Patent ID: 7082683

Claim:
A method for manufacturing a probe for signal detection having a rod-shaped nano structure attached thereto, the method comprising the steps of: disposing an electrode, and disposing one end of a holder to a supporter such that the holder protrudes towards the electrode wherein a predetermined distance remains between the end of the holder and the electrode; supplying a solution between the holder and the electrode at a second predetermined distance, such that space between the holder and the electrode is filled with the solution, wherein a rod-shaped nano structure is dispersed in the solution; and applying a voltage including alternating current (AC) voltage to the holder and the electrode such that the rod-shaped nano structure is attached to the the end of the holder by dielectrophoretic force caused by a non-uniform electric force formed between the holder and the electrode; and evaporating the solution while maintaining the predetermined distance between the electrode and the end of the holder.
