  1. 1. Silicon Nanoribbon FET Sensors : Fabrication, Surface Modification and Microfluidic Integration

    Författare :Roodabeh Afrasiabi; Jan Linnros; Michel Calame; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Over the past decade, the field of medical diagnostics has seen an incredible amount of research towards the integration of one-dimensional nanostructures such as carbon nanotubes, metallic and semiconducting nanowires and nanoribbons for a variety of bio-applications. Among the mentioned one-dimensional structures, silicon nanoribbon (SiNR) field-effect transistors (FET) as electro-chemical nanosensors hold particular promise for label-free, real-time and sensitive detection of biomolecules using affinity-based detection.

  3. 2. Position Sensitive Detectors : Device Technology and Applications in Spectroscopy

    Författare :Henrik Andersson; Hans-Erik Nilsson; Göran Thungström; Jan Linnros; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Position sensitive detectors; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : This thesis deals with the development, processing and characterization of position sensitive detectors and, in addition, to the development of compact and cost effective spectrometers. Position sensitive detectors are used to measure, with great accuracy and speed, the position of a light spot incident on the surface. LÄS MER

  4. 3. Electrochemically etched pore arrays in silicon for X-ray imaging detectors

    Författare :Xavier Badel; Jan Linnros; Volker Lehmann; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrophysics; Elektrofysik; Electrophysics; Elektrofysik;

    Sammanfattning : Digital devices have now been introduced in many X-ray imaging applications, replacing slowly traditional photographic films. These devices are preferred as they offer real time imaging, easy handling and fast treatment of the images. LÄS MER

  5. 4. Fabrication and characterization of single luminescing quantum dots from 1D silicon nanostructures

    Författare :Benjamin Bruhn; Jan Linnros; Luca Dal Negro; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; silicon; quantum dot; nanocrystal; nanowire; nanostructure; photoluminescence;

    Sammanfattning : Silicon as a mono-crystalline bulk semiconductor is today the predominant material in many integrated electronic and photovoltaic applications. This has not been the case in lighting technology, since due to its indirect bandgap nature bulk silicon is an inherently poor light emitter. LÄS MER

  7. 5. Development of Techniques for Characterization, Detection and Protein Profiling of Extracellular Vesicles

    Författare :Sara Cavallaro; Jan Linnros; Apurba Dev; Hakho Lee; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular vesicles; streaming current; fluorescence microscopy; atomic force microscopy; scanning electron microscopy; protein profiling; size profiling; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : Nanosized extracellular vesicles (EVs, ∼30-2000 nm) have emerged as important mediators of intercellular communication, offering opportunities for both diagnostics and therapeutics. In particular, small EVs generated from the endolysosomal pathway (∼30-150 nm), referred to as exosomes, have attracted interest as a suitable biomarker for cancer diagnostics and treatment monitoring based on minimally invasive liquid biopsies.
