The surface modification of materials by plasma cleaning technology at the micro-scale does not affect the material properties:
With the basic research of plasma science, the need for fusion experiments, and the increasing industrial demand for reliable plasma processing systems, plasma cleaning technology and equipment have gradually evolved from gas discharge equipment in the 19th century to modern advanced production equipment. The methods of ionizing gas through direct current, radio frequency and microwave electric fields can all be used to make plasma sources.

Plasma cleaning technology provides an environmentally friendly and economical method for surface modification of materials on a microscopic scale, and does not require mechanical processing and chemical reagents in the modification process. Plasma cleaning technology can not only achieve cleaning, activation, and etching on the surface of the material, but also modify and optimize the surface of plastic, metal or ceramic materials, improve their bonding ability or give new surface properties. Its potential medical value includes improving the hydrophilic or hydrophobic properties of the material surface, reducing surface friction and improving the barrier properties of the material surface. At present, various surface modification technologies are being actively studied at home and abroad to achieve the purpose of controlling tissue adhesion, reducing tissue resistance, anti-embolism or infection, and as an inhibitor of chemotherapy or removing certain specific protein cells. The focus is on short-term research. Or it will affect the surface properties of the tissue reaction in the long term.
Plasma treatment does not affect the physical properties of the material. Compared with the part that has not been treated by plasma technology, the part of the material treated by plasma is generally indistinguishable visually and physically. At present, plasma cleaning technology is usually used to control the wettability of test tubes and laboratory utensils, the treatment of vascular balloons and catheters before adhesion, the treatment of blood filtration membranes, and the surface properties of biological materials to improve or inhibit cell growth. The growth state of the surface of these materials.
