A method of measuring a friction coefficient of a surface of a specimen includes: obtaining surface information of the specimen by using an atomic force microscope (AFM); calculating data of a friction coefficient of the surface of the specimen by using the surface information of the specimen; and mapping the data of the friction coefficient of the specimen to an image. The method of measuring a friction coefficient of a surface of a specimen may prevent a probe part of an atomic force microscope from being worn out and secure high reliability of the friction coefficient value by correcting the atomic force microscope using a specimen to be actually measured and measuring a fiction coefficient at the same time.

The presently disclosed subject matter provides systems and methods for generating nanostructures from tribological films. A probe tip can be immersed in a liquid mixture comprising a plurality of ink particles suspended in a medium. A substrate on which the tribological film is to be generated can also be immersed in the liquid mixture. A processor controlling movement of the probe tip can be configured to cause the probe tip to slide along the substrate in a shape of a desired pattern of the nanostructure with a contact force to cause one or more ink particles of the plurality of ink particles compressed underneath the probe tip to be transformed into a tribological film onto the substrate in the shape of the desired pattern of the nanostructure.
