2. 1. Molecularly Imprinted Polymer Beads-Synthesis, Evaluation and Applications

   Author : Tongchang Zhou; Tillämpad biokemi; []
   Keywords : Molecularly imprinted polymer beads; Pickering emulsion; RAFT; water-compatible;

   Abstract : 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. READ MORE

   Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; regenerated cellulose; partially modified cellulose; capsules; beads; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : 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. READ MORE

5. 3. Application of Raman and Fluorescence Spectroscopy to Single Chromatographic Beads

   Author : Mina Larsson; Jan Lindgren; Jean-Claude Lassègues; Uppsala universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; Chemistry; agarose; chelating group; confocal Raman spectroscopy; confocal scanning laser microscopy; gold nanoparticles; ligand distribution; functional group; neodymium; polymer beads; Raman; SERS; surface-enhanced Raman spectroscopy; Kemi; Chemistry; Kemi;

   Abstract : 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. READ MORE

6. 4. Microfluidic Devices for Manipulation and Detection of Beads and Biomolecules

   Author : Mats Jönsson; Ulf Lindberg; Bertil Hök; Johan Nilsson; Uppsala universitet; []

   Abstract : 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. READ MORE

   Abstract : 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. READ MORE
