Ultra-Short Cantilevers (USC)

After the commercialization of Arrow™ UHF since 2014 the NanoWorld R&D team in collaboration with nanotools GmbH started working on the development of a second generation of High Speed Scanning AFM probes called Ultra-Short Cantilevers.

Many different cantilever and tip materials have been investigated and cantilevers with different dimensions have been fabricated and tested.

These investigations resulted in the following basic types:
1) NanoWorld Ultra-Short Cantilevers
Product commercialized by NanoWorld since 2014 with the name Ultra-Short Cantilevers (USC).
During their development phase, these probes were called Ultra-Short New Material Cantilevers (USC-NM).
Also available on demand in a tipless version as NANOSENSORS™ Special Development item.
2) Ultra-Short Silicon Nitride Cantilevers
Available on demand as NANOSENSORS™ Special Development item.

All these probe types feature the same Electron Beam Deposited (EBD) sharp tip manufactured by nanotools GmbH.

This tip is made of High Density Carbon / Diamond Like Carbon (HDC / DLC).

As in High-Speed AFM (HS-AFM) the tip can travel at a speed of a few mm/s in contact with the sample, tip wear becomes a very critical issue.

This problem has been solved by using a HDC / DLC tip which has a Young's modulus eight times higher than Silicon. This results in a much lower tip wear compared to a standard Silicon tip.

Moreover the hydrophobic properties of the HDC / DLC tip enable its use for biological applications where the interactions between the tip and the sample have to be as weak as possible in order to be non-destructive.
