  2. 21. A tailored biocompatible neural interface for long term monitoring in neural networks

    Author : Per Köhler; Neuronano Research Center (NRC); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain-machine interfaces; neuroinflammation; somatosensory cortex; hyperalgesia; allodynia;

    Abstract : Neural interface electrodes that can record from neurons in the brain for long periods of time will be of great importance to unravel how the brain accomplishes its functions. However, current electrodes usually cause significant glia reactions and loss of neurons within the adjacent brain parenchyma. READ MORE

  4. 22. Chemical Modification of Nanostructured Wood for Functional Biocomposites

    Author : Shennan Wang; Qi Zhou; Gustav Nyström; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood; nanostructured materials; nanocellulose; delignification; oxidation; crosslinking; amination; MOFs; transparent film; hydrogel; aerogel; biocomposites; mechanical properties; thermochromic materials; CO2 capture; protein immobilization.; Biotechnology; Bioteknologi;

    Abstract : Recently emerged top-down processing concept has provided new insights into the chemical modification of wood at the nanoscale. Nanostructured wood with naturally aligned cellulose microfibrils, cell wall nanoporosity, and precisely tuned chemical composition has opened up numerous possibilities for advanced design of functional materials.

  5. 23. Modified Starches in aqueous and plastisol coating

    Author : Agneta Jansson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Starch; Polyvinyl alcohol; Water vapor barrier; Tensile properties; Rheology; Chemical Engineering; Kemiteknik;

    Abstract : The interest for coatings containing renewable materials has enlarged in the last decade. Materials from the nature are investigated like starch, cellulose derivatives, protein (gelatin), chitosane by many. In this study potato starch has been used. READ MORE

  6. 24. Decellularized liver extracellular matrix as a 3D scaffold for bioengineering applications

    Author : Vamakshi Khati; Aman Russom; Håkan Jönsson; Giulia Gaudenzi; Ana Teixeira; KTH; []

    Abstract : The increasing global burden of end-stage liver disease has increased the need for liver transplantation, the definitive cure. However, there is a huge discrepancy between the number of available organ donors and the number of patients waiting for transplantation, resulting in the deaths of a significant number of patients on the waiting list as only 10% of the global need for transplantation is met.

  7. 25. Studies of Mesenchymal Progenitor Cells and Tumour Growth, Integrins and Matrix Metalloproteinases

    Author : Lars Bryngelsson Ohlsson; Immunologi; []

    Abstract : In this thesis we characterize the effect of mesenchymal progenitor cells (MPCs) on tumour growth, and show that MPCs can have inhibitory effects on tumour development. We developed a method to subcutaneously transplant tumour cells, cultured in vitro in a pre-formed gelatin matrix, that made it possible to study the early phases of tumour development. READ MORE
