概要
- 論文の詳細を見る
We report a simple new method to improve the cell adhesion ability on the Si_3N_4 surface. Light-addressable potentiometric sensors(LAPS)have become a powerful tool for studying the biological action of cells. The Si_3N_4 surface of a LAPS structure was coated with poly-L-ornithine and laminin to improve its cell adhesion ability. The thickness of the coated layer was very thin, about 4 nm, as determined by atomic force microscopy measurement and thus this treatment surface is suitable for biological sensing applications such as the detection of cell activities.
