4 dash-board shaped silicon nitride cantilevers with spring constants suitable for applications like Force Spectroscopy, Force Volume etc. BL-RC150VB cantilevers are Au coated from both sides. The Au coating on the tip side allows users to chemically modify these cantilevers with molecules containing e.g. thiol end groups or other groups strongly binding to gold surfaces. The Au layer is deposited onto an intermediate Cr layer for improved adhesion.t.
