    Sammanfattning : I denna avhandling beskrivs tillverkning, karaktärisering och tillämpning av ett antal biomimetiska ytor. Biomimetik är att härma naturen och grundtanken är att titta på hur naturen löst liknande problemställningar. LÄS MER

  2. 2. Biomimetic Membranes: Molecular Structure and Stability Studies by Vibrational Sum Frequency Spectroscopy

    Detta är en avhandling från Stockholm : KTH

    Författare :Jonathan F.D. Liljeblad; KTH.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Vibrational Sum Frequency Spectroscopy VSFS ; Langmuir monolayer; LB depositon; phospholipids; oxidation; biomimetic membranes; NATURAL SCIENCES Chemistry Physical chemistry Surface and colloid chemistry; NATURVETENSKAP Kemi Fysikalisk kemi Yt- och kolloidkemi;

    Sammanfattning : In the research presented in this licentiate thesis the surface specific technique Vibrational Sum Frequency Spectroscopy, VSFS, combined with the Langmuir trough has been utilized to investigate Langmuir monolayers and Langmuir-Blodgett (LB) deposited mono- and bilayers of phospholipids. Their molecular structure, stability, and hydration were probed to gain additional understanding of important properties aiming at facilitating the use of such layers as model systems for biological membranes.
