Surface coating

Patent Granted A surface coating comprises a primer coat that permits adhesion of eukaryotic cells thereto, and a plurality of macromolecular structures attached to the primer coat. At least some of the macromolecular structures have a cell-resistant character, meaning that cells generally will not adhere to them. The macromolecular structures are distributed across an area of the primer coat so that the surface coating permits adhesion of the eukaryotic cells to the primer layer and resists the adhesion of non-eukaryotic cells.
