  5. 24. Development of Cellulose-Based, Nanostructured, Conductive Paper for Biomolecular Extraction and Energy Storage Applications

    Författare :Aamir Razaq; Albert Mihranyan; Srømme Maria; Leif Nyholm; Johan Bobacka; Uppsala universitet; []
    Nyckelord :Polypyrrole; Cladophora cellulose; Conductive paper; Electrochemically controlled ion-exchange; DNA extraction; Paper-based energy storage devices; Chopped Carbon fibers; Teknisk fysik med inriktning mot nanoteknologi och funktionella material; Engineering Science with specialization in Nanotechnology and Functional Materials;

    Sammanfattning : Conductive paper materials consisting of conductive polymers and cellulose are promising for high-tech applications (energy storage and biosciences) due to outstanding aspects of environmental friendliness, mechanical flexibility, electrical conductivity and efficient electroactive behavior. Recently, a conductive composite paper material was developed by covering the individual nanofibers of cellulose from the green algae Cladophora with a polypyrrole (PPy) layer. LÄS MER

  7. 25. Mesoporous magnesium carbonate as a drug delivery vehicle for stabilising amorphous drugs and regulating their release rate

    Författare :Peng Zhang; Maria Strømme; Niklas Hedin; Uppsala universitet; []
    Nyckelord :mesoporous; magnesium carbonate; drug delivery; solubility enhancement; bioavailability; pharmacokinetics; diffusion release; controlled release; Teknisk fysik med inriktning mot nanoteknologi och funktionella material; Engineering Science with specialization in Nanotechnology and Functional Materials;

    Sammanfattning : In today’s drug discovery, the number of candidate drugs based on new molecular entities with poor aqueous solubility is increasing. Since poor aqueous solubility of an active pharmaceutical ingredients (APIs) is associated with low bioavailability and thus limite their therapeutic effect, this is often a great challenge in the development of new drugs when oral administration is the preferred route of administration.
