Abstract

Recently, the cell adhesion phenomenon that occurs in or between cells and other substances has become an important field of research in biology and biomedical engineering. Among the research, the foundational studies primarily experiment using biomedical materials (e.g. Glass Beads) attached to an AFM cantilever. For cell adhesion research, the mechanism where biomedical materials can be attached to the cantilever must be developed for this purpose; however, the mechanism remains an insufficient step. In this paper, a new stage where the Glass Bead can be attached to the cantilever is designed and fabricated;, the mm range movement in the stage is controlled using the stepping motor with a minimum displacement of $1{\mu}m$. The adhesive flow is also controlled using a PZT actuator. In addition, through the air suction, the cantilever holder can be fixed to the stage. The new stage including the bond inflows mechanism is evaluated and analyzed using theory and experiments.
