message: I think most AFM's (I know of, anyway) use the laser reflection detection method.  Feel free to put back the interferometry if I'm wrong.
RE:
Added some other possible detection methods. Although laser reflection is most common, things like interferometry, piezo-levers etc. are used as well in some (and growing) applications -- PMH, July 7,  2006
The original AFM as built by Binnig &co had an STM on the back to detect lever deflection. I think a few groups now are developing MEMS based levers for more accurate detection of deflection (although I can see this approach creating new problems the optical lever approach doesn't have). DJ
:I fail to see how a longer cantilever amplifies changes in the beam angle. The cantilever would have to be extended beyond the scanning tip in order to amplify changes in the beam position (but not angle). Icek (talk) 18:28, 8 November 2010 (UTC)

message: I tried to make the section on imaging modes more self-consistent using my experience with AFM and the already provided information. This section still needs a lot of work.

message: Also, I think tapping mode is a trademark of DI/Veeco, but I'm not sure if it's "tapping mode" in general or "TappingMode" which they've got on their website - if someone is better informed, fill me in. --Bibble 13:58, 27 Jul 2004 (UTC)
thread_title:  Tapping Mode 

message: I edited this section because it was too specific in that it focused NC-AFM around surfaces with adsorbed liquid only. My corrections were intended to generalize the description of NC-AFM and expand on NC-AFM as it applies to surfaces with adsorbed liquid. Jatosado (talk) 02:20, 7 April 2009 (UTC)

message: Perhaps there should be a little more info on the ability for using AFM's for manipulation, for example nanolithography, or for moving around and cutting up large molecules like DNA?

message: In the article cited for biological utility for AFM (citation 11) at no point is there any discussion of protein-ligand interactions.

message: Nearly four years ago, the popular media published this nice image of pentacene:  http://www.dailymail.co.uk/sciencetech/article-1209726/Single-molecule-million-times-smaller-grain-sand-pictured-time.html   "'This is the first time that all the atoms in a molecule have been imaged,' lead researcher Leo Gross said."
By now, shouldn't we have seen many more (and/or higher-quality) images of molecules?  The lack of additional images makes me wonder whether the first image was a hoax. 174.24.17.119 (talk) 14:41, 21 January 2013 (UTC)

text: I second this. I have seen images through a real atomic force microscope in first year, but where are all the images? I'm searching all over the internet and I'm disappointed in the lack of images of everything. ugh [EDIT: found this http://nano.em.keysight.com/index.php/image-library] 24.141.2.226 (talk) 00:21, 24 December 2015 (UTC)

thread_title:  Primary Image Caption Reads as though it's an Advertisement 

message: Noncontact AFM is a bit of a misnomer and the use of this term to describe an AFM mode for imaging topography in scientific literature has lost popularity in the past 5 or so years.  It is more common to describe AFM modes for topographic imaging in in terms of the applied feedback mechanism  i.e. Contact Mode AFM, Amplitude Modulation AFM, and Frequency Modulation AFM as opposed to Contact Mode, Tapping Mode, and Noncontact mode.  I think the adjusted terminology should be applied to the article.  — Preceding unsigned comment added by 128.211.178.4 (talk) 06:41, 26 February 2014 (UTC)

thread_title:  External links modified 

message: As a present for his 70th birthday, my father, Martijn Katan, asked me to edit a Wikipedia page. I naturally turned to the thing I know most about, the Atomic Force Microscope. As someone with 14 years of experience in using, designing and modifying AFMs, I see a lot of things wrong with this page. The structure is very confusing, some things are explained five times and others are completely left out. E.g. the fast force mapping methods that are becoming popular now are not even mentioned, even old school force volume is not in there. The strong link between AFM and many other SPM techniques like KPFM, SSRM, PFM etc is not clear. The list of applications is extremely limited. There are hardly any AFM images to illustrate the capabilities. The list goes on.
:I have started doing a major overhaul, but I don't want to rewrite this whole page on my own, as this is not what Wikipedia is about. So I call on any AFM experts that read this page to help me improve it.Allardkatan (talk) 00:23, 12 February 2016 (UTC)
thread_title:  This article needs updating and improving 

message: When people move little groups of atoms together with software control, what is the velocity of that process?  
The article does not yet say.  I wrote a thing suggesting a little clump of atoms could be constructed every 1/10 of a second, (basically,on a platter put grouped atoms together that might form a superconductor with afm, then laser warm them to crystallize, then rotate the platter like a disk drive to detect meissner effect variations at a number of temperatures to find new superconductors, 1/10 of a second sample prep is 300 million samples a year)  — Preceding unsigned comment added by 68.185.2.34 (talk) 17:26, 30 August 2012 (UTC)
replies: text: Imaging is not the same as nanomanipulation. Moving a single atom over a few nm takes only a fraction of a second. However, preparing a surface such that you have the atoms you want in place, identifying the different atoms and figuring out how and where to move them can take anything between days and years.Allardkatan (talk) 00:06, 12 February 2016 (UTC)

Where does the year 1982 come from? Most articles I have seen attribute its invention to the year 1986, and there is nothing in the cited article referencing the stated year.  — Preceding unsigned comment added by Cachinnus (talk • contribs) 03:54, 24 November 2017 (UTC)
