PeakForce Tapping
PeakForce Tapping - to redefine the AFM, 10 years, the future can be period!
Following the launchTappingMode ™Later, brooke unique PeakForce Tapping ® technology has become an atomic force microscope (AFM) is one of the most significant scientific breakthrough.The technology can provide unprecedented high resolution imaging, the AFM measurement to before a series of samples can't be measured, and the sole has realized the nanoscale properties of synchronous measurement imaging.
High resolution imaging
Using PeakForce Tapping technology, the researchers were able to accurately control the probe interaction with the sample, in order to use the smallest force for imaging.This great force control can realize the best consistency, the highest resolution AFM imaging, applicable to from the most soft biological sample to very hard materials such as various types of sample.
No matter, measuring the sample all unique quantitative results can be obtained
PeakForce Tapping technology on the mechanical sensitivity of skin (pN) level, and will be the highest resolution of the AFM imaging and the nanoscale electrical, mechanical, biological and chemical nature of the combined quantitative imaging, help make new researchers found different levels of experience.
Outstanding ease of use, each user become experts AFM
PeakForce Tapping technology for direct force control, linear, with the help of a ScanAsyst ® intelligent optimization technology greatly simplifies the AFM.The minimum force required to imaging can keep the shape of probe, so as to prolong the service life and realize the consistency of better imaging.
The working principle of
In PeakForce Tapping mode, the probe samples periodically touch, touch the leather cow level (pN) interaction force can be directly by the bending of the beam is measured.A feedback loop (not load trigger) working principle,Can stay in the air and liquid environment reduced to 10 pN peak force, operating frequency can be as high as 8 kHz.
PeakForce Tapping in low imaging unparalleled strength and ease of use aspect, is the ideal choice of the materials research and biological samples.The need for cantilever beam tuning.Great force control can maintain the integrity of the tip and the sample, ensure that always can get precise measurement results, high resolution, even if the sample is one of the most subtle structure (for example, from the atomic defect and the DNA double helix structure).
Support PeakForce Tapping mode of AFM
PeakForce Tapping of the biggest highlights of the technology is the ability to synchronize enabled and reinforced material properties associated with quantitative imaging, for constant expansion at the nanoscale morphology, mechanics, biology, electricity and chemical application provides a new possibility:
- PeakForce QNM ®- quantitative characterization of nanoscale mechanics
- PeakForce TUNA ®- for the most vulnerable samples current of high resolution imaging
- PeakForce KPFM- leading the spatial resolution and contrast without artifact
- PeakForce Capture- each pixel with high sensitivity nano mechanics data
- PeakForce SECM- based on AFM scanning electrochemical microscopy
- PeakForce sMIM- the most sensitive and the most comprehensive nanoscale dielectric constant and conductivity imaging
The most popular mode of AFM
Since the advent of PeakForce Tapping frequency of use even more than the Tapping mode.Ten years, the use of this technology has been more than 4000 articles published.Among them, based on PeakForce QNM technology more than 2000 articles, more than 400 articles based on the pattern of PeakForce electrical.This means that, at least once a day since 10 years to launch a paper based on the Peak Force of Tapping technology article!
