  2. 2. Silicon neural interfaces -Design and biomedical aspects-

    University dissertation from Lars Wallman, Dept. of electrical measurements, box 118, 221 00 LUND

    Author : Lars Wallman; Lund University.; Lunds universitet.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektronik och elektroteknik; Electronics and Electrical technology; pn-etch stop; biocompatibility; neural recordings; porous silicon; silicon; neural interface; sieve electrode; General biomedical sciences; Biomedicinska vetenskaper allmänt ;

    Abstract : This thesis covers the development of a silicon neural interface, with focus on silicon sieve electrode fabrication, design, nerve regeneration, signal recording and biocompatibility. A study of how the via hole size and transparency of the perforated sieve membrane influences the nerve regeneration is presented together with a study on soft tissue responses to planar and porous silicon.

  3. 3. High-resolution biomedical phase-contrast tomography

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : William Twengström; KTH.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; x-ray; x-ray imaging; biomedical; phase contrast; tomography; zebrafish; coronary artery; virtual histology; ring artifacts; phase retrieval; mummy; Physics; Fysik;

    Abstract : Improved three-dimensional biomedical imaging can give a better understanding of tissue structure, growth and diseases. Most present imaging techniques that provide cellular spatial resolution are based on visible or infrared light. These methods cannot image deeper than a millimeter into tissue. READ MORE

  4. 4. Advancing Upconversion Emissions for Biomedical Imaging

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Haichun Liu; Lund University.; Lunds universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; upconverting nanoparticles; luminescence; fluorescence; inverse problem; biomedical optics; biomedical imaging; photon migration; upconversion; tomography; saturation; Fysicumarkivet A:2014:Liu;

    Abstract : During the past decade, upconverting nanoparticles (UCNPs) doped with rare earth ions have become an important class of fluorescence contrast agents for molecular imaging, due to their unique properties. Their property of anti-Stokes luminescence, with both the excitation and emission wavelengths close to the optimal for biomedical imaging, has been extensively explored in various biomedical applications.

  5. 5. Acoustic Trapping in Biomedical Research

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Björn Hammarström; Lund University.; Lunds universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microfluidics; Ultrasound; Acoustic Trapping; Lab-on-a-Chip; Mass Spectrometry;

    Abstract : Herein a method that uses acoustically resonating glass capillaries and enables non-contact capture of micron-sized bioparticles, i.e. acoustic trapping, is described. A miniaturized ultrasonic transducer is used to locally actuate a cross-sectional resonance in the capillary. READ MORE
