Development of virus filter using electret apatite complex adsorbent

Hydroxyapatite nanocrystals(HAp) with the property of electrical attraction to virus was developed by applying pure HAp at a constant voltage, called as electret HAp(E-HAp). The adsorption properties of fibroblast and baculovirus to pure HAp and E-HAp have no difference ; however, the amount of adsorbed baculovirus to pure HAp was three times higher than that of polystyrene. Inactivation of the adsorbed virus should be needed for the further immobilization of a virus inactivation agency.
