Multifrequency AFM Tutorial, October 15 Madrid, Spain


Multifrequency AFM Tutorial, October 15
  Madrid, Spain

Contact resonanceThe need for higher compositional resolution and sensitivity has led to exploration of imaging with higher harmonics and/or flexural or torsional cantilever modes.  More recently, the AFM is experiencing the evolution from single to multifrequency excitation and detection schemes.

The Multifrequency AFM Tutorial will be held October 15th in conjunction with the 4th Multifrequency AFM Conference, covering a variety of topics by leading researchers in the field.   Demonstration on the Cypher™ AFM will occur after the lectures.


9:00am    Introduction to Multifrequency AFM

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at

Dr. András Paszternák, founder of Nanopaprika
