UPDATE: The site has been upgraded to new back-end code. This should help stability and enable new features in the future. Hopefully all the old pages are working now on the new code. If you see any problems, let me know!

The design of the site was changed a little, it looks kind of plain now, maybe I'll revert to the old look later. 

There is now a new AFM Image Gallery, which contains more images than before, organised in categories and a few by instrument.

Many people have asked me for a copy of this simple figure, showing how the AFM works. It's available for download below as a high quality .ppt file.

As discussed in the appendices A and B of my book, reference and calibration samples are extremely important for AFM. Calibration samples allow the AFM to make accurate, quantitative measurements. Reference samples can be used for training, and certification, and just to check if the instrument (or the probe) are performing as they should. There's a list of commercially available calibration and reference samples here.

AFM piezoelectric scanners tend to change their responses and age over time, so it's necessary they they be recalibrated periodically (typically annually).  All these repeated uses can lead to reference samples becoming dirty and contaminated. This leads to serious problems, because a contaminated samples cannot be properly used for calibration of an instrument, and may also be difficult to use as a reference sample. The article below explains some techniques that can be used to clean AFM calibration and reference samples. Note that this method o sample cleaning first appeared at AFMWorkshop.com. I learned the "NewSkin" method while visiting their headquarters.

The deadline for our 2015 AFM training workshop has passed, and we cannot take any more registrations. If you want to be informed when the next course is announced, email me. For more details about the courses click here, or download the flyer below.

I am going to be teaching on two new AFM short courses to be held this summer. The courses are:

AFM Advanced Operation Techniques

and

AFM Bioapplications

Both of these courses will be taught at the headquarters of AFMWorkshop in California, USA, but will be open to, and suitable for, users of all instruments. The courses will be a mix of lectures and practical work with different microscopes.

Both courses are taking place in mid-July. Follow this link to a .pdf brochure, and consult the AFM Workshop website for more details on these courses.

At the time of writing there are places available on both courses, but places will be very limited. I recommend reserving a place ASAP from AFMWorkshop, if you are interested.
