POLY 462 |
| We report imaging of synthetic polymer single molecules under aqueous media using atomic force microscopy (AFM). AFM is the only existing method for the detailed 3D visualization of real adsorbed polymer chains. We discuss applications of AFM for in situ visualization of the conformation details of molecules and the location of the molecule placement on the surface, direct measurement of the molecular characteristics of real adsorbed polymer molecules, and study of their motion dynamics on the surface. The discussed examples include 0.4 nm thick poly(2-vinylpyridine) chains in adsorbed state at mica-liquid interface and varying parameters: scanning force, pH, and ionic strength. |
