Nanomechanics = biomechanics

The knowledge of the mechanism of mechanical energy production by the so-called bioengines, living cells, could be very helpful for resolving different tasks concerning nanomechanics, e.g., construction of nanorobots. The present work considers a new idea, namely that the conformational changes within the so-called track, actin filament or microtubule are crucial for production of the mechanical energy by all bioengines. This concept contrasts with the presently prevailing view, according to which the force is generated as a result of conformational changes within the so-called motor proteins: myosin, kinesin or dynein.
