2. 21. Detection of Lipids and Proteins on Biological Surfaces using Imaging Mass Spectrometry

   Author : Louise M Carlred; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ToF-SIMS; GM1; cholesterol; Amyloid-β; phospholipids; Imaging Mass Spectrometry; Alzheimer’s disease; sulfatides; QCM-D; MALDI;

   Abstract : Time-of-flight secondary ion mass spectrometry (ToF-SIMS) is a technique that can be used for imaging the spatial distribution of many different molecules at the same time. It is very sensitive for detection of small biomolecules, such as lipids, whereas larger biomolecules, such as peptides and proteins, cannot be detected as intact entities due to fragmentation.

4. 22. Molecular Interactions in Thin Films of Biopolymers, Colloids and Synthetic Polyelectrolytes

   Author : Johansson Erik; Lars Wågberg; Andreas Fery; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polyelectrolyte multilayers; Layer-by-Layer assembly; Adhesion; Adsorption; Young s modulus; Mechanical buckling; AFM; JKR; SPAR; QCM-D; SIEBIMM; PAH; PAA; Starch; NFC; Nanocellulose;

   Abstract : The development of the layer-by-layer (LbL) technique has turned out to be an efficient way to physically modify the surface properties of different materials, for example to improve the adhesive interactions between fibers in paper. The main objective of the work described in this thesis was to obtain fundamental data concerning the adhesive properties of wood biopolymers and LbL films, including the mechanical properties of the thin films, in order to shed light on the molecular mechanisms responsible for the adhesion between these materials.

5. 23. Synergies in Biolubrication

   Author : Akanksha Raj; Andra Dedinaite; Imre Varga; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biolubrication; Synergies; Adsorption; Surface Force; Friction; Load Bearing Capacity; Self Healing; Phospholipids; DPPC; Hyaluronan; COMP; Lubricin; QCM-D; AFM; XRR.; Kemi; Chemistry;

   Abstract : The objective of this thesis was to advance understanding in the field of biolubrication, finding inspiration from the human synovial joints. This was addressed by investigating the association of key biolubricants and the resulting lubrication performance. READ MORE

6. 24. Nanoplasmonic sensing: from biology to catalysis

   Author : Elin Maria Kristina Larsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; hole-mask colloidal lithography; colloidal lithography; nanoring; QCM-D.; quartz crystal microbalance; nanodisk; catalysis; LSPR; Localized Surface Plasmon Resonance; biosensing;

   Abstract : Our continuously increasing concerns about our health, safety, environment and climate has brought about a need for more sophisticated sensors that enable reliable detection of a variety of events. Sensors are today omnipresent in daily life. READ MORE

7. 25. Studies of Glycosaminoglycan Interactions - Surface Immobilization Strategies and Biosensing Applications

   Author : Noomi Altgärde; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; glycosaminoglycans; interaction studies; growth factor; QCM-D; virus glycoprotein; SPR; surface immobilization;

   Abstract : Many important biological functions of glycosaminoglycans (GAGs) have been highlighted in research literature during recent years. GAGs often serve as function-bearing structural elements in the extracellular matrix (ECM), but are also constituents of the cell membrane. GAGs take part in various biological mechanisms, e.g. READ MORE
