  1. 1. Pulsed Field Gradient NMR Studies of Diffusion in Polymer Gels

    University dissertation from Chalmers University of Technology

    Author : Diana Bernin; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Bioengineering; Kemiteknik; Chemical engineering; biomaterial; mass transport; diffusion; gel; 1H NMR; 19F NMR; pulsed field gradient NMR; alginate; cellulose; dendrimer;

    Abstract : Soft biomaterials, such as gels, play an important role in different kinds of products and applications, in particular in drug delivery systems, health care products, and food. Polymer gel's great ability to control mass transport is applied on e.g. the uptake of liquids in diapers. READ MORE

  2. 2. Evaluation of Capillary Flow in Gels - The Liquid Uptake of Capillaries and Gelation Mechanisms in Alginate Gels

    University dissertation from Chalmers University of Technology

    Author : Johanna Andersson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Capillary flow; capillary action; alginate gel;

    Abstract : For centuries it has been known that wetting liquids penetrate porous materials if the pores are sufficiently small. In some cases the liquid penetration is desired, like in kitchen paper or diapers, in other systems the penetration should be minimised or avoided, like in water repellent textiles or paper printing.

  3. 3. Controlled release gel formulations and preclinical screening of drug candidates

    University dissertation from Umeå : Department of Chemistry

    Author : Tofeeq Ur-Rehman; Umeå universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; poloxamer; drug delivery; micellization; DMSO; calorimetry; NMR. in situ gelation; chitosan; preclinical pharmacokinetics; type III secretion inhibitors; NATURAL SCIENCES Chemistry Physical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi; Pharmaceutics; galenisk farmaci;

    Abstract : Simple gel formulations may be applied to enhance the systemic and local exposure of potential compounds. The aim of this thesis is the development and characterization of controlled release formulations based on thermo-reversible poloxamer gels, which are suitable for novel drug delivery applications.

  4. 4. Experimental therapeutic angiogenesis after myocardial infarction : Efficacy of different angiogenic factors and delivery methods

    University dissertation from Stockholm : Karolinska Institutet, Department of Medicine at Huddinge University Hospital

    Author : Xiaojin Hao; Karolinska Institutet.; Karolinska Institutet.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiogenesis; arteriogenesis; apoptosis; myocardial infarction; VEGF-A165; bFGF; PDGF-BB; adenovirus; plasmid; alginate;

    Abstract : Angiogenesis, the stimulation of vessel growth, is a promising therapy in ischemic heart disease. A wealth of evidence has shown that several growth factors can induce neovascularization in ischemic models. However, the optimal application of growth factors and delivery method requires further exploration. READ MORE

  5. 5. Nuclear Magnetic Resonance Methods to Study Soft Matter Dynamics and Microstructure

    University dissertation from Chalmers University of Technology

    Author : Diana Bernin; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Soft matter is of great importance for food, hygiene and pharmaceutical products. Gels are an example of soft matter and are found in e.g. diapers, that are able to take up large amounts of liquids. READ MORE
