Abstract :
For the various nano-fluidic based biomedical applications, the study of the drag of fluid flow is of interest. Among which, the study of boundary slip is one of the most important and popular issues. Hydrophobic surfaces, which are believed to have a slip length, play an important role in the fluidic applications. There are various methods to measure slip length on hydrophobic surface. This paper induces an improved method based on atomic force microscope (AFM) in contact mode.
