1. 1. Development and Multicolor Imaging Applications of Lanthanide-Based Luminescent Probes

   Författare :Elias Pershagen; K. Eszter Borbas; Stéphane Petoud; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lanthanide; luminescent probe; multicolor; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

   Sammanfattning : The study of biological analytes in their native environment is a major challenge for biochemistry and molecular biology.  Luminesce spectroscopy is well suited for this task due to its non-invasiveness, high spatial and temporal resolution, and high signal to noise ratio.

3. 2. Poly-and oligothiophenes : Optical probes for multimodal fluorescent assessment of biological processes

   Författare :Karin Magnusson; Peter Nilsson; Per Hammarström; Thomas Borén; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : One interesting class of molecules in the research field of imaging biological processes is luminescent conjugated polythiophenes, LCPs. These fluorescent probes have a flexible backbone consisting of repetitive thiophene units. LÄS MER

4. 3. Anionic oligothiophenes : Optical tools for multimodal fluorescent assignment of protein aggregates

   Författare :Rozalyn Simon; Peter Nilsson; Sara Snogerup Linse; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Luminescent conjugated oligothiophenes (LCOs) represent a useful and interesting class of materials well known for their abilities as transducers for colorimetric and fluorometric reporting. Specifically, they have the ability to produce a conformation-dependent spectral signature reflective of changes in their local environment. LÄS MER

5. 4. Organic Azides : Functional Molecules and Materials

   Författare :Giampiero Proietti; Peter Dinér; Per I. Arvidsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; perfluorinated Aromatic Azide; Photoactivatable; fluorophores; aggregation-induced emission; sulfonimidamides; sulfoximes; chiral auxilary; organogel; azides reduction; Ni-B; Kemi; Chemistry;

   Sammanfattning : The work presented in this thesis stems from the chemistry of the azido group, and more specifically from the unique reactivity of perfluorinated aromatic azides and how to use this reactivity to access new types of molecules to enable new applications in asymmetric synthesis and materials.In the first section of this thesis, a photoactivatable fluorescence probe is presented, where the non-luminescent azide was activated via a UV-light-promoted intramolecular N–H insertion reaction forming a fluorescence emitter.

7. 5. Metal Oxide Nanoparticles for Contrast Enhancement in Magnetic Resonance Imaging : Synthesis, Functionalization and Characterization

   Författare :Maria Ahrén; Kajsa Uvdal; Jan Kehr; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : This thesis work focuses on the design and production of nanoparticle based contrast agents for signal enhancement in magnetic resonance imaging (MRI). Three different synthesis routes are explored, primarily to produce crystalline gadolinium oxide (Gd2O3) nanoparticles, and surface modification is done to obtain stable, dispersible, biocompatible probes inducing high proton relaxivities.
