Homogeneous and stable (+)-usnic acid loaded liposomes prepared by compressed CO2

This work was financially supported by the Ministry of Economy, Industry and Competitiveness of Spain through the “MOTHER” project (MAT2016-80826-R). Furthermore, the research leading to these results has received funding from the European Union’s Horizon 2020 research and innovation program under the Marie Sklodowska-Curie grant agreement N° 712949 (TECNIOspring PLUS) and from the Agency for Business Competitiveness of the Government of Catalonia. The preparation of liposomes and their characterization were performed by the ICTS “NANBIOSIS”, more specifically by the Biomaterial Processing and Nanostructuring Unit (U6), Unit of the CIBER in Bioengineering, Biomaterials & Nanomedicine (CIBER-BBN) located at the Institute of Materials Science of Barcelona (ICMAB-CSIC)
