Details

Gold deposited silicon nitride cantilevers for DC (contact) mode AFM and LFM

Cantilever
TR400PB composes two pairs of different shapes of triangular cantilevers protrude from both sides of a glass chip.

Tip
The pyramidal tip is sharpened toward the tip apex. The tip has an uneven surface due to the gold cluster.
• Tip shape : sharpened square pyramidal (hollow tip)
• Tip height : 2.9 µm
• Tip radius : less than 30 nm
• Tip angle (face to face) : 25 - 45 deg. (top to around 300nm down)
• Tip material : Gold coated silicon nitride

Metal reflex coating
Thin gold/chromium film is coated on the back side of the cantilevers for reflecting light from a deflection sensor in the AFM equipment.

Tip coating
Thin gold/chromium film coating on the tip side of the cantilevers makes functionalizing the tip easier (e.g., using thiol chemistry)

Applications
• Contact mode AFM
• Silicon nitride tips sometimes stick to sample made of silicon nitride during the scanning. Gold coating works as a solid lubricant to avoiding this.
• Contact probing of IC devices
• For functionalizing tip surface with -SH base and -NH2 base
These gold coated tips are recommended because utilizing gold for this purpose is a very familiar protocol among biologists and chemists. In force curve analysis to estimate a binding force between molecules, the functionalized tip is often used.
