1. Molecularly Imprinted Polymer Beads-Synthesis, Evaluation and Applications
Sammanfattning : Molecularly imprinted polymers (MIPs) are artificial receptors designed for the selective recognition of template molecules. These polymers have been applied in analytical separations, as chemical sensors and in drug delivery system due to their low cost and high stability. LÄS MER
2. Use of Cellulose for the Preparation of Capsules and Beads with Molecularly Tailored Properties
Sammanfattning : The continuously increasing global production of petroleum-based polymers to meet the ever growing demand for plastics for use in a multitude of industrial sectors (e.g. packaging and textiles) has an impact on human health, climate change and the entire ecosystem. LÄS MER
3. Application of Raman and Fluorescence Spectroscopy to Single Chromatographic Beads
Sammanfattning : Chromatography is a powerful technique, essential in chemical analyses and preparative separation in industry and research. Many different kinds of chromatographic material are needed, due to the large variety of applications. Detailed methods of characterisation are needed to design new chromatographic materials and understand their properties. LÄS MER
4. Microfluidic Devices for Manipulation and Detection of Beads and Biomolecules
Sammanfattning : This thesis summarises work towards a Lab-on-Chip (LOC). The request for faster and more efficient chemical and biological analysis is the motivation behind the development of the LOC-concept. Microfluidic devices tend to become increasingly complex in order to include, e.g. LÄS MER
5. Study of Paper Dry Strength Additives on Cellulose Fibres
Sammanfattning : Paper packaging is commonly found in the form of paper and cardboard boxes, but recently paper packing is being used in food packaging, trays, beverage packaging and even paper straws, among others. Paper strength additives have been developed to increase the efficiency of the joint strength and the joint areas and potentially maintain bulk in paper products. LÄS MER
