Abstract

Our work was focused on obtaining biocomposites from liposomes and carbon nanotubes in order to find the best way for preparing functionalized nanostructures to be used as vectors for therapeutic molecules. Unilamellar liposomes were prepared by thin film hydration method. Chlorophyll a embedded into some of the lipid bilayers was used as a spectral marker to monitor the changes occurred in the liposomal membrane. Single walled carbon nanotubes have been added to liposomes and the biocomposites were studied by spectral methods (UV-VIS absorption and emission, DLS). The nanobiocomposites stability was checked by ξ-potential measurements and by luminol chemiluminescence experiments..
