  1. 1. The application of microfluidic devices and multifunctional fibers in cancer diagnostics

    Författare :Tharagan Kumar; Aman Russom; Fredrik Laurell; Gustaf Mårtensson; Johan Kreuger; KTH; []
    Nyckelord :Circulating tumor cells; microfluidics; point of care; inertial microfluidics; elasto inertial microfluidics; nano-cellulose; layer-by-layer; optical fiber; microflow cytometer.; Bioteknologi; Biotechnology;

    Sammanfattning : Efficient separation and detection of rare cells in a mixed population is important in many biomedical applications. For instance, isolating and detecting circulating tumor cells (CTCs) from whole blood samples could allow for early cancer diagnosis and prognosis during treatment. LÄS MER

  3. 2. Mille-feuille Filter : A Non-woven Nano-cellulose Based Virus Removal Filter for Bioprocessing

    Författare :Simon Gustafsson; Albert Mihranyan; Jonas Lindh; Kurt Brorson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; virus filtration; mille-feuille; downstream; nanocellulose; protein throughput; protein recovery; LRV; MVM; Cladophora; non-woven filter;

    Sammanfattning : Virus removal filters, produced from synthetic surface-modified polymers or regenerated cellulose by phase inversion, are vital to the production of therapeutic proteins such as monoclonal antibodies and plasma proteins. Use of these filters is also one of the most expensive purification steps in the downstream processing of proteins due to high sales price and being limited to a single use. LÄS MER

  4. 3. Water-assisted mixing and compression moulding of ethylene-acrylic acid copolymer reinforced with nano-cellulose

    Författare :Abhijit Venkatesh; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal stability; cellulose nanocrystals; azetidinium; amphiphilic co-polymer; Nanocellulose; rheology; cellulose nanofibrils; water-assisted mixing.;

    Sammanfattning : The concerns regarding aspects of global warming, depleting oil resources, accumulation of plastics in landfills has served as motivation to move towards utilizing sustainable and renewable resources to fulfil our needs. In the present work, the reinforcing capabilities of cellulose nanofibrils (CNF) and modified/unmodified cellulose nanocrystals (CNC) based composites prepared through water-assisted mixing, drying and compression moulding was explored.

  5. 4. Biomedical Applications of Bacterial Cellulose Fermentation, Morphology and Surface Properties

    Författare :Aase Katarina Bodin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocompatibility; xyloglucan epitopes; mechanical properties; cell adhesion; tubular fermentation; morphology; Bacterial cellulose; surface properties; meniscus mold; crystal formation.; ozonation; adsorption;

    Sammanfattning : Because average life expectancy has increased and peoples lifestyles have changed, degenerative diseases have become a critical issue. The demand for biomedical materials to replace or improve major body systems (skeletal, circulatory and nervous, etc.) will increase as people strive to maintain good quality of life. LÄS MER
