1. 1. Purification Processes for Complex Biomacromolecules

   Författare :Hans Blom; Helena Grennberg; Mats Lundgren; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chromatography; enzymes; mucins; fractionation; plasmid DNA; analysis; clarification; process design; Chemistry with specialization in Surface Biotechnology; Kemi med inriktning mot ytbioteknik;

   Sammanfattning : This thesis details various techniques and considerations for the purification of complex biomacromolecules. Initially an α-mannosidase from babaco fruit was purified using anion exchange-, lectin affinity- and size exclusion chromatography. LÄS MER

3. 2. Exploring cellulose as a biomacromolecule for enhanced battery metal ion recovery/recycling

   Författare :Billy W. Hoogendoorn; Richard Olsson; Yuanyuan Li; Mikael S. Hedenqvist; Aji Mathew; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biomacromolecules; Nanocellulose; metal oxide nanoparticle synthesis; electrodeposition; battery recycling; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : The research focused on the effects of integrating nanocellulose in the solidification of metal ions into metal oxide particles or metallic electrodeposits.  Firstly, the cellulose was isolated as highly crystalline ca. 15-25 nm thick and 500 nm long fibers from bacterial cellulose using acid hydrolysis and had a negative surface charge.

4. 3. Cryogels as Solid Supports in Bioprocessing

   Författare :Gry Jespersen; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Downstream processing; cryogel; solid support; biomacromolecules; chromatography;

   Sammanfattning : In recent years the market for biopharmaceutical products has been increasing rapidly as a result of an increased demand for new and efficient treatments of various indications. Biopharmaceuticals are distinguished from chemical drugs by being derived from a biological origin and are hence, frequently constituting biological macromolecules. LÄS MER

5. 4. Multilayer Structures for Biomaterial Applications : Biomacromolecule-based Coatings

   Författare :Tobias Halthur; Per M. Claesson; Bjørn Stokke; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multilayer; layer-by-layer deposition; physical chemistry; surface chemistry; adsorption; ellipsometry; QCM-D; DPI; protein adsorption; polypeptides; biomaterials; biosurfaces; amelogenin; solid liquid interface; Surface and colloid chemistry; Yt- och kolloidkemi;

   Sammanfattning : The cellular response to a biomaterial, such as a dental implant, is mainly governed by the surface properties, and can thus be altered by the introduction of a surface coating. In this thesis the buildup of a biomacromolecule-based coating formed by layerby-layer (LbL) deposition of the charged polypeptides poly(L-lysine) (PLL) and poly(L-glutamic acid) (PGA) has been studied.

7. 5. Synthesis and modification of monodisperse polymer particles for chromatography

   Författare :Fredrik Limé; Knut Irgum; Harald D. H: Stöver; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer particles; photoinitiation; precipitation polymerization; styrene; divinylbenzene; atom transfer radical polymerization; liquid chromatography; Analytical chemistry; Analytisk kemi;

   Sammanfattning : Liquid chromatography is an analytical technique that is constantly facing new challenges in the separation of small molecules and large biomacromolecules. Recently the development of ultra high pressure liquid chromatography has increased the demand on sturdy particles as stationary phase. LÄS MER
