteknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : Polyelectrolytes and polyelectrolyte complexes (PECs) are characterized by many useful properties that endow them with high potential in different areas of biotechnology. This thesis describes the development and analyses of some new systems and methods utilizing poly(acrylic acid) (PAA), poly(methacrylic acid) (PMA), poly (N-ethyl-4-vinylpyridinium bromide) (PEVP) and PMA-PEVP complexes.

  6. 4. Steric Stabilization of Polylactide particles achieved by Covalent 'grafting-from' with Hydrophilic Polymers

    Author : Robertus Wahyu Nayan Nugroho; Ann-Christine Albertsson; Karin Odelius; Anders Höglund; Mark Rutland; Martina Janstål; KTH; []
    Keywords : Steric stabilization; AFM; hydrophilicity; surface modification; poly lactide ; acrylamide; acrylic acid; maleic anhydride;

    Abstract : Despite numerous advantages of using particles in a wide range of applications, they have one drawback that is their tendency to agglomerate. One way to overcome this problem is to sterically  stabilize the particles by introducing polymeric  chains covalently attached to the surface. READ MORE

  7. 5. Development of an adductomic approach to identify electrophiles in vivo through their hemoglobin adducts

    Author : Henrik Carlsson; Margareta Törnqvist; Gunnar Boysen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Adductomics; Hemoglobin adducts; LC MS MS; Ethyl vinyl ketone; Glyoxal; Methylglyoxal; Acrylic acid; 1-Octen-3-one; Environmental Chemistry; miljökemi;

    Abstract : Humans are exposed to electrophilically reactive compounds, both formed endogenously and from exogenous exposure. Such compounds could react and form stable reaction products, adducts, at nucleophilic sites in proteins and DNA. READ MORE
