This work aims to describe about effects of micro-structure on cell selective adhesion. We research to explain the effect through the use of various particles. Polystyrene and silica fine particles are hexagonally packed in 20- 50 μm line-and-space micro-structures for a cell scaffold. An incubation allows most of cells to be successfully adhered on the region of micro-structured particles, while few cells are found on the rest region of glass substrate. Micro-structure composed of 1 μm diameter is effective for selective adhesion in spite of the amount of protein adsorption is equal to 2 μm diameter.
