  2. 21. Development of Nanoimprint Lithography for Applications in Electronics, Photonics and Life-sciences

    Author : Patrick Carlberg; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mikroelektronik; Microelectronics; Teknik; ballistic; Technological sciences; Fysik; Physics; nanowire; TBJ; cantilever; IDA electrode; sensors; life-science; lift-off; patterning media; anti-sticking; mold; stamp; process development; thermal imprint; nanoimprint lithography; Biotechnology; Bioteknik; nanotechnology; polymer; nanostructure;

    Abstract : This thesis describes different aspects of nanotechnology manufacturing with nanoimprint lithography (NIL), a relatively new nanofabrication tool capable of high resolution and high throughput. Surface structure creation with NIL is based on mechanical deformation of the patterning material. READ MORE

  4. 22. Engineering tissue – Bacterial cellulose as a potential biomaterial

    Author : Maricris Esguerra; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bacterial cellulose Biocompatibility Blood vessels Non-neuronal cholinergic system Smooth muscle cells Tissue engineering;

    Abstract : Cardiovascular diseases are still the predominant cause of death among the adult population in the Western world. Diseases such as myocardial infarction and stroke are caused by occluded blood vessels, as a result of atherosclerosis. READ MORE

  5. 23. On healing after periapical surgery and different retrograde root-filling materials. A clinical and histological study

    Author : Dan-Åke Wälivaara; Göteborgs universitet; []
    Keywords : periapical surgery; ultrasonic preparation; IRM; thermoplasticized gutta-percha; Super-EBA; mineral trioxide aggregate; root-filling status; lesion size; lesion type;

    Abstract : Aims: The outcome from conventional endodontic therapy does not always result in a healing of the periapical area, thus leaving a remaining lesion with or without symptoms. The primary treatment alternative is a revision of the orthograde root-filling if applicable. A second treatment alternative might be a periapical surgery procedure. READ MORE

  6. 24. Thiol-Ene/Yne Adhesives for Tissue Fixation

    Author : Viktor Granskog; Michael Malkoch; Philip Messersmith; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The utilization of adhesives in surgery has not reached its full potential and research in the field is encouraged by the surgeons’ desire for improved alternatives to today’s tissue fixation strategies. Here, adhesive resins based on thiol-ene coupling (TEC) chemistry or thiol-yne coupling (TYC) chemistry are exploited to develop tissue adhesives that cure fast and on-demand via photoinitiation.

  7. 25. Interaction between biomaterials and innate immunity with clinical implications

    Author : Shan Huang; Kristina Nilsson Ekdahl; Charlotte Dahle; Linnéuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Complement system; contact system; blood; biomaterials; biocompatibility; in vitro screening; iC3; dialysis;

    Abstract : Today there is an increasing clinical demand and expectation of patients for biomaterials, which underscores the importance of discovering the correlations between biomaterials and biological systems, especially blood. When an artificial material makes contact with blood, the first event is a rapid adsorption of plasma protein on the material surface, on top of which the innate immune system is triggered, with potentially detrimental consequences.
