2. Synthesis and Characterization of Sec-Packings Based on Trimethylolpropane Trimethacrylate
Sammanfattning : Suspension and bulk polymerization of trimethylolpropane trimethacrylate (TRIM) and copolymerization of TRIM with methyl methacrylate (MMA) resulted in porous, hydrophobic, and chemically crosslinked networks. Copolymerization of TRIM with acrylamide (AA) and with N,N'-methylene-bis-acrylamide (bis-AA) resulted in hydrophilic gels. LÄS MER
3. Models for the Transfer of Drugs from the Nasal Cavity to the Central Nervous System
Sammanfattning : The blood-brain barrier restricts the access of many compounds, including therapeutic agents, to the brain. Several human studies indicate that nasal administration of hydrophilic compounds, such as peptides, can bypass the blood-brain barrier. The aims of this thesis were to develop and refine models for this direct nose-to-brain transfer. LÄS MER
4. Swelling of Cellulose Fibrillar Matrices and Gels
Sammanfattning : One of the major challenges of today´s society is to find a sustainable way to create a living based on the resources on earth. It is a challenge that includes a transition from fossil-based materials to renewable/biodegradable raw materials and also the creation of an environmentally friendly circular material flow. LÄS MER
5. Hyaluronan Derivatives and Injectable Gels for Tissue Engineering
Sammanfattning : The present work describes the preparation of hyaluronan derivatives and hydrogels with potential use in tissue engineering applications. A potentially injectable hydrogel consisting of hyaluronan and collagen was successfully used to grow neurons in vitro by encapsulation of neural stem and progenitor cells. LÄS MER
