  5. 4. 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 :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  7. 5. Biosensor surface chemistry for oriented protein immobilization and biochip patterning

    Författare :Emma Ericsson; Karin Enander; Sofia Svedhem; Linköpings universitet; []
    Nyckelord :Biochip; biosensor; hydrogel; ligand; orientation; patterning; photochemistry; protein immobilization; surface chemistry; self-assembled monolayer; SAM;

    Sammanfattning : This licentiate thesis is focused on two methods for protein immobilization to biosensor surfaces for future applications in protein microarray formats. The common denominator is a surface chemistry based on a gold substrate with a self-assembled monolayer (SAM) of functionalized alkanethiolates. LÄS MER
