Optimal Micromanipulator Design for Gathering Magnetic Beads

Abstract

In this study, we evaluated the optimal geometry for collecting magnetic beads. As a result of making a square shaped coil in the previous research, it was confirmed that magnetic beads were collected at the center and the corner. However, this result was not satisfactory. Because we did not intend for magnetic beads to be collected at the corner of the coil. Therefore, in order to evaluate the shape of the optimal layout, we made and evaluated round, square, and triangular coils, respectively. As a result, it was confirmed that the round coil had the property of collecting magnetic beads in the center more efficiently than the other coils.
