“…Thus, it is possible to obtain a reasonably good approximation of the effect of this force by keeping only the integration over parts of the surface of the body that faces the plane. It should be noted that the importance of the SIA approach has been already recognized and used; see, e.g., [ 87 , 88 , 89 , 90 , 91 , 92 ]. For the QED Casimir force, such a generalization has been derived on the solid basis of quantum field theory in the framework of scattering approaches (see, e.g., [ 93 , 94 ]).…”

Fluctuations are omnipresent; they exist in any matter, due either to its quantum nature or to its nonzero temperature. In the current review, we briefly cover the quantum electrodynamic Casimir (QED) force as well as the critical Casimir (CC) and Helmholtz (HF) forces. In the QED case, the medium is usually a vacuum and the massless excitations are photons, while in the CC and HF cases the medium is usually a critical or correlated fluid and the fluctuations of the order parameter are the cause of the force between the macroscopic or mesoscopic bodies immersed in it. We discuss the importance of the presented results for nanotechnology, especially for devising and assembling micro- or nano-scale systems. Several important problems for nanotechnology following from the currently available experimental findings are spelled out, and possible strategies for overcoming them are sketched. Regarding the example of HF, we explicitly demonstrate that when a given integral quantity characterizing the fluid is conserved, it has an essential influence on the behavior of the corresponding fluctuation-induced force.
