Description
(実施例1)
図7に実施例に用いた細胞融合用微小流路構造体を構成する基板(13)の概念図を示した。細胞融合用微小流路の形状は微小流路(30)と連通した細胞懸濁液の導入流路(40)と細胞懸濁液の排出流路(41)がそれぞれY字状に2本に分岐している。また、微小流路内には微小流路の幅に対してほぼ中央の位置に隔壁(8)を形成した。また、Y字状の細胞懸濁液の導入流路と排出流路が微小流路と接続される部分の4箇所に幅10μm、高さ50μmの凸部(34)を形成した。また、導電部材によりなる平板電極の一つの縁を凸部の微小流路の外側部分に密着させて平板電極を設置できるような長さ36mm、幅25mm、深さ50μmの凹部(37)を微小流路基板上に形成した。なお、隔壁、凸部、凹部は基板(13)と一体形成した。図8には、図7における基板のA−A’断面図を示した。また図9には、図7におけるB−B’断面図を示した。微小流路の幅(18)は100μm、微小流路の深さ(19)は50μm、微小流路の長さ(42)は30mmである。微小流路内に基板とともに一体形成した隔壁には、間隙と間隙の間隔(33)を50μmとし、感激を300個形成した。間隙の長さ(20)は50μmとし、隔壁の中心幅(21)は10μm、隔壁の高さ(43)は50μmとした。
