A novel cell-adhesion surface, controlled by nanometer-scale topography and chemical patterning, was developed using semiconductor fabrication methods and the formation of self-assembled monolayers. The patterned surface had a sharp contrast between the adsorption and non-adsorption of proteins and cells, and the contrast could be maintained for more than 10 days. The patterning method could easily realize a single cell array and control of the cell morphology. The nanometer-scale patterned surface could control cell adhesion and proliferation. Using the patterned surface will contribute to studies about cell-surface interactions.
