Calibration Service for AFM Cantilevers

The NANOSENSORS screencast on the calibration service for AFM cantilevers has just reached the 500 views mark

Accurately determined cantilever properties are very important for quantitative force measurements. Force constant and resonance frequency are determined either by thermal tune, the Sader- or the dimensional method, respectively. Usually, the thermal tune method delivers the most precise values, but suffers from the fact that the AFM tip has to get in contact with the surface to calibrate the photo-detector sensitivity. This procedure may damage or break the tip!

NANOSENSORS™ offers a thermal tune calibration procedure performed by Laser vibrometry. This method is contact free and therefore does no damage the tip, but preserves the original AFM tip quality. To ensure the highest level of accuracy NANOSENSORS™ cantilever calibration method is calibrated with a standard, certified by the national German metrology institute.

This service is part of our Special Development List.

Spike up a Silicon Nitride AFM tip for high topography biology and life science imaging

Standard SiN AFM probes may have a lot of advantages for using them in your liquid cell measurements. But they also have their limits when it comes to high topographies on cells or other bio samples due to their relatively wide opening angle and the small 3µm tip height.

By teaming up with nanotools in Germany NANOSENSORS is able to offer you a “spiked-up” AFM tip – a silicon nitride probe with a long (10 µm) spike made of high density carbon grown on top of it – called Biotool XXL.

Customized versions such as other tip lengths or other cantilevers are also possible.
