  1. 16. Silk's sweet spot: untangling the requirements for artificial silk extrusion using a biomimetic approach

    University essay from Lunds universitet/Tillämpad biokemi

    Author : Rodrigo Sanches Pires; [2019]
    Keywords : silk fibroin; injectability; extrusion; hydrogels; soft matter mechanics; biomimetic progressive acidification; silk self-assembly; thioflavin t; physical chemistry; biofabrication; spectroscopy; silk spinning; applied biochemistry; tillämpad biokemi; Technology and Engineering;

    Abstract : Up to this date, only a few silk hydrogels were reported to be injectable. Of these, none are truly biomimetic, and are instead comprised of blends with limited amounts of silk. Hence, no truly silk-based hydrogels exist as of today. READ MORE

  4. 18. Optimization of Acidic Degradation of Hyaluronic Acid using Design of Experiments

    University essay from Linköpings universitet/Teknisk biologi

    Author : Emma Sandqvist Wedin; [2019]
    Keywords : Hyaluronic Acid; Molecular Weight; Acidic Degradation; Heterogeneous Degradation; Robustness Testing; Degradation Constant; Design of Experiments; Degradation; DoE;

    Abstract : Hyaluronic acid (HA) is an unbranched polysaccharide consisting of the repeating disaccharide unit β(1→4)-GlcA-β(1→3)-GlcNAc and is a naturally occurring biopolymer in bacteria and vertebras. HA is predominantly found in the extracellular matrix (ECM) and the in vivo function of HA can vary depending on molecular weight (Mw) for instance high Mw HA is reported to be anti-angiogenic while low Mw HA induces angiogenesis.

  5. 19. Endeavors toward Novel Cochlear Implants from Stretchable Printed Circuit Board Technology

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Rickard Viik; [2019]
    Keywords : novel; cochlear; implant; electrode array; electrode; stretchable; soft; electronics; pdms; polydimethylsiloxane; liquid; alloy; galinstan; hearing aid;

    Abstract : Profound sensorineural hearing loss is at the present time a major worldwide health concern, affecting over 5% of the worlds' population. Through cochlear implants (CI), treatment of sensorineural hearing loss now offers the possibility to restore hearing function through electrical stimulation of auditory nerves. READ MORE

  6. 20. Analysis of hydrogels for immobilisation of hepatocytes (HepG2) in 3D cell culturing systems

    University essay from Linköpings universitet/Teknisk biologi

    Author : Elisabeth Westergren; [2018]
    Keywords : Hydrogel; Hepatocyte; Tuneable; PEG-peptide; 3D cell culture;

    Abstract : In pharmaceutical development cell cultures are used as in vitro models to evaluate the function of drug candidates. In such research it is vital to have models that resemble the in vivo environment to get reliable results. READ MORE
