  2. 21. Exploring nanosystems for biomedical applications focusing on photodynamic therapy and drug delivery

    Author : Vladimir Kirejev; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Photodynamic therapy; PDT enhancement; Nitric oxide; NO-based PDT; Targeted drug delivery; Galectin-3; mTHPP; Cyclodextrin; CD-mTHPP conjugate; PpIX AuNP combination; Two-photon microscopy; FLIM; Cell phototoxicity; Ex vivo skin;

    Abstract : The increasing incidences of cancer and related deaths call for the development of new and improved treatment modalities. Photodynamic therapy (PDT) today is an alternative to conventional treatments, but has limitations. This thesis explores different nanosystems with aim to improve PDT focusing on spectroscopic and ex vivo studies. READ MORE

  4. 22. New strategies for multifunctional antibacterial materials

    Author : Hengzhi Ruan; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hydrogel; antibacterial coatings; multifunctional materials;

    Abstract : Healthcare-associated infections (HAI) are responsible for significant financial and human costs in healthcare systems. Therefore, a substantial amount of research has been devoted to developing biopolymer-based strategies that prevent bacterial attachment and biofilm formation on surfaces. READ MORE

  6. 24. Design and engineering of human transferrin receptor 1 and its binding proteins

    Author : Dick J. Sjöström; Sinisa Bjelic; John Löfblom; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Transferrin receptor; Machupo virus; protein engineering; Rosetta; flow cytometry; directed evolution; Biomedical Sciences; Biomedicinsk vetenskap;

    Abstract : The human transferrin receptor 1 (TfR) is central in maintaining adequate cellular iron levels with the iron carrier proteins transferrin (Tf) and ferritin (Ft). Known to bind TfR is also HFE, another iron regulatory protein, competing with Tf for receptor binding. READ MORE

  7. 25. Advancing Upconversion Emissions for Biomedical Imaging

    Author : Haichun Liu; Atomfysik; []
    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.
