NanoWorld AG has announced the official commercialization of six types of Ultra-Short Cantilevers (USC) dedicated for use in High-Speed Atomic Force Microscopy (HS-AFM).

High Speed Atomic Force Microscopy is a quickly evolving technique within the field of Scanning Probe Microscopy that enables the users of dedicated instruments and AFM probes to visualize dynamic processes at the single molecule level.

After a very successful beta-testing phase six types of AFM probes for high speed scanning will be commercially available from now on.

In order to provide a suitable probe for the complete range of high speed scanning applications, the Ultra-Short Cantilevers series consist of six different types of AFM probes divided in 2 categories.

Three types of Ultra-Short Cantilevers with very high resonance frequencies (1.2 MHz - 5 MHz) and high force constants are mainly meant for use in dynamic mode applications in air.

• USC-F2-k3 http://www.nanoworld.com/Ultra-Short-Cantilevers-USC-F2-k3.html
• USC-F1.2-k7.3 http://www.nanoworld.com/Ultra-Short-Cantilevers-USC-F1.2-k7.3.html

Three further types of Ultra-Short Cantilevers with high resonance frequencies and low force constants (0.6 N/m - 0.15 N/m) are mainly dedicated for applications in liquid.

• USC-F1.5-k0.6 http://www.nanoworld.com/Ultra-Short-Cantilevers-USC-F1.5-k0.6.html
• USC-F1.2-k0.15 http://www.nanoworld.com/Ultra-Short-Cantilevers-USC-F1.2-k0.15.html
• USC-F0.3-k0.3 http://www.nanoworld.com/Ultra-Short-Cantilevers-USC-F0.3-k0.3.html

All AFM probes of the USC type feature a wear resistant tip made from High Density Carbon/Diamond Like Carbon (HDC/DLC) with a typical tip height of 2.5 µm and a radius of curvature typically < 10 nm.The aspect ratio is typically 5:1 and the tilt compensation is 8°.

The cantilevers are coated with gold on both sides but the tip remains uncoated.
