| Outline of Final Research Achievements |
A 500 μm Permalloy wire whose tip was sharpened by electrolytic etching was wound around by an enamel wire with the diameter of 60 μm in a coil shape to form a micro electromagnet, and a needle-like magnetic path type microelectrode was prepared by that its tip was gold-plated to used also as an electrode. In addition, a thin film shaped magnetic path type microelectrode with a thickness of 10 μm was prepared by gold-plating on Permalloy deposited electrically on a chromium patterned by vapor deposition.
By using these two types of magnetic path type microelectrodes, it becomes possible to locally apply a magnetic field and an alternating electric field near its tip, and simultaneous application of magnetophoresis and dielectrophoresis to microparticles in a liquid was succeeded. As this result, specific migration behaviors of maicropaticles affected by magnetophoresis and dielectrophoresis could be observed.
