2. 1. Interfacial Properties of Film Forming Proteins and their Layer-by-Layer Assembly with Nanoparticles

   Author : Olga Krivosheeva; Per Claesson; Thomas Arnebrant; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein adsorption; mussel adhesive protein; Mefp-1; hydrophobins; HFBI; HFBII; adsorption kinetics; layer-by-layer; stability; cross-linking; zeta-potential; dual polarization interferometry; quartz crystal microbalances;

   Abstract :  The aim of this thesis work was to investigate the interfacial properties of film forming proteins, stability of the layers created by them, and their interactions with nanoparticles. Mussel adhesive protein (Mefp-1) and hydrophobins (HFBI and HFBII) were the three main proteins used. READ MORE

5. 3. Multilayer Structures for Biomaterial Applications : Biomacromolecule-based Coatings

   Author : Tobias Halthur; Per M. Claesson; Bjørn Stokke; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; multilayer; layer-by-layer deposition; physical chemistry; surface chemistry; adsorption; ellipsometry; QCM-D; DPI; protein adsorption; polypeptides; biomaterials; biosurfaces; amelogenin; solid liquid interface; Surface and colloid chemistry; Yt- och kolloidkemi;

   Abstract : The cellular response to a biomaterial, such as a dental implant, is mainly governed by the surface properties, and can thus be altered by the introduction of a surface coating. In this thesis the buildup of a biomacromolecule-based coating formed by layerby-layer (LbL) deposition of the charged polypeptides poly(L-lysine) (PLL) and poly(L-glutamic acid) (PGA) has been studied.

6. 4. Dynamics of Enzymes at Interfaces : Lipase adsorption and mobility on solid surfaces

   Author : Andreas Sonesson; Hjalmar Brismar; Robert Tilton; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; biophysics; surface chemistry; diffusion; enzymes; lipases; adsorption; mobility; Physics; Fysik;

   Abstract : This thesis aimed to give more insight in the dynamics of enzymes at interfaces. The adsorption and mobility of adsorbed proteins can e.g. give a better understanding of structure-function properties of interfacially active enzymes. READ MORE

7. 5. Tailored layer-by-layer films of nanofibrillated cellulose

   Author : Erdem Karabulut; Lars Wågberg; Lennart Piculell; Eva Blomberg; KTH; []
   Keywords : layer-by-layer assembly; nanofibrillated cellulose; thin film; surface adsorption; polyelectrolytes;

   Abstract : The preparation of multifunctional films, coatings and membranes from natural, sustainable and low-cost raw materials has attracted considerable interest during the last decade. In this respect, cellulose-based products possess a great promise for research and industry due both to the availability of large amounts of material in nature and to the preparation of new classes of nano-sized and well-characterized building-blocks of cellulose from trees or annual plants.
