  1. 6. 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

  3. 7. Oxidized Cladophora nanocellulose derivatives : Functionalization towards biocompatible materials

    Författare :Igor Rocha; Jonas Lindh; Natalia Ferraz; Albert Mihranyan; Maria Strömme; Eva Malmström Jonsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cladophora nanocellulose; TEMPO oxidation; periodate oxidation; sulfonation; cellulose beads; surface properties; biomaterials; cell studies; hemocompatibility;

    Sammanfattning : Nanocellulose is a promising candidate for biomedical applications because of its enhanced mechanical properties, increased surface area and greater porosity compared to bulk cellulose.This thesis investigates the functionalization of Cladophora nanocellulose and evaluates the influence of these modifications on physicochemical properties and biocompatibility of the material.

  4. 8. Hydrogels of Poly(vinyl alcohol) and Nanocellulose for Ophthalmic Applications : Synthesis, Characterization, Biocompatibility and Drug Delivery Studies

    Författare :Gopi Krishna Tummala; Albert Mihranyan; Natalia Ferraz; Cecilia Persson; Jonas Lindh; Che Connon; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanocellulose; poly vinyl alcohol ; hydrogel; cornea regeneration; therapeutic lens; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : Hydrogels are commonly used materials in ophthalmic care as contact lenses, bandage lenses, corneal implants, and cornea regeneration scaffolds. Hydrogels can be produced by physical, chemical, or radiation crosslinking of hydrophilic polymers. LÄS MER

  5. 9. Virus retentive filter paper for processing of plasma-derived proteins

    Författare :Lulu Wu; Albert Mihranyan; Margareta Krabbe; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasma-derived biologics; human serum albumin; human plasma-derived immunoglobulin; virus removal filtration; Cladophora cellulose; quality control; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : The studies in the present thesis explored the feasibility of using nanocellulose-based filters in virus removal filtration of plasma-derived proteins. In Paper I, two-step nanofiltration of commercially available human serum albumin (HSA) product, which was diluted to 10 g L-1 by phosphate buffer saline (PBS) and adjusted pH to 7.
