Estimating the term…
A cell adhesive material with excellent cell adhesion and cell proliferating property and a method for producing the same are provided. The adhesion and proliferation of cells can be improved remarkably by the surface modification of a cell adhesive material comprising a polymer material containing carbon as a constituting element, such as polystyrene or segmented polyurethane, wherein at least a part of the surface is modified by ion bombardment through ion implantation. The method for producing such cell adhesive material comprises implanting ions into at least a part of the surface of the polymer material. The cell adhesive material and the method for producing the same are promising for application to cell culture petri dishes and hybrid-type medicinal materials.
A cell adhesive material comprising a polymer material containing carbon as a constituting element, the polymer having a surface which has been modified by ions implanted into the polymer surface by ion bombardment thereby causing cells to adhere to the modified surface.
A method for producing a cell adhesive material, comprising implanting ions in a range of 1.times.10.sup.15 .ltoreq..phi.<1.times.10.sup.18 ions/cm.sup.2 into at least a part of the surface of a polymer material containing carbon as a constituting element.
