2. 1. Physico-Chemical Investigations of Bilayer Discs and Related Lipid Structures Formed in Liposomal Systems Intended for Triggered Release

   Author : Maria Sandström; Katarina Edwards; Mats Almgren; Tommy Nylander; Uppsala universitet; []
   Keywords : Physical chemistry; liposome; triggered release; pH-sensitive liposomes; temperature-sensitive liposomes; drug partitioning; cryo-TEM; discs; Fysikalisk kemi;

   Abstract : This thesis describes results from fundamental studies of liposomes intended for drug delivery and pH or temperature triggered release. In addition, the effect of lipid composition on bilayer disc formation and a potential application of the bilayer discs were investigated. READ MORE

4. 2. Hybrid Plasmonics for Energy Harvesting and Sensing of Radiation and Heat

   Author : Mina Shiran Chaharsoughi; Magnus Jonsson; Xavier Crispin; Simone Fabiano; Eunkyoung Kim; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The special optical properties of subwavelength metallic structures have opened up for numerous applications in different fields. The interaction of light with metal nanostructures leads to the excitation of collective oscillations of conduction-band electrons, known as plasmons. READ MORE

5. 3. Studies on Translation Initiation and Termination in Escherichia coli

   Author : Georgina Ibrahim Isak; Leif Isaksson; Suparna Sanyal; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; translation; ribosome; IF1; RF1; kasugamycin; tRNA; molekylärgenetik; Molecular Genetics;

   Abstract : Translation initiation factor 1 (IF1) has been shown to be an RNA chaperone. In order to find functional interactions that IF1 may have with rRNA, we have isolated second-site suppressors of a cold-sensitive IF1 mutant. READ MORE

   Author : Yujia Jing; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cationic lipid; asymmetry; phospholipase; liposomes; flip-flop; hyperthermia; phase transition; supported lipid membranes; drug delivery;

   Abstract : Abstract Sophisticated liposomal systems are emerging at an increasing rate to meet the demands for multifunctional drug carriers in chemotherapies in combined with hyperthermia. For example, liposomal drug carriers for temperature-controlled drug release under hyperthermic conditions have recently been tested in clinical trials. READ MORE

7. 5. Synthesis of nanostructured and hierarchical materials for bio-applications

   Author : Fei Ye; Mamoun Muhammed; Andreas Fisher; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fe3O4; mSiO2; core-shell; MRI; multifunctional; PNIPAAm; LCST; gold; nanorod; nitric acid; AR; MDDC; biocompatibility; immunomodulation; Materials chemistry; Materialkemi;

   Abstract : In recent years, nanostructured materials incorporated with inorganic particles and polymers have attracted attention for simultaneous multifunctional biomedical applications. This thesis summarized three works, which are preparation of mesoporous silica coated superparamagnetic iron oxide (Fe3O4@mSiO2) nanoparticles (NPs) as magnetic resonance imaging T2 contrast agents, polymer grafted Fe3O4@mSiO2 NPs response to temperature change, synthesis and biocompatibility evaluation of high aspect ratio (AR) gold nanorods.
