SummaryThe activity of nano carbon fullerene lipidosome (NCFL) against influenza virus H1N1 in vitro was studied by observing the cytotoxicities and its activity rendered by different intensities of lighting with various periods of time. Rimantadine hydrochloride was used as the positive control drug. By using microcultural technique, the morphological changes of cells were observed and by using the gentian violet staining, antiviral activity of the NCFL against influenza virus was assayed. The results showed that: (1) The maximal concentration of the NCFL was 7 μg/mL and the 50% toxic concentration (TC50) was 13.54 μg/mL respectively; (2) NCFL had a significant activity of directly killing the influenza virus, while the activities in antiadsorption and antireplication were not obvious; (3) There was a dose-activity relationship between the dosages of NCFL and the direct killing effect against the influenza virus, and the periods of lighting-time could influence the activity partly. It was concluded that NCFL had a significant activity of directly killing the influenza virus.
