CHEMICALLY SPECIAL SURFACE FOR IMPARTING INFLUENCE TO CELL ACTIVITY DURING CULTURE

摘要

CHEMICALLY SPECIFIC SURFACES FOR INFLUENCINGCELL ACTIVITY DURING CULTUREABSTRACT OF THE DISCLOSURECell culture activity on the surface of thesubstrate is influenced by varying surfaces incontact with the cell membrane. In particular,plasma modification processes are used to providespecific chemical functional groups, elementalratios and other surface properties. In themethod of the invention for influencing the growthof cell culture in a growth media on a substrate,the surface chemistry of the substrate is modifiedby subjecting the surface of the substrate to aplasma which is produced from a material selectedfrom the group consisting of carbon, hydrogen,osygen, nitrogen, sulfur, phosphorus, halogens andcompounds thereof.
