Modification of the tissue-culture polystyrene (TCPS) surface by the silver-negative-ion implantation was investigated with respect to contact angle, selective cell attachment properties and control of cell orientation. Negative-silver ions were implanted into TCPS at a condition in energy and dose region : 5-30 keV and 1 × 10<SUP>14</SUP>-1 × 10<SUP>16</SUP> ions/cm<SUP>2</SUP>. By this implantation, the surface of TCPS was changed to be hydrophobic, and loosed its cell attachment property. In the patterned implantation through a mask with slits of 40 μm-wide and 4 mm-long with a spacing of 40 μm, the cells attached on the unimplanted region of TCPS. In addition, most of the attached cells aligned along a stripe pattern.
