2. 6. Novel Microfluidic Devices Based on a Thermally Responsive PDMS Composite

   Author : Björn Samel; Göran Stemme; Jörg Kutter; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEMS; microsystem technology; micro total analysis system; lab-on-a-chip; microfluidics; composite actuator; expandable microspheres; PDMS; poly dimethylsiloxane; disposable; wafer bonding; adhesive bonding; PDMS bonding; adhesive PDMS bonding; selective PDMS bonding; microcontact printing; Electrical engineering; Elektroteknik;

   Abstract : The field of micro total analysis systems (μTAS) aims at developments toward miniaturized and fully integrated lab-on-a-chip systems for applications, such as drug screening, drug delivery, cellular assays, protein analysis, genomic analysis and handheld point-of-care diagnostics. Such systems offer to dramatically reduce liquid sample and reagent quantities, increase sensitivity as well as speed of analysis and facilitate portable systems via the integration of components such as pumps, valves, mixers, separation units, reactors and detectors.

4. 7. Composite Regenerative Scaffolds

   Author : Elle Edin; Jöns Hilborn; May Griffith; Alicia El Haj; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nerve; neurite; regeneration; PEDOT; PEDOT:Tosylate; electrostimulation; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

   Abstract : Regenerative medicine and tissue engineering solutions of heavily innervated tissues are at this point lacklustre. This thesis expands our knowledge of appropriate acellular scaffolds for tissue repair in general and nerve regeneration in particular. READ MORE

5. 8. Functional Nanocellulose–Tannin Materials Inspired by Nature and Traditional Processes

   Author : Konstantin Kriechbaum; Lennart Bergström; Alain Dufresne; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cellulose; Nanofibrils; Tannin; Biobased; Films; Foams; Moisture resistance; Energy efficiency; Materials Chemistry; materialkemi;

   Abstract : Renewable and biodegradable alternatives to fossil-based materials are essential as concerns over depleting finite resources and the pollution of our ecosystems are growing. Abundant, highly anisotropic, and mechanically strong cellulose nanofibrils (CNF) are attractive building blocks for the fabrication of high-performance biobased materials that can compete with their conventional fossil-based counterparts.

6. 9. Spatially Controlled Covalent Immobilization of Biomolecules on Silicon Surfaces

   Author : Elisabeth Pavlovic; Sven Oscarsson; Marcus Textor; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; silicon oxide; electrooxidation; sulfur; nanotechnology; self-assembled monolayers; atomic force microscopy; electron spectroscopy for chemical analysis; biomolecules; covalent immobilization; reversibility; Bioteknik; Bioengineering; Bioteknik;

   Abstract : The work described in this thesis aims to achieving surface patterning through chemical activation of thiolated silicon oxide surfaces, resulting in a spatially controlled covalent immobilization of biomolecules with high resolution.Existing chemical methods to immobilize molecules on surfaces do not reach below the micrometer scale while the ones allowing for spatial control mostly lead to non-covalent adsorption of molecules on surfaces, or require several successive chemical reactions to obtain the final covalent immobilization.

7. 10. Nanoparticles : Engineering, Assembly, and Biomedical Applications

   Author : Do Kyung Kim; KTH; []
   Keywords : nanoparticle; superparamagnetism; self assembly; ;

   Abstract : This thesis deals with novel aspects through Nanotechnologyof"bottom-up"and"top-down"strategies in combination with Biotechnology as aninterdisciplinary study. The feasibility of chemically tailoredsuperparamagnetic iron oxide nanoparticles (SPION) forin-vivobiomedical applications has beendemonstrated. READ MORE
