11. Nano- and Micro-sized Molecularly Imprinted Polymer Particles on Solid Surfaces
Sammanfattning : Molecularly imprinted polymers (MIPs) are artificial receptors made by imprinting template molecules in a polymer matrix followed by their removal through washing to obtain a specific and selective template cavities. This property of the MIPs have made them a very efficient material for diverse applications such as chromatography, purification, drug sensing, etc. LÄS MER
12. Bioelectrochemical Applications of Reactions Catalyzed by Immobilized Enzymes
Sammanfattning : The sensitivity of biosensors can be increased substantially by incorporation in a substrate recycling scheme. Based on the amplification of NAD+/NADH by the recycling reaction catalyzed by glycerol dehydrogenase (GDH) and diaphorase, NAD+/NADH can be determined amperometrically with around 1000 times higher sensitivity than for the substrate sensing mode.

13. Multiscale X-ray Characterisation of Cellulose-based Solid Dispersions
Sammanfattning : Cellulose-based solid dispersions are a promising formulation strategy for providing controlled drug release and dissolution enhancement of poorly soluble drugs. These dispersions can from structures on multiple length scales which can have both positive and negative effects on the functional properties of the formulation. LÄS MER
14. GC-MS based metabolomics – Development of a next generation GC-MS method and its application to nutrition and biomarker research
Sammanfattning : Metabolomics, the measurement of a broad range of small molecules in a sample, is maturing as a field in analytical chemistry and becoming a standard research tool in biological sciences for helping to generate a wider understanding of the complex biological mechanisms behind, for example, development of disease and effects of diet on health. Metabolomics analysis is generally divided into either targeted or untargeted metabolomics. LÄS MER
15. Sample Handling Techniques in Biological and Environmental Applications Emphasizing Biomolecular Recognition and MALDI-TOF MS
Sammanfattning : The use of restricted access media and other stationary phases for clean-up and trace enrichment of environmental samples coupled on-line to liquid chromatography using diode array detection as well as thermospray MS is described. This on-line configuration was compared with commercially available ELISAs for the determination of triazines in complex matrices, showing superior precision and accuracy with the chromatographic method.
