2. 1. Miniaturized localized surface plasmon resonance biosensors

   Author : Si Chen; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; colloidal lithography; Surface plasmon resonance; biosensing; electron beam lithography; single molecule; hyperspectral imaging; photo functionalization;

   Abstract : Abstract Reliable and sensitive biosensors are required for fast and accurate diagnostics. Localized surface plasmon resonances (LSPRs) in noble-metal nanoparticles possess very high refractive index sensitivity close to the metal surface and therefore constitute an attractive biosensing platform.

4. 2. Nonlinear dynamics of strongly-bound magnetic vortex pairs

   Author : Artem Bondarenko; Vladislav Korenivski; Gleb Kakazei; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; magnetic vortex; nonlinear mechanics; isolated resonance; nonlinear frequency tuning; chaotic dynamics; parametric interaction; Thiele equation; Monte Carlo simulations; Ito processes; bistability; tunneling magneto-resistance; Magnetisk-virvel; icke-linjär dynamik; isolerad resonans; icke-linjär frekvens-optimering; kaotisk dynamik; parametrisk interaktion; Thiele-ekvation; Monte Carlo-simuleringar; Ito-processer; bistabilitet; tunnelmagneto-resistans.; Fysik; Physics;

   Abstract : This work is a study of nonlinear phenomena in vertically stacked pairs of magnetic vortices. New dynamic regimes are uncovered with a decrease in the inter-vortex separation to below the lateral vortex-core size. READ MORE

5. 3. Degradation, Metabolism and Relaxation Properties of Iron Oxide Particles for Magnetic Resonance Imaging

   Author : Karen Briley Saebo; Håkan Ahlström; Atle Bjørnerud; Michael Knopp; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Magnetic Resonance Imaging; contrast agents; iron oxide particles; metabolism; relaxation mechanisms; Radiologisk forskning; Radiological research; Radiologisk forskning;

   Abstract : Whereas the effect of size and coating material on the pharmacokinetics and biodistribution of iron oxide based contrast agents are well documented, the effect of these parameters on liver metabolism has never been investigated. The primary purpose of this work was to evaluate the effect of iron oxide particle size and coating on the rate of liver clearance and particle degradation using a rat model. READ MORE

6. 4. Dynamics of the interstellar matter in galaxies : isolated barred spiral galaxies : cloud formation processes

   Author : Kristen Helmuth; John Beckman; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Astronomi; Astronomy; astronomi;

   Abstract : The dynamical components of six isolated barred spiral (SB) galaxies are investigated. No evidence is found supporting the hypothesis of a low amount of dark matter being characteristic of SB galaxies. The presence of companion galaxies is found to correlate with an increased statistical spread in the neutral hydrogen (HI) extent. READ MORE

7. 5. Traumatic isolated rupture of the knee medial collateral ligament : diagnosis and long term effects

   Author : Magnus Lundberg; Per Renström; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Isolated partial rupture of the knee medial collateral ligament (MCL) is the most common traumatic knee ligament injury. Owing to the good short- and medium-term functional results after conservative treatment, this injury has been regarded as harmless. READ MORE
