requimte pageThere is a new page here, which is about the recently set up AFM labs in my research institute, Requimte. The page has location, booking information, etc about the labs. But it also has operation protocols for the instruments, so might also be of use for other users of the TTAFM from AFMWorkshop. There are also some example images collected on the two machines, on their individal pages, Long Beach and Signal Hill. The page can be reached directly at

The Requimte AFM Training Workshop will run during Easter 2014, from the 14th to 17th April. Following the successful courses that ran in 2011 and 2013, we've decided the course should run annually. The course includes several hours hands-on training in acquiring images with the atomic force microscope as well as AFM data processing. The course has been reorganised based on student feedback, and will feature advanced topics lectures from guest scientists in biology and materials science. This year, we plan to lengthen the practical part of the course, and hope to offer access to different instruments.


  • We are pleased to announce that this year, there will be 3 invited speakers, covering applications in a wide range of areas, and illustrating different capabilities of AFM:

Dr. Rui Rocha, CEMUP, Porto: "Materials Applications of AFM"

Dr. Simon Connell, University of Leeds, UK: "Dynamics in Biological AFM"

Dr. Filomena Carvalho, IMM, University of Lisbon, "Force Spectroscopy: Biological and Biomedical Applications"

Thanks to all the speakers for agreeing to talk.

  • The provisional timetable can be downloaded here.
  • There is a document containing in formation on travel to Porto, and hotels near the faculty of sciences here.
  • The 2014 course has had all 16 places filled.
  • The course flyer can be seen by clicking below: 



 A blog with information and student feedback from the 2013 course can be seen here: Requimte AFM Workshop 2013

 Some information about the course that took place in 2011 can be seen here:

The course is sponsored by AFMWorkshop. It is also supported by The University of Porto, and will be integrated into the forthcoming network BIO-AFM.


In our lab, we have a TT-AFM, and an LS-AFM from AFM Workshop. We had one of the very first examples of this microscope, so although it's fairly new, the instrument, and the software has developed a lot during that time. On this page, I have collected together various materials that can help use the TT-AFM instrument. Note that although this material is all based on the TT-AFM, a lot of it probably applies to the other instruments from AFM Workshop, since they are all based on the same electronics. Lots of more general information about AFM operation can be found around this website (links on the left), and of course in my book.


 Some images from the TT-AFM obtained in our lab showing gold nanospheres, gold nanotriangles (phase image), tobacco mosaic virus, and Quantum Dots (2 nm).

 UPDATE: The latest version of the AFM Workshop software 2.03, seems to be far superior to 1.58, which I was using previously. I reccommend strongly that everyone check this version out.


This page contains currently a very small selection of the AFM images I have collected over the years. Please check back later to see more.

group shot 2a l"I really enjoyed my time on the course. In a simple and practical manner, I learned how to obtain results from AFM. I entered the course without ever being on the same lab with an AFM and left being able to carry out an experiment and analysing my own results."


Last week, we held our AFM workshop for 2013, here in Porto. We had students from Portugal, Spain, Germany, Romania, Denmark and Norway.
The students enjoyed the course a lot, and we got lots of very positive feedback.

"I have to tell you that I'm enjoying a lot this mini-course. The language used to explain the concepts is very clear and there is a good atmosphere between all participants."
This is the second time we've run the course, and the first time in Porto. Last time we ran it in Lisbon. We brought one AFM up from our lab in Lisbon, so the students had access to two instruments.
tobbacco mosaic virusOn the first day, after meeting the students, we started with a short introduction to AFM, followed by a talk about AFM instrumentation, focussing on important concepts, and the differences between different instruments the students might encounter. Some of the students were already using AFM, and some had never used it. In fact, a couple of the students were already regular AFM users, but still found the course useful: 
"I found it useful even for people (like me) having a certain experience in the field. For instance, things that work well in/with AFM can be easily found in a lot of papers, but things that are hard or tricky to set up are seldom explicitly written in articles. The workshop addressed specifically this type of issues. Also, to my opinion, attending the workshop was not expensive at all. "
