Abstract:
In the last decade, research in nanotechnology field has known a rapid progress. Because of their unique properties, the nanomaterials based on carbon nanotubes (CNTs) have broad applications in nanomedicine. Our work was focused on building biohybrid systems based on CNTs, conducting polymers and artificial lipid bilayers in order to prepare functionalized carbon-based nanostructures to enhance their biocompatibility in biomedical applications. Different biophysical studies are performed to characterize these systems: oxidative stress studies (luminol chemiluminescence assay), spectral methods (DLS, absorption and emission in UV-VIS).
