Competitive ligand exchange of crosslinking ions for ionotropic hydrogel formation.
Bassett, David; Håti, Armend Gazmeno; Melø, Thor Bernt; Stokke, Bjørn Torger; Sikorski, Pawel (Journal article; Peer reviewed, 2016)Currently there are limitations to gelation strategies to form ionically crosslinked hydrogels, derived in particular from a lack of control over the release kinetics of crosslinking ions, which severely restrict applications. ... -
Direct Determination of Chitosan–Mucin Interactions Using a Single-Molecule Strategy: Comparison to Alginate–Mucin Interactions
Haugstad, Kristin Elisabeth; Håti, Armend Gazmeno; Nordgård, Catherine Taylor; Adl, Patricia S.; Maurstad, Gjertrud; Sletmoen, Marit; Draget, Kurt Ingar; Dias, Rita de Sousa; Stokke, Bjørn Torger (Journal article; Peer reviewed, 2015)Aqueous chitosan possesses attractive interaction capacities with various molecular groups that can be involved in hydrogen bonds and electrostatic and hydrophobic interactions. In the present paper, we report on the direct ... -
Energy Landscape of Alginate-Epimerase Interactions Assessed by Optical Tweezers and Atomic Force Microscopy
Håti, Armend Gazmeno; Aachmann, Finn Lillelund; Stokke, Bjørn Torger; Skjåk-Bræk, Gudmund; Sletmoen, Marit (Journal article, 2015)Mannuronan C-5 epimerases are a family of enzymes that catalyze epimerization of alginates at the polymer level. This group of enzymes thus enables the tailor-making of various alginate residue sequences to attain various ... -
Microarrays for the study of compartmentalized microorganisms in alginate microbeads and (W/O/W) double emulsions
Håti, Armend Gazmeno; Arnfinnsdottir, Nina Bjørk; Østevold, Camilla; Sletmoen, Marit; Etienne, Gianluca; amstad, esther; Stokke, Bjørn Torger (Journal article; Peer reviewed, 2016)Understanding of cells has mainly been achieved through analysis of average properties of large cellular populations. The increased awareness of cellular heterogeneity in various biological systems, spans from single ... -
Microfluidic Fabrication of Mineralized Alginate Hydrogel Fibers
Mandaric, Stefan (Master thesis, 2015)Alginates are a family of naturally occurring polysaccharides that form gels in the presence of Ca2+-ions at physiological conditions. Calcium phosphate mineralized alginates have previously been investigated as a synthetic ... -
Nano- and microscale control of alginate interactions and assembly
Håti, Armend Gazmeno (Doctoral theses at NTNU;2016:259, Doctoral thesis, 2016)Hydrogels are materials primarily comprised of water and are extensively applied to mimic the extracellular matrix surrounding the cells in our body. Alginate, a naturally derived biopolymer shows great promise in this ... -
Single molecule dynamic force spectroscopy of alginate-epimerase interactions using optical tweezers
Håti, Armend Gazmeno (Master thesis, 2012)Alginate, a naturally occurring polysaccharide found in various cell lines, is synthesized as a homopolymer polymannuronic acid also known as mannuronan or PolyM. Conversion of the polymers subunits β-D-mannuronic acid (M) ... -
Versatile, cell and chip friendly method to gel alginate in microfluidic devices
Håti, Armend Gazmeno; Bassett, David; Ribe, Jonas Myren; Sikorski, Pawel; Weitz, David A.; Stokke, Bjørn Torger (Journal article, 2016)Alginate is used extensively in microfluidic devices to produce discrete beads or fibres at the microscale. Such structures may be used to encapsulate sensitive cargoes such as cells and biomolecules. On chip gelation of ...
