Description
前記制御装置により、前記振動子の前記探針位置を周期的に変位させるとともに、前記探針位置と前記探針に印加する交流電圧のタイミングを制御して培養液中の静電場分布計測の感度を最適化することを特徴とするものである。
神経シグナルの測定においては、試料3の表面と探針1の先端の距離を常に一定に保ちながら行う。神経シグナルは、電荷注入電極56により神経細胞に電荷を注入することにより神経細胞に生ずる電圧パルスである。神経シグナルの測定には、まず試料3に対して所定の電荷を注入することにより神経細胞に電圧パルスを印加する。このとき、電圧パルスの大きさは50μV〜100mV程度である。試料3の所望の位置に探針3を接触、または、接近させ、この電圧パルスを実施例5の走査プローブ顕微鏡により検出する。試料3の多点において電圧パルス計測を行い神経シグナルが伝達されているかを判断することにより、培養された神経細胞の不良箇所を特定することができる。
