| Research Abstract |
Frequency-modulation atomic force microscopy (FM-AFM) is a promising tool to observe the solid topography and the liquid structure at interfaces. The cantilever with a tip is resonantly oscillated and the shift of the resonance frequency represents liquid-induced force pushing or pulling the tip. We have successfully examined a number of liquid-solid interfaces including water/mica, water/TiO_2, water/Al_2O_3, water/hydrophilic self-assembled monolayers, alkanes/hydrophobic monolayers, water/p-nitroaniline crystal, water/peptide nanotubes. The observed, two-dimensional distributions of tip-surface force were sensitive to the composition of the solid and liquid, while insensitive to tips of different apex radii. This suggests that the observed force distribution was not much affected by the presence of the tip above the interface.
