2. 1. Investigation of Incompatibility Reactions Caused by Biomaterials in Contact with Whole Blood Using a New in vitro Model

   Author : Jaan Hong; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; biomaterials; coagulation; complement; heparin; leukocytes; platelets; PVC; titanium; Onkologi; Oncology; Onkologi; Clinical Immunology; klinisk immunologi;

   Abstract : This thesis describes a new in vitro slide chamber model that makes it possible to conduct studies of molecular and cellular interactions between whole blood and biomaterials. The model proved to be a suitable tool for detection of cell and platelet binding to a biomaterial surface. READ MORE

4. 2. Effect of Surface Nanotopography on Blood-Biomaterial Interactions

   Author : Natalia Ferraz; Marjam Ott; Jaan Hong; Jan Carlsson; Tom Eirik Mollnes; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nanoporous alumina; nanotopography; biomaterial; platelets; complement system; macrophages; whole blood; inflammatory response; Chemistry; Kemi; Immunobiology; Immunbiologi; Immunologi; Immunology; Materialvetenskap; Materials Science;

   Abstract : Biologically inspired materials are being developed with the aim of improving the integration of medical implants and minimizing non-desirable host reactions. A promising strategy is the design of topographically patterned surfaces that resemble those found in the extracellular environment. READ MORE

5. 3. Electron beam melting: Impact of part surface properties on metal fatigue and bone ingrowth

   Author : Rebecca Klingvall Ek; Lars-Erik Rännar; Mikael Bäckström; Jaan Hong; Ola Harrysson; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing AM ; Electron Beam Melting EBM ; As-built surfaces; Bone Ingrowth; Metall Fatigue; Machined Surfaces; Hirtisation; Hot Isostatic Pressing HIP ;

   Abstract : AbstractThe aim of this thesis is to investigate aspects on how additive manufacturing (AM) contributes to functional bone implants with the use of the electron beam melting (EBM) technology. AM manufactures parts according to computer-aided design, and the EBM technology melts powder using an electron beam, which acts similar to a laser beam. READ MORE

6. 4. SURFACE PROPERTIES OF IMPLANTS MANUFACTURED USING ELECTRON BEAM MELTING

   Author : Rebecca Klingvall Ek; Lars-Erik Rännar; Mikael Bäckström; Jaan Hong; Felicia Suska; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electron beam melting; blood coagulation; bone ingrowth; surface roughness; process parameters;

   Abstract : This thesis summarizes the results concerning the manufacture of medical implants for bone replacement using electron beam melting (EBM) which is an additive manufacturing (AM) technology, and aims to satisfy the engineering needs for the medical functionality of manufacturing technology. This thesis has focused on some microscopic properties for surfaces and bone integration. READ MORE
