Abstract

　ＣＮＴ－ＦＥＴバイオセンサ装置１は、ソース－ドレイン間にカーボンナノチューブ（ＣＮＴ）を形成したカーボンナノチューブ電界効果トランジスタ（ＣＮＴ－ＦＥＴ）でなるセンサヘッド２と、濃度が未知の蛋白質又はＤＮＡを測定して得られた上記センサヘッド２の出力値から上記蛋白質又はＤＮＡの濃度値を演算する演算部３とを備える。上記演算部３は、濃度の変化に対して同一出力しか得られない濃度の上記蛋白質又はＤＮＡを予め測定して得られた上記センサヘッド２の出力値を記憶する記憶部３０を備え、上記記憶部３０に記憶された出力値を用いて、上記センサヘッド２の出力値を校正して、上記蛋白質又はＤＮＡの濃度値を演算する。
