  1. 1. Assessment of a Light-Activated Adhesive for Hernia Mesh Repair

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Ludivine Amathieu; [2021]
    Nyckelord :Intraperitoneal laparoscopic ventral hernia repair; Light-activated adhesive; Acrylate conversion; Cross-linking quantification; Fixation strength performance;

    Sammanfattning : Background and objectives: TISSIUM light-activated adhesive was investigated as an alternative to tissue-penetrating products to fix meshes in intraperitoneal laparoscopic ventral hernia repair. The objective of this study was to ensure efficient polymer light activation through commercial meshes and to assess the acute and chronic fixation strength of the light-activated adhesive in a porcine model in comparison to commercial fixation products.

  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. Design of Multi-function Polymeric Nanoparticles for Theranostic Application

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Zuhoor Yamani; [2019]
    Nyckelord :theranostic; polymeric nanparticles; drug delivery; camptothecin; nile red; encapsulation during particle formation;

    Sammanfattning : Block copolymer nanoparticles (NPs) have gained great attention among researcher for various medical application mainly due to their extraordinary optical, chemical, and biological properties. The current thesis presents design of multifunctional polymeric NPs for imaging and drug delivery system (DDS) with an in-vitro study of their participation in drug release and cell viability. LÄS MER
