  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. Short wavelength UV–LED photoinitiated radical polymerization of acrylate–based coating systems—A comparison with conventional UV curing.

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Olof Torfgård; [2021]
    Nyckelord :UV; LED; UVC; UVB; UVA; paint; acrylate; curing; Sherwin–Williams; ATR-FTIR; spectroradiometer; photoinitiator; the mercury arc lamp;

    Sammanfattning : The present work was performed at Sherwin–Williams Sweden group AB with the objective of comparing short-wavelength light emitting diodes (UVB/UVC) with the conventional mercury arc lamp as a curing method of acrylate-based, UV-paint undergoing free-radical polymerization when exposed to UV-radiation. Due to environmental and health risks, mercury-doped radiation sources will be phased out in the near future, according to the United Nations Minamata convention, hence new alternatives are needed.

  4. 3. Bioconjugation of RGD peptides on injectable PEGDMA for enhancing biocompatibility

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Polymerkemi

    Författare :Victor Thorendal; [2019]
    Nyckelord :Biocompatibility; Bioconjugation; RGD; Polyethylene glycol dimethacrylate PEGDMA ; Photopolymerization; Surface cell adhesion; Injectable; Dynamic cell culture system;

    Sammanfattning : A cerebral aneurysm is a weakened area of an artery in the brain, creating an abnormal expansion. Recent research for treatment is utilizing a photopolymerizable hydrogel as a possible operation for injection in situ. LÄS MER
