Description
炭素は生体に拒否反応がなく、生きている細胞内で起こる生化学的な反応をリアルタイムで測定できる探針として用いられることができる。 この時使われる炭素ナノチューブは、化学気相法により成長した多層壁炭素ナノチューブであり、表面に欠陥(defect)が多くて、多様な機能化が容易である。
炭素ナノチューブは電気伝導度が優れていて、縦横比が高く、電気放出に非常に有用な材料である。特に、レーザー蒸着や電気アーク放電によって作った多層炭素ナノチューブは結晶性が良く、多量の電流を流すことができる。現存する冷陰極タングステンチップ(W tip)に比べて印加電圧が低く、より高い電流を放出でき、放出される電子のエネルギー分布が狭くて電子顕微鏡等の電子銃(electron gun)に応用できる。
縦横比が良好で、狭小な空間に存在する小さな物体に容易に接近でき、柔軟性が飛び抜けていて、試料を損傷せず取り扱うことができる。また、熱処理過程を通した金属及び半導体チップとチューブとの間の接触抵抗を下げることができ、電気伝導度が優れている炭素ナノチューブは試料の電気的特性を研究するにおいて、空間上に存在する非常に狭い線幅を有する電極である。
炭素ナノチューブを原子間力顕微鏡チップに付けて、狭く深い溝を有する試料の地形を容易に分析できる。
