1. 6. Lipid-Based Surface Modifications: towards the Development of Membrane-Protein Arrays

   Författare :Indriati Pfeiffer; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DNA-array; cholesterol-DNA; EIS; membrane proteins; lipid vesicles; QCM-D; supported lipid bilayer;

   Sammanfattning : Mimics of the natural cell membrane, such as lipid vesicles and supported lipid membranes, have gained significant attention in recent years. This is primarily due to their ability to provide scientists with a model system allowing a large arsenal of scientific tools to be used in studies of biological reactions that are naturally controlled by the cell membrane and its components.

   Sammanfattning : In the past decade there has been increasing interest in exploring the use of nanocellulose in medicine. However, the influence of the physicochemical properties of nanocellulose on the material´s biocompatibility has not been fully investigated. LÄS MER

5. 9. Interactions Between Localized Surface Plasmons and Molecular Resonances

   Författare :Gülis Zengin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; single particles; J-aggregates; Rhodamine 6G; Localized surface plasmon resonance; strong coupling; surface-enhanced absorption;

   Sammanfattning : Molecular plasmonics is the study of interactions between plasmonic nanostructures and molecules. It has been basis for fundamental understanding of light-matter interactions and development of many technological applications, such as biological and chemical sensing, plasmon-enhanced spectroscopies, optical switches, and plasmon-enhanced energy harvesting.

7. 10. On the influence of micro-and macroscopic surface modifications on bone integration of titanium implants

   Författare :Patricia Miranda Burgos; Göteborgs universitet; []
   Nyckelord :titanium; dental implants; surface modification; bone tissue; biomechanics; BMP-2;

   Sammanfattning : Background: Osseointegrated titanium implants are routinely used in clinical denstistry as anchorage units for dental prostheses. Although the overall clinical results are good, there are clinical situations when an optimized implant healing is desirable, for instance in order to shorten healing periods and to allow immediate loading.
