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

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

    Sammanfattning : 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. LÄS MER

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

    Författare :Henrik Carlsson; Margareta Törnqvist; Gunnar Boysen; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
