  1. 1. Development of Microfluidic 3D Cell Culture with a Nanocellulose-Based Scaffold for Spheroid Formation as a Potential Tool for Drug Screening

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Sara Payande; [2022]
    Keywords : 3D cell culture; Scaffold; Microfluidics; Layer-by-Layer; Cellulose Nanofibrils; Spheroids; HepG2; 3D cellodling; Matris; Mikrofluidik; Layer-by-Layer; Cellulosa Nanofibriller; Sfäroider; HepG2;

    Abstract : Abstract  Lack of clinical relevance is assumed to be the main reason behind the high failure rate of medical drugs in the very initial phases of clinical trials. Clinical relevance is difficult to achieve with current tools as they lack the biological and physiological cues found in vivo. READ MORE

  3. 2. Cellulose nanofibril-based Layer-by-Layer system for immuno-capture of circulating tumor cells in microfluidic devices

    University essay from KTH/Proteinvetenskap

    Author : Ekeram Lahchaichi; [2021]
    Keywords : Layer-by-layer; Thermodynamic equilibrium; Microfluidics; Cellulose nanofibrils; Cell capture; Point-of-care diagnostics; Layer-by-layer teknik; Termodynamisk jämvikt; Mikrofluidik; Cellulosa nanofibriller; Cellisolering; Point-of-care diagnostik;

    Abstract : År 2020 listade Världshälsoorganisationen (WHO) cancer som den globalt ledande dödsorsaken med över 10 miljoner dödsfall årligen. Av dessa 10 miljoner fall förekommer nästan 70% i låg- till medelinkomstländer - en siffra som på grund av den låga prioriteringen av cancerbehandling- och diagnostik förväntas öka till 85% redan år 2030.

  4. 3. Polymer Directed Engineering of Novel Cellulose Network

    University essay from KTH/Fiber- och polymerteknologi

    Author : Christel Gradin; Adina Landström; Julia Szecsödy; [2021]
    Keywords : Hydrogel; Carboxylated CNF; TEMPO-oxidation; bis-MPA ammonium dendrimer; Polymer salt bridge; Rheology;

    Abstract : This study investigated a CNF/dendrimer hydrogel and how different concentrations of the carboxylated CNF and bis-MPA ammonium dendrimer affected the hydrogels’ rheological properties. A third generation bis-MPA ammonium dendrimer was diffused into a dispersion of carboxylated cellulose nanofibrils. READ MORE

  5. 4. Transparent paper: Evaluation of chemical modification routes to achieve self-fibrillating fibres

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Paulina Sandberg Birgersson; [2020]
    Keywords : Transparent paper; nanopaper; nanocellulose; chemical modification of cellulose; cellulose nanofibrils CNF ; Transparent papper; nanopaper; nanocellulosa; kemisk modifiering av cellulosa; cellulosa nanofibriller CNF ; nanopapper;

    Abstract : Transparenta papper tillverkade av cellulosa nanofibriller (CNF), visar stor potential att kunna ersätta petroleumbaserade plaster inom många användningsområden, till exempel för mat- och varuförpackningar. CNF, även känt som nanocellulosa, kombinerar viktiga cellulosaegenskaper, med unika egenskaper hos nanomaterial. READ MORE

  6. 5. Optical Coherence Tomography measurements of biofibril dispersions in flow-focusing

    University essay from KTH/Mekanik

    Author : Cecilia Rydefalk; [2019]
    Keywords : ;

    Abstract : Microfluidic spinning techniques have been used as a successful assembly process for biofibrils dispersed in a fluid. The dispersion flows through a microchannel and is focused by a sheath flow. In this way the topology and velocity of the dispersion in the core can be manipulated. READ MORE
