In a process for the inactivation of enveloped viruses in a biological fluid buckminsterfullerene (C60) is used as a photosensitizer. In a photodynamicprocesses singlet oxygen is generated which is the active agent for the inactivation of viruses present in the fluid. The process comprises the steps of(a) contacting of a solution or dispersion of material derived from the human body or from the bodies of animals with buckminsterfullerene as a photosensitizer, of (b) saturating the solution or dispersion with oxygen; and of (c) irradiating the solution or dispersion with visible or invisible light for activating the oxygen into the singlet state until viruses contained in the solution or dispersion are inactivated. This virus inactivation is specially suitable forprotein solutions, e.g. bovine serum albumin, BSA or plasma products of human origin.

Dans une méthode pour l'inactivation d'un virus avec enveloppe, dans un fluide biologique, on utilise du buckminsterfullerène (C60) comme photosensibilisateur. Dans une méthode photodynamique, de l'oxygène à singulet est produit, lequel est l'agent actif pour l'inactivation des virus présents dans le fluide. La méthode comprend les étapes suivantes : a) mise en contact d'une solution ou d'une dispersion de matière issue de l'organisme humain ou de corps d'animaux avec le buckminsterfullerène comme photosensibilisateur; b) saturation de la solution ou de la dispersion avec de l'oxygène; c) irradiation de la solution ou de la dispersion par des rayonnements visibles ou invisibles pour l'activation de l'oxygène en singulet jusqu'à inactivation des virus contenus dans la solution ou la dispersion. Cette inactivation virale convient particulièrement bien aux solutions de protéines, p. ex. l'albumine bovine ou les produits plasmatiques d'origine humaine.
