  1. 16. Assessment of the Fluorescent Activities of Different Fluorescent Proteins for Potential Use as Biosensors in Saccharomyces cerevisiae

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Johan Davidsson; [2020]
    Nyckelord :Fluorescent proteins; Saccharomyces cerevisiae; Flow cytometry; CRISPR Cas9; Biosensors; Applied microbiology; Tillämpad mikrobiologi; Technology and Engineering;

    Sammanfattning : Development of genetically modified microorganisms such as Saccharomyces cerevisiae for use as microbial cell factories to produce fine and bulk chemicals has lately proceeded very rapidly, much thanks to new gene editing methods based on a CRISPR/Cas9 system adapted from bacteria which increases the rate of genetic engineering. However, development of methods which enable fast and simple screening of the best performing strains with specific sought-after characteristics is not advancing at the same pace. LÄS MER

  3. 17. Visualization and Classification of Neurological Status with Tensor Decomposition and Machine Learning

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Thi Pham; [2019]
    Nyckelord :Stress assessment; physiological signals; biosensors; tensor decomposition; feature visualization; machine learning;

    Sammanfattning : Recognition of physical and mental responses to stress is important for stress assessment and management as its negative effects in health can be prevented or reduced. Wearable technology, mainly using electroencephalogram (EEG), provides information such as tracking fitness activity, disease detection, and monitoring neurologicalstates of individuals. LÄS MER

  4. 18. Investigating Optical-Field-Induced Currents in GaN using Ultrafast Lasers

    Magister-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Vidar Flodgren; [2019]
    Nyckelord :GaN; gallium nitride; nanoscience; material science; ultrafast lasers; Yb Laser; Pharos Laser; titanium sapphire laser; device fabrication; lift-off; gold etching; optical-field-induced currents; modelling; matlab; Physics and Astronomy;

    Sammanfattning : This study saw the development of an experimental setup capable of generating and measuring optical-field-induced currents in a variety of nanodevices fabricated specifically for this project. Each device design features two metallic contacts, closely separated by about 5 micrometers, deposited onto a semiconductor or insulator substrate. LÄS MER

  5. 19. Field-effect transistor based biosensing of glucose using carbon nanotubes and monolayer MoS2

    Master-uppsats, Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Författare :Nathan Ullberg; [2019]
    Nyckelord :field-effect transistor; biosensor; glucose; carbon nanotube; MoS2; 1D materials; 2D materials; nanotechnology; FET;

    Sammanfattning : As part of the EU SmartVista project to develop a multi-modal wearable sensor for health diagnostics, field-effect transistor (FET) based biosensors were explored, with glucose as the analyte, and carbon nanotubes (CNTs) or monolayer MoS2 as the semiconducting sensing layer.  Numerous arrays of CNT-FETs and MoS2-FETs were fabricated by photolithographic methods and packaged as integrated circuits.

  7. 20. Implementation of thiamine pyrophosphate (TPP) riboswitches as synthetic biosensors and regulatory tools in cyanobacteria

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Hanna Eriksson; [2018]
    Nyckelord :;

    Sammanfattning : The natural occurrence of the non-mevalonate (also called MEP after the compound methyl-erythriol phosphate) pathway in the model cyanobacterium Synechocystis sp. PCC 6803 allows for biosynthesis of various high-value terpenoid compounds. LÄS MER
