Abstract

Supported phospholipid bilayers (SPB) with chlorophyll a (Chla) constitute a new approach in using the lipids and Chla as promising biological materials for optoelectronic applications. The objective of the present work was to obtain supported Chla-lipid membranes by using liposomes with Chla incorporated in the bilayer and to characterize the structures by using optical methods. Chla, was used as spectral marker and molecular sensor in VIS absorption and emission studies and the kinetics of the lipid deposition was investigated by using an optical based method - Surface Plasmon Resonance (SPR). The type and dimension of lipid vesicles and the presence of Chla proved to be important factors for the kinetics of phospholipid vesicles deposition..
