  2. 1. Towards Energy-Efficient Drinking Water Production using Biomimicry

    Author : Simon Isaksson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Filter; Membrane Protein; Supported Lipid Bilayer; Drinking Water; Water Treatment; Silica; Aquaporin; Liposome; Biomimicry;

    Abstract : Water is a prerequisite for life and we therefore need pure drinking water to survive. Yet there are more than half a billion people that do not have access to pure drinking water. Water treatment can be performed in many different ways, one of the most commonly used being filtration. READ MORE

  4. 2. Human iPSC-based models of theCNS: attaining cellular biofidelitythrough conventional and advancedculture systems

    Author : Dimitrios Voulgaris; Anna Herland; Susanna Narkhilakhi; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; neural stem cells; astrocytes; iPSC; hiAstrocytes; microphysiological systems; BBB; Bioteknologi; Biotechnology;

    Abstract : Brain development is a highly orchestrated process that entails changes in microenvironmental cues and growth factor gradients, which set the tempo for proper development of the rudimentary structures of the brain and the generation of neurons,astrocytes, and oligodendrocytes. Another intricate feature of the brain is the bloodbrain barrier (BBB). READ MORE

  5. 3. An Investigation of Peroxidase Activity in Biomimetic and Biological Systems

    Author : Ekaterina Ryabova; Kemiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metabolism; Metabolism; enzymologi; Proteiner; enzymology; Proteins; hemoglobin; catalysis; peptide; peroxidase; protoporphyrin IX; Biokemi; Biochemistry;

    Abstract : In order to create a heme environment which permits biomimicry of heme-containing plant peroxidases and investigate the role played by the vinyl side chains of the porphyrin ring on the stability and, possibly, catalytic activity of model compounds, a number of new synthetic microperoxidases -– hemin-6(7)-gly-his methyl ester (HGH) and hemin-6(7)-gly-gly-his methyl ester (HGGH) and hemin-6,7-bis(gly-gly-his methyl ester) (H2GGH) as well as mesohemin-6(7)-gly-gly-his methyl ester (MGGH) and deuterohemin-6(7)-gly-gly-his methyl ester (DGGH) have been prepared by condensation of a peptide residue with the propionic side chains of hemin, mesohemin and deuterohemin, respectively. Reactivity studies towards different organic and inorganic substrates showed that not only five- but also six-coordinate hemin peptide complexes catalyze the oxidation of substrates by H2O2.

  6. 4. Biomimetic spider silk and bioactive hydrogels formed by engineered recombinant spider silk proteins

    Author : Tina Arndt; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Spider silk is a unique material and its properties have fascinated material scientists, biologists and physicians for decades. Spider silk display one of the highest toughness found among fibers in nature, is used by spiders for web-spinning, prey-wrapping and cocoon building, while scientists have explored its biomaterials properties for multiple purposes.
