  2. 6. Magnetic Nanoparticle Based Biosensors for Pathogen Detection and Cancer Diagnostics

    Author : Bo Tian; Mattias Strömberg; Peter Svedlindh; Hakho Lee; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic biosensors; magnetic nanoparticles; homogeneous assays; volumetric sensing; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Abstract : This thesis describes several magnetic nanoparticle (MNP)-based biosensing strategies which take advantage of different magnetic sensors, molecular tools and nanotechnologies. Proposed biosensors can be classified into three groups, i.e., immunoassay-based, molecular amplification-based, and nanoparticle assembly-based. READ MORE

  4. 7. Ion Tracks for Micro- and Nanofabrication : From Single Channels to Superhydrophobic Surfaces

    Author : Reimar Spohr; Lars Westerberg; Lars Montelius; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ion track; single ion; real time; phase detection; conductometric cell; conductometry; electro replication; microtechnology; nanotechnology; surfactant; self organization; GMR; magnetic; sensor technology; hydrophobic; tilted texture.; Physics; Fysik; Materialvetenskap; Materials Science;

    Abstract : A method is described for preset-count irradiations between 1 and 100 ions singling-out individual ions from an ion beam with more than a billion ions arriving per second. The ion tracks are etched in a conductometric system with real-time evaluation of the acquired data. The etch process can be interrupted when reaching a preset channel diameter. READ MORE

  5. 8. Electromagnetic Modeling and Sensitivity-Based Optimization of Medical Devices

    Author : Oskar Talcoth; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; helical conductors; optimal measurements; thin-wire approximation; inverse problems; Convex optimization; pacemakers; design of experiments; MR safety; multi-scale; magnetic resonance imaging; magnetic tracking; optimal sensor placement;

    Abstract : Electromagnetics is a fundamental part of biomedical engineering and modern healthcare due to the electromagnetic nature of several important processes in the human body and the interactions of electromagnetic fields with the human body. As a consequence, electromagnetics is exploited for diagnostic and therapeutic purposes by a multitude of medical devices. READ MORE

  6. 9. Estimation for Sensor Fusion and Sparse Signal Processing

    Author : Dave Zachariah; Magnus Jansson; Fredrik Gustafsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Estimation theory; sensor fusion; sparse signal processing;

    Abstract : Progressive developments in computing and sensor technologies during the past decades have enabled the formulation of increasingly advanced problems in statistical inference and signal processing. The thesis is concerned with statistical estimation methods, and is divided into three parts with focus on two different areas: sensor fusion and sparse signal processing. READ MORE

  7. 10. Spintronic and Electronic Oscillators for Magnetic Field Sensing and Ising Machines

    Author : Dagur Ingi Albertsson; Ana Rusu; Johan Åkerman; Saul Rodriguez Duenas; Atila Alvandpour; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spintronic Oscillator; Behavioural Modeling; Macrospin Approximation; Magnetic Field Sensor; Ising Machine; Duffing Oscillator; Kuramoto Model; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Oscillators can exhibit a range of complex dynamics which are often encountered in nature. These characteristics include synchronization, injection locking, chaos, bifurcations, etc. To date, the applications of electronic oscillators has mostly been limited to communication systems.
