Biohybrids Based on Carbon Nanotubes and Liposomes - Biophysical Studies
This paper presents a simple and effective bottom-up approach to design novel biohybrids based on biomimetic membranes and carbon nanotubes. Multilamellar and unilamellar lipid vesicles loaded with two antioxidants (quercetin and chlorophyll a) were obtained by thin film hydration method and have been used to prepare two types of biohybrid systems by addition of carbon nanotubes to these liposome suspensions. Chlorophyll a inserted into biomimetic membranes was used as a spectral marker to detect the changes occurred in the artificial lipid bilayers. The obtained carbon-based biohybrids exhibited antioxidant and antimicrobial properties and also a good physical stability.
