2. 1. Nanostructured Artificial Biointerfaces

   Author : Hossein Agheli; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Colloidal Lithography; Electrostatic Self Assembly; Nanofabrication; Cell;

   Abstract : AbstractThe interactions occurring between biological systems and the surface of biomaterials hasbeen an area of strong research focus for a number of decades. There has been a realisation ofthe importance of macromolecular interactions and a consequent need to understandbiointerfacial events at the nanometer length-scale. READ MORE

4. 2. Functionalized Biomaterial Surfaces by Micro- and Nanofabrication

   Author : Sarunas Petronis; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanofabrication; surface characterization; surface topography; surface chemical composition; marine biofouling; force-sensing substrates; microfabrication; surface-enhanced Raman spectroscopy; cell-surface interaction; biointerfaces; biomaterials;

   Abstract : In the field of biomaterials, well-defined nano- and micropatterns or features at material surfaces can serve both as models for investigating material-biosystem interactions and as functional features for inducing, hindering or measuring specific bioreactions or biologic responses. Important bioreactions include protein adsorption and conformation, cell attachment and function, and adhesion and function of organized tissues or whole organisms. READ MORE

5. 3. Connecting sialic acid expression to cancer cell characteristics : Novel tools for detection, imaging, and analysis

   Author : Louise Sternbæk; Anette Gjörloff Wingren; Kersti Alm; Birgit Janicke; Håkan Eriksson; Magnus Abrahamson; Malmö universitet; []
   Keywords : Molecularly imprinted polymers; digital holographic cytometry; cancer; cytotoxicity; inflammation; sialic acid; Health and society; Hälsa och samhälle;

   Abstract : Sialic acid (SA) plays a crucial role in many biological processes. Cell surface SA expression is usually analyzed with antibodies or lectins; however, they are costly and with poor stability. READ MORE

6. 4. Surface Modifications for Biointerfaces - Supported Lipid Bilayers and some Aspects of Microcontact Printing

   Author : Karin Glasmästar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; QCM-D; PDMS; cell attachment; supported lipid bilayer; microcontact printing; SPR; ToF-SIMS; protein adsorption; formation kinetics; XPS;

   Abstract : Biointerfaces engage several disciplines: physics, materials science, chemistry, biology and medicine. They are found on the surfaces of implants, tubes and tanks in the food industry or on the hull of a boat. In this work, model surfaces aimed for contact with biological systems were studied.

7. 5. Nanoscale Osseointegration : Characterization of Biomaterials and their Interfaces with Electron Tomography

   Author : Kathryn Grandfield; Håkan Engqvist; Peter Thomsen; Anders Palmquist; Alexandra Porter; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electron tomography; transmission electron microscopy; hydroxyapatite; titanium; titania; bone; implant; osseointegration; interface; mesoporous; Materialvetenskap; Materials Science;

   Abstract : Bone response is one of the key determining factors in the overall success of biomaterials intended for bone regeneration and osseointegration. Understanding the formation of bone at an implant surface may lead to the improved design of biomaterials for the future. READ MORE
