  1. 1. UV laser patterning of silicone-based soft electrode grids

    Master-uppsats, Linköpings universitet/Institutionen för teknik och naturvetenskap; Linköpings universitet/Tekniska fakulteten

    Författare :Maria Jakobsson; [2023]
    Nyckelord :Soft electrodes; Wearable electrodes; UV laser; Laser ablation; Laser curing; Polydimethylsiloxane; PDMS; Silver flakes; Teknisk biologi; Teknisk biologi;

    Sammanfattning : Roughly 123 million people worldwide are affected by conditions such as epilepsy, dementia, and cardiovascular diseases. Wearable electrodes are currently used to monitor these conditions short-term. Long-term monitoring would allow for predicting seizures and could be used as a preventive treatment. LÄS MER

  3. 2. Robust and Biocompatible Bonding of Hybrid Microfluidic Devices Using Off-Stoichiometric Thiol-ene Thermosets

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Peter Harris; [2023]
    Nyckelord :OSTE; OSTE ; Microfluidics; Thermoset; Bonding; Thermoplastics; Biocompatibility; OSTE; OSTE ; Mikrofluidik; Härdplast; Binding; Termoplaster; Biokompatibilitet;

    Sammanfattning : Some of the major obstacles the microfluidics industry has yet to overcome in order to facilitate large scale manufacturing of devices are costly back-end processes. Among these, bonding presents some of the most obvious difficulties and is often associated with structural deformation and surface modification. LÄS MER

  4. 3. Design and engineering of light-driven dynamic films for bioelectronic interfacing

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Luca Terenzi; [2023]
    Nyckelord :Conductive polymers; Stimuli responsive materials; Azopolymers; Cell-chip coupling; Bioelectronics; Konduktiva polymerer; Stimuli-känsliga material; Azopolymerer; Cell-chip-koppling; Bioelektronik;

    Sammanfattning : In the realm of neuroelectronics, the challenge lies in achieving finer observations of physiological processes to comprehend neuronal interactions and computations. This necessitates the development of more compliant and biomimetic interfaces for improved integration with biological tissues, enabling finer physiological process observations. LÄS MER

  5. 4. Trade-offs in CRISPR Immunity against Mobile Genetic Elements

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Molekylär systembiologi

    Författare :Johanna Cederblad; [2022]
    Nyckelord :CRISPR; microfluidics; fluorescent microscopy; RP4 conjugative plasmid;

    Sammanfattning : The prokaryotic adaptive immune system CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a defense mechanism that helps to protect the prokaryotic cell from invading mobile genetic elements. This project was performed at Uppsala University and served to answer whether the expression of Cascade, which is part of the CRISPR defense system, will have a negative effect on the cell that expresses it and to also determine whether the CRISPR defense system is effective enough to stop the spread of a conjugative plasmid.

  7. 5. Developing a method for insertion of soft neural probes into peripheral nerves

    Master-uppsats, Linköpings universitet/Laboratoriet för organisk elektronik; Linköpings universitet/Tekniska fakulteten

    Författare :Klara Melander; [2022]
    Nyckelord :Intraneural stimulation; insertion method; peripheral nerve; nerve phantom; peripheral nerve stimulation; Teknisk biologi; Teknisk biologi;

    Sammanfattning : The main objective of this project was to develop a method for soft neural probe insertion into a nerve. These soft probes are made of a silicon elastomer that is a few orders of magnitude less stiff than the nerve, which makes the insertion process particularly challenging. LÄS MER
