1. 16. Event Detection in Eye-Tracking Data for Use in Applications with Dynamic Stimuli

   Författare :Linnéa Larsson; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This doctoral thesis has signal processing of eye-tracking data as its main theme. An eye-tracker is a tool used for estimation of the point where one is looking. Automatic algorithms for classification of different types of eye movements, so called events, form the basis for relating the eye-tracking data to cognitive processes during, e.g. LÄS MER

3. 17. Strategies for Miniaturized Biomarker Detection

   Författare :Belinda Adler; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomarker; miniturization; lab-on-a-chip; proteomics; PSA; microarray; mass spectrometry; MALDI MS; SPE; sample preparation; immunoaffinity; antibody; aptamer; mass tag; ISET.;

   Sammanfattning : The aim of this thesis is development and application of different miniaturized strategies for detection of biomarkers. The biomarker PSA (prostate specific antigen), which is prostate cancer specific, has been the main focus of the thesis. LÄS MER

4. 18. Development of Magnetomotive Ultrasound Imaging

   Författare :Maria Evertsson; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetomotive ultrasound; molecular imaging; contrast angents; multimodal imaging; sentinel lymph node;

   Sammanfattning : The earlier abnormalities coupled with disease can be discovered in the body, the larger is the chance to survive the disease. Molecular imaging is a growing research field which aims to detect these abnormalities at a molecular level, when the chance of survival is still high. LÄS MER

5. 19. On microchannel acoustophoresis - Experimental considerations and life science applications

   Författare :Per Augustsson; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microtechnology; microfluidics; lab on a chip; separation; acoustophoresis; ultrasound; acoustic resonance; acoustic radiation force; phage display; circulating tumour cells; acoustofluidics;

   Sammanfattning : This thesis presents experimental studies of microchannel acoustophoresis, a technique for manipulation of microscopic objects in suspension by means of acoustic radiation forces induced by ultrasonic standing wave fields. By arranging an acoustic resonance across the width of a microchannel, the path of individual cells or microparticles can be deflected orthogonally to the fluid flow. LÄS MER

7. 20. Porous Silicon -an enzyme coupling matrix for micromachined reactors

   Författare :Johan Drott; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Instrumentation technology; glucose; biosensor; immobilised enzyme; porous silicon; microreactor; Mät- och instrumenteringsteknik;

   Sammanfattning : The development of a miniaturised silicon wafer integrated enzyme reactor is described. The reactor was micromachined by anisotropic wet etching of (110) silicon. The enzyme glucose oxidase (GOx) was coupled to the reactor surface with standard methods of immobilising enzyme to silica. LÄS MER
