Abstract: A composition including long-term storable plasma-activated liquid (liquid plasma) as an active ingredient is disclosed. The long-term storable, atmospheric-pressure, plasma-activated liquid is prepared by dissolving a plasma generated using a low-temperature microplasma jet in a solution. The plasma-activated liquid not only exhibits a cancer cell killing effect at a level similar to gas-phase plasma according to a conventional art, but also maintains the cancer cell killing effect even when the plasma-activated liquid is stored in a freezer or in a cold chamber for 6 months, and thus is suitable for long-term storage. The plasma-activated liquid may be effectively used in the biopharmaceutical field, for example for a skin regeneration, wound-healing of dermal cells, and/or treating a cancer.

Abstract: The present invention relates to a method for inducing apoptosis of disease cells and disease-causing micro-organisms using plasma for bio-medical use, the method comprising the steps of: generating plasma by means of a high-pressure plasma jet produced using a micro-electro-mechanical system (MEMS) technique; plasma-processing by applying a solution with the plasma; exposing cells to the plasma-processed solution; and inactivating disease cells and disease-causing micro-organisms from among the exposed cells. According to the present invention, after applying plasma to a solution such as a buffer solution or water, targets to be processed such as micro-organisms or animal or plant cells are exposed thereto, and thus the present invention can be used in both bio and medical fields, and has the benefit of effectively inducing apoptosis of disease cells and disease-causing micro-organisms with low power due to indirect processing.
