摘要: Abstract Surface forces determine the behaviour and properties of colloids, including biological molecules, micelles membranes. Recently it has been realized that atomic force microscope, which is normally used to image topography surfaces with high resolution, can also be measure surface forces. The advantages microscope are virtually any interest investigated measurements relatively fast easy perform. Furthermore, since interacting areas small (typically 10 2 –100 nm ) samples only need smooth homogeneous on a scale. Local properties, like charge density or micromechemical determined.
