Exact positioning of single magnetic particles

In the last two chapters several examples for the manipulation of magnetic beads were presented, and bond-force measurements were introduced as an application for the manipulation techniques. This chapter presents the development of special designs to position single magnetic particles at predefined places. This positioning technique will be demonstrated for a special application in the subsequent chapter.

The preparation steps for the samples in this chapter are identical to those for the samples used for the manipulation experiments. Section 3.1 describes the basic processes in detail. The only difference is the used lithographic design.
