1. Development of Nanocellulose Materials for Nano-filtration and Microfluidic Cell Culture
Sammanfattning : Nanocellulose, cellulose nanofibrils or nanocrystals, is an interesting material for a wide range of applications. It can be obtained from abundant sources (higher plants, bacteria and algae), and presents many advantages to be used in the biomedical field such as biological safety, high surface area, porosity, and tailorable rheological properties.

2. Nano and Micro Patterned Organic Devices : From Neural Interfaces to Optoelectronic Devices
Sammanfattning : This thesis describes fabrication methods for optoelectronic devices (light emitting diodes (LEDs) and photodiodes) and structures for neural interfacing (neural electrodes and nerve guidance structures) using semiconducting and conducting organic materials as the active elements. Special importance has been attached to the patterning and processing of these devices. LÄS MER
3. Covalent Surface Modification of Degradable Polymers for Increased Biocompatibility
Sammanfattning : Degradable polymers have gained an increased attention in the field of biomedical applications over the past decades, for example in tissue engineering. One way of improving the biocompatibility of these polymers is by chemical surface modification, however the risk of degradation during the modification procedure is a limiting factor. LÄS MER
4. Advances in Soft Matter Nanofabrication
Sammanfattning : The focus of this thesis is placed on the fabrication of engineered nanodevices for the manipulation of soft matter thin films. By combining top-down micro- and nanofabrication approaches with bottom-up self-assembly strategies, new research platforms were developed, tested and characterized. LÄS MER
5. Functionalized Biomaterial Surfaces by Micro- and Nanofabrication
Sammanfattning : In the field of biomaterials, well-defined nano- and micropatterns or features at material surfaces can serve both as models for investigating material-biosystem interactions and as functional features for inducing, hindering or measuring specific bioreactions or biologic responses. Important bioreactions include protein adsorption and conformation, cell attachment and function, and adhesion and function of organized tissues or whole organisms. LÄS MER
