Development of virus filter using electret apatite complex adsorbent

通过恒定电压施加纯羟基磷灰石(HAP)制备出对病毒具有电吸引作用的纳米晶，称为驻极体HAP(E-HAP)。成纤维细胞和杆状病毒对纯HAP和E-HAP的吸附性能没有差异，但对杆状病毒的吸附量是聚苯乙烯的3倍。为进一步固定化病毒灭活剂，应需要对吸附的病毒进行灭活。

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.
