This article describes the photodynamic inactivation of mosquito iridescent virus (MIV) Aedes flavescens in the presence of water-soluble C(60) fullerenes. It has been observed that the photodynamic inactivation of MIV for about 1 h reduces the infectious titre of the virus in large wax-moth larvae Galleria mellonella to 4.5 lg ID(50)/mL. The influence of the C(60) concentration on its anti-viral activity was tested in the concentration range from 1 to 0.001 mg/mL. It has been found that C(60) is able to inactivate the iridovirus even in low concentrations. Consequently, the findings of this work suggest that photoexcited C(60) fullerenes can be successfully used for the inactivation of iridoviruses in biological systems.

It was shown that water soluble C 60 fullerenes under visible light interact with iridovirus virions of mosquito Aedes flavescens and lead to their destruction. Specifically, the photodynamic inactivation of mosquito iridovirus during 1 h reduced the infectious virus titer in large wax-moth larvae Galleria mellonella on 4 lg ID50/ml. Therefore, for inactivation of iridoviruses in biological systems it is appropriate to use the photoexcited C 60 fullerenes.
