Device and sensor miniaturization has enabled extraordinary functionality and sensitivity enhancements over the last decades while considerably reducing fabrication costs and energy consumption. The traditional materials and process technologies used today will, however, ultimately run into fundamental limitations. Combining large-scale directed assembly methods with highsymmetry low-dimensional carbon nanomaterials is expected to contribute toward overcoming shortcomings of traditional process technologies and pave the way for commercially viable device nanofabrication. The purpose of this article is to review the guided dielectrophoretic integration of individual single-walled carbon nanotube (SWNT)-and graphene-based devices and sensors targeting continuous miniaturization. The review begins by introducing the electrokinetic framework of the dielectrophoretic deposition process, then discusses the importance of high-quality solutions, followed by the site-and type-selective integration of SWNTs and graphene with emphasis on experimental methods, and concludes with an overview of dielectrophoretically assembled devices and sensors to date. The field of dielectrophoretic device integration is filled with opportunities to research emerging materials, bottom-up integration processes, and promising applications. The ultimate goal is to fabricate ultra-small functional devices at high throughput and low costs, which require only minute operation power.

Polarization forces have become of high interest in micro-and nanomechanical systems. In this paper, an analytical model for a transduction scheme based on the Kelvin polarization force is presented. A dielectric beam is actuated by placing it over the gap of two coplanar electrodes. Finite element method simulations are used to characterize the scheme and to evaluate a field correction factor, which results from simplifying the form of the electric field. The model has been shown to be valid for dielectrics with different permittivities. The presented model facilitates the design of microresonators and nanoresonators with dielectric actuation, which offers a great freedom in the choice of structural material.

In the last few years, the creation of new 1D single crystalline molecular materials has attracted much attention due to promising applications in fields such as optics and electronics. [1][2][3][4] Much research effort is currently devoted to obtain long nanowires and nanotubes in a reproducible manner. Most approaches to influence the morphology of nanostructures are based on modifications of the chemical composition of the building blocks and optimization of preparative conditions, such as concentrations, solvents, and temperature. Furthermore, in order to obtain high-quality homogeneous micro-and nanostructures from molecular units in solution, a number of deposition techniques has been developed including zone-casting, self-assembled monolayers (SAMs), Langmuir-Blodgett (LB) films, stamping, electrochemical methods, and thermal evaporation.[5] Although these techniques and their combination facilitate the fabrication of soft-matter devices with low manufacturing costs, large-area coverage on surfaces, and high molecular order, it is still challenging to obtain anisotropic structures and to influence the crystalline structure.Recent studies, however, have indicated that microfluidic systems could provide unique advantages in order to promote the formation of micro-and nanometer-scaled structures. In particular, the formation of crystals and nanoparticles was achieved in microchannels in superior quality due to the excellent handling of small fluid volumes of nano-and even picolitres. [6,7]
