surface modification method
Introduce some specific element or functional group onto thesurface of materials.
Specific functional groups provide special chemical reactivity and varying physical properties for surface
A variety of molecules such as protein, peptide and gelatin, have been successfully bound on surface of materials.

plasmaPlasma is one ofthe four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting ofa collection of charged particles, including ions, electrons, and neutral atoms or molecules. Plasma can be found naturally in the universe in the form of stars, lightning, and auroras, but it can also be artificially created and controlled for variousapplicatio
