The present paper determines static and dynamic friction forces and friction coefficients using atomic force microscope during the hydrodynamic viscoelastic liquid flow in the thin boundary layer around the cells of two cooperating bodies. Atomic force microscope is necessary in performed experimental investigations and measurements of friction forces. Therefore, proper parameters of microscope are described and illustrated in specific enlargement. The use of microscope of atomic forces AFM for complex technical investigations to a large extent has facilitated carrying-out the measurements of tissue surface features and control of its growing process in human joint and deforming process in micro-bearing alloy. During conventional nano-scale measurements of surface topography, the AFM microscope makes it possible to simultaneously map local lateral forces and oscillatory phases of translations, which may be interpreted as a representation of local friction forces and local adhesive forces as well as values of elasticity modules. One of the important advantages of the AFM microscope application in the area of investigations with the use of bio-reactors is the possibility of carrying out measurements directly in liquid, namely that surrounds the cells or micro-bearing gaps
