In PeakForce Tapping, the probe periodically taps the sample and the pN-level interaction force is measured directly by the deflection of the cantilever. A real feedback loop (not force trigger) keeps the peak force down to 10 pN at actuation rates up to 8 kHz, in air and fluid.
PeakForce Tapping is ideal for both materials research and biological samples due to its unprecedented low imaging forces and ease of use. No cantilever tuning is necessary. The superior force control maintains tip and sample integrity, leading to consistently accurate and high-resolution measurements of even the smallest structures, from atomic defects to double helix DNA.
The greatest power of PeakForce Tapping technology, however, comes from its ability to simultaneously enable and enhance other correlative and quantitative mapping techniques. It provides new mechanical, electrical, and chemical information on previously inaccessible samples and delivers new possibilities spanning from soft matter to perovskites and energy research.
