Scanning force microscopy (SFM) is the only tool that allows one to image S-layer protein monolayers on solid supports at molecular resolution (Fig. lb and c) [22-25]. In particular, SFM in contact mode under water with loading forces in the range of <500 pN leads to an image resolution in the subnanometer range (0.5-1.0 nm).

For many reasons, the tapping mode is one of the most versatile developments in scanning force microscopy [ 114]. It was originally introduced for stable imaging at ambient conditions as the probe penetrates the contamination layer rapidly and intermittently. Besides that, there are three other key advantages of...

Figure 17.7 Scanning force microscopy images taken in non-contact mode for neat C o and CuPc films as well as for three mixed films grown at 375 K. The total image size is 2 x 2 pm. The max. height is given as the difference between the lowest value (dark blue) and the highest value (white) in each of the images.

Abstract In this review, we show the distribution of glass transition temperature (Tg) in monodisperse polystyrene (PS) films coated on silicon oxide layers along the direction normal to the surface. Scanning force microscopy with a lateral force mode revealed that surface T (Tl) was lower than the corresponding bulk T, (T ). 

As an analytical tool for such a chemically patterned SAM surface, pulsed-force-mode atomic force microscopy (PFM-AFM) designed by Marti and coworkers [349] is useful as scanning force microscopy with chemical recognition capability [350, 351] (see chemical force...

Within the numerous proximal probe techniques developed in the years following the breakthrough inventions of the STM (1) and AFM (5), scanning force microscopy (8) represents a family of scanning probe techniques that rely in their contrast mechanism on various forces between probe tip and sample (9-12) (see Atomic Force Microscopy). In order to provide a basis for an understanding and appreciation of the SFM work on polymers (13-18), as presented in this review, the basic principles of SFM, as well as selected imaging modes, are briefly discussed.
