AFM Study of Surface Derivatization for Biosensors

 

Study of Quartz Beads

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.
