“…If, in an attempt to release the particle, one charges the particle, forces vibration of the surface in question, etc., the released particle might move in an uncontrollable way leaving the observation field of the apparatus controlling the performance of the operation. That is the main reason why the handling, feeding, trapping and fixing of micro-and/or nano-particles is still the main bottleneck in micro manufacturing and is far from being solved in a satisfactory fashion [26]. Thus, formalizing the above, one of the main problems in the micro-and nanoassembly is the precise and reliable manipulation of a microor nano-particles that includes moving it from a given starting point, where it is to be taken from, to some end point, when it is to be placed on.…”

We study systems in which both long-ranged van der Waals and critical Casimir interactions are present. The last arise as an effective force between bodies when immersed in a near-critical medium, say a nonpolar onecomponent fluid or a binary liquid mixture. They are due to the fact that the presence of the bodies modifies the order parameter profile of the medium between them as well as the spectrum of its allowed fluctuations. We study the interplay between these forces, as well as the total force (TF) between a spherical colloid particle and a thick planar slab, and between two spherical colloid particles. We do that using general scaling arguments and mean-field type calculations utilizing the Derjaguin and the surface integration approaches. They both are based on data of the forces between two parallel slabs separated at a distance L from each other, confining the fluctuating fluid medium characterized by its temperature T and chemical potential µ. The surfaces of the colloid particles and the slab are coated by thin layers exerting strong preference to the liquid phase of the fluid, or one of the components of the mixture, modeled by strong adsorbing local surface potentials, ensuring the socalled (+, +) boundary conditions. On the other hand, the core region of the slab and the particles, influence the fluid by long-ranged competing dispersion potentials. We demonstrate that for a suitable set of colloids-fluid, slab-fluid, and fluid-fluid coupling parameters the competition between the effects due to the coatings and the core regions of the objects involved result, when one changes T , µ or L, in sign change of the Casimir force (CF) and the TF acting between the colloid and the slab, as well as between the colloids. This can be used for governing the behavior of objects, say colloidal particles, at small distances, say in colloid suspensions for preventing flocculation. It can also provide a strategy for solving problems with handling, feeding, trapping and fixing of microparts in nanotechnology. Data for specific substances in support of the experimental feasibility of the theoretically predicted behavior of the CF and TF have been also presented.

“…Adhesive forces hold particles firmly on a carrier, irrespective of their arrangement. In contrast to handling particles using aspirating nozzles, or electric or magnetic forces, [16] adhesion is a robust and technically simple approach that is compatible with very small particles. Well-defined particle surfaces allow the creation of an adhesion cascade, such that particles can be transferred from surface to surface, exploiting the increasing adhesion.…”

Closing the Gap Between Self‐Assembly and Microsystems Using Self‐Assembly, Transfer, and Integration of Particles

Self‐assembly, transfer, and integration of particles is achieved by combining self‐assembly processes with an adhesion cascade (see Figure). This process complements and enhances existing fabrication methods as it allows the integration of particles into planar devices. Moreover, it is versatile in terms of particle size and materials, and can create arbitrary particle arrangements with functional particle–substrate connections.
