the AFM tip and the other bound to the surface of interest (groups A and B respectively in figure 1). What we refer to as tip functionalization are all the chemical steps that lead to the fixation of molecules A to the AFM tip. The right half of figure 1 shows a typical approach/retract cycle, also called a force-distance curve. First the tip is brought down to the surface until it contacts

Atomic Force Microscopy – AFM (Contact Scanning Mode)

Photoconductive atomic force microscopy (pc-AFM) is particularly prevalent in the development of organic photovoltaic devices (OPV). [12] [45] [46] The fundamental modification of c-AFM to pc-AFM is the addition of an illumination source and an inverted microscope that focuses the laser to a nanometer-scale point directly underneath the conductive AFM tip.

The tip may pick up loose debris from the sample surface. This may be reduced by cleaning the sample with compressed air or N 2 before use. Or the tip can be damaged during scanning, which degrades the images.

A practical guide to AFM force spectroscopy and data analysis

This method of using BOPP to check AFM tips AND to clean contaminated tips was highlighted in April 1, 2001 issue of Analytical Chemistry. 3.2 Applications to blind tip reconstruction Considerable efforts have been expended to mathematically extract the geometry of the tip based solely on an algorithm derived from a given image, which is known as blind reconstruction. This methodology is based

The solution to this is to use the "Tip Check" sample for quick and convenient determination of the AFM tip condition. A single scan is often enough to clearly show the condition of the AFM tip; "Tip check" offers a quick and easy way to compare and categorize different AFM probes with respect to tip parameters like apex, shape and sharpness.
