2. 1. Monolithic separation media synthesized in capillaries and their applications for molecularly imprinted networks

   Author : Julien Courtois; Knut Irgum; Ruth Freitag; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; bupivacaine; etching; phosphorylated tyrosine; poly ethylene glycol ; silanization; transmission electron microscopy; fused silica capillaries; isothermal titration calorimetry; local anæsthetic; molecularly imprinted polymer; monolith; nuclear magnetic resonance; Analytical chemistry; Analytisk kemi;

   Abstract : The thesis describes the synthesis of chromatographic media using several different approaches, their characterizations and applications in liquid chromatography. The steps to achieve a separation column for a specific analyte are presented. The main focus of the study was the design of novel molecularly imprinted polymers. READ MORE

4. 2. Advances in Separation Science : . Molecular Imprinting: Development of Spherical Beads and Optimization of the Formulation by Chemometrics

   Author : Henrik Kempe; Anders Colmsjö; Ulrika Nilsson; Jan Åke Jönsson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chromatography; Parameter estimation; Diffusion; Molecularly imprinted polymer; Suspension polymerization; Chemometrics; Analytical chemistry; Analytisk kemi;

   Abstract : An intrinsic mathematical model for simulation of fixed bed chromatography was demonstrated and compared to more simplified models. The former model was shown to describe variations in the physical, kinetic, and operating parameters better than the latter ones. READ MORE

5. 3. POROUS POLYMERS AND DESIGNED SORBENTS FOR APPLICATIONS IN BIOMEDICAL RESEARCH

   Author : Mariana Duarte; Avdelningen för Biomedicinsk teknik; []
   Keywords : polymers; sorbents; polymer porosity; selective extraction; biomarkers; molecularly imprinted polymers;

   Abstract : Everyday millions of bioanalyses are performed in clinical laboratories, hospitals and research centers, where technicians and bio-analysts utilize analytical chemistry principles and instruments to serve medicine and biomedical research. A method routinely used for sample preparation in bioanalysis is solid-phase extraction (SPE). READ MORE

6. 4. Porous degradable polyester scaffolds

   Author : Peter Plikk; Ann-Christine Albertsson; Johan Lind; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; aliphatic polyester; copolymer; porous scaffold; ring-opening polymerization; electron beam; gamma irradiation; Polymerteknologi; Chemistry; Kemi;

   Abstract : Tissue engineering is a growing research field in which degradable porous scaffolds are used to regenerate tissue from the patients own cells. The problems due to donor shortage or the lack of full property restoration from prosthetic implants can thereby be overcome. READ MORE

7. 5. Porous polymeric materials for chromatography : Synthesis, functionalization and characterization

   Abstract : Background: Separation science is heavily reliant on materials to fulfill ever more complicated demands raised by other areas of science, notably the rapidly expanding molecular biosciences and environmental monitoring. The key to successful separations lies in a combination of physical properties and surface chemistry of stationary phases used in liquid chromatographic separation, and this thesis address both aspects of novel separation materials.
