The conformation of cross-linked, monomolecular, polysterene nanoparticles on a solid substrate can be studied with the help of AFM. It’s considered that conformation is a function of cross-linking degree and substrate surface energy. Figure1 shows 4.5x4.5micron image of 4.5-5.5 nm polystyrene nanoparticles and maximum height distribution obtained on shown AFM image is shown in Figure 2

The example of 100nm polymer spheres (Duke Scientific Inc) deposited on m-base substrate shown on Figure3. Image size is 5x5microns.

3-D view of single 100nm diameter sphere (Duke Scientific Inc) of shown on Figure4. Image size is 350-350nm.
