Quartz beads used in this study were prepared at the end of a fused
quartz rod and mounted in the AFM instrument with a magnetic holder.
The configuration of the holder is illustrated below.
After the quartz bead holder is mounted in the AFM microscope, the
AFM probe is then positioned over the top of the glass bead. The
following image displays the cantilever being positioned over the
quartz bead.
