    Sammanfattning : The overall purpose of this thesis was to reduce brain tissue responses around implanted microelectrodes using a pharmacological strategy. One of the main aims was to develop and evaluate drug delivery systems that allow local administration of anti-inflammatory pharmaceutics. LÄS MER

  5. 14. Integration and Fabrication Techniques for 3D Micro- and Nanodevices

    Författare :Andreas C. Fischer; Frank Niklaus; Karl F. Böhringer; KTH; []
    Nyckelord :Microelectromechanical systems; MEMS; Nanoelectromechanical systems; NEMS; silicon; wafer-level; chip-level; through silicon via; TSV; packaging; 3D packaging; vacuum packaging; liquid encapsulation; integration; heterogeneous integration; wafer bonding; microactuators; shape memory alloy; SMA; wire bonding; magnetic assembly; self-assembly; 3D; 3D printing; focused ion beam; FIB;

    Sammanfattning : The development of micro and nano-electromechanical systems (MEMS and NEMS) with entirely new or improved functionalities is typically based on novel or improved designs, materials and fabrication methods. However, today’s micro- and nano-fabrication is restrained by manufacturing paradigms that have been established by the integrated circuit (IC) industry over the past few decades. LÄS MER

  7. 15. On the Bone Tissue Response to Surface Chemistry Modifications of Titanium Implants

    Författare :Byung-Soo Kang; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osseointegrated titanium implants; Magnesium and Calcium Incorporated Bioactive Titanium Oxide; Metal Plasma Immersion Ion Implantation and Deposition; Micro Arc Oxidation; Clinical Implants; In Vivo Bone Response;

    Sammanfattning : Background: Surface properties of titanium implants play an important role in osseointegration. From 1990, a lot of engineering techniques have been applied to dental implant productions for improving their clinical performance by changing surface properties. LÄS MER
