Claims9
A process of plasma sterilization using hydrogen peroxide as a precusor of the active species in the plasma comprising the steps of:
- placing an item to be sterilized in a chamber,
- contacting the item with a hydrogen peroxide vapor for a pretreatment time period which is a sufficient time period to allow the hydrogen peroxide to come in close proximity with the item;
- generating a hydrogen peroxide plasma around the item, and
- maintaining the item in said hydrogen peroxide plasma for a time period sufficient to allow an active species generated from the hydrogen peroxide plasma to effect sterilization.
