This study reports selective-separation chip complex which can achieve mass throughput by connecting numerous microchip that separate gold nanoparticles by their permittivity using AC dielectrophretic. Dielectrophoresis is an effective technique to manipulate materials in the microchip and has been widely applied for separation of particles or cells. This study proposed a connecting method of microchip and constructed microchip complex. This complex was composed of four parts : the top stage is cross shape chip, the second stage is T-shape chip, the third stage is Y-shape chip and the bottom stage is DEP separation chip. The availability of this connecting method was confirmed by measuring averaged velocity of second stage. Amount of throughput and separation efficiency were measured on DEP separation chip using temporal-spatial averaged PTV.
