Title:
ELECTROPHORETIC CHIP, ELECTROPHORETIC DEVICE, AND ELECTROPHORETIC SYSTEM
Document Type and Number:
WIPO Patent Application WO/2007/046485
Kind Code:
A1
Abstract:
An electrophoretic panel (10) causes a dielectric substance to migrate dielectrically
by applying an electric field generated by an AC voltage, to a sample containing
the dielectric substance. The electrophoretic panel (10) is equipped with migration
lanes (3) for causing the dielectric substance to migrate dielectrically, and
a migration electrode array (6), which includes a plurality of migration electrodes
(6a) intersecting with the migration lanes (3) and which causes the dielectric
substance to migrate dielectrically by applying the AC voltage so as to apply
the electric field to the sample injected into the migration lanes (3). These
migration lanes (3) are transparent at their faces confronting the migration
electrode array (6) at least partially of the areas, in which the migration lanes
(3) and the migration electrode array (6) are superposed. In the migration electrode
array (6), moreover, the migration electrodes (6a) are made of transparent electrodes
at least partially of the migration electrodes (6a) at their portions superposed
on the transparent areas of the migration lanes (3).
