“…Graphene oxides combining with the excellent properties of neat graphene, rich surface functional groups and low cost, are expected to be promising nano-scale filler for the next generation of functional composite materials [14]. Until recently, tribological studies on graphene preliminarily focus on the microscopic study of the tribological properties [15][16][17][18][19][20][21], solid lubrication film and coating [22][23][24][25][26][27] and lubricant additive [28][29][30]. There is little information available about the discussion of friction and wear behavior of monolithic polymer nanocomposites reinforced by graphene [31,32].…”

“…Kim and Park [273] also studied the Q-factors of multilayer graphene NEMS, including both intrinsic effects (friction between the graphene monolayers), and extrinsic effects, or the effects of clamping strength between the graphene NEMS and the substrate. Interestingly, it was found that the quality of the attachment between the graphene NEMS and substrate had a strong effect on the Q-factor, where weaker attachment forces between the graphene NEMS and the substrate led to lower Q-factors.…”

Recent advances in nanotechnology have led to the development of nano-electro-mechanical systems (NEMS) such as nanomechanical resonators, which have recently received significant attention from the scientific community. This has not only been for their capability for the label-free detection of bio/chemical-molecules at single-molecule (or atomic) resolution for future applications such as the early diagnostics of diseases such as cancer, but also for their unprecedented ability to detect physical quantities such as molecular weight, elastic stiffness, surface stress, and surface elastic stiffness for adsorbed molecules on the surface. Most experimental works on resonator-based molecular detection have been based on the principle that molecular adsorption onto a resonator surface increases the effective mass, and consequently decreases the resonant frequencies of the nanomechanical resonator. However, this principle is insufficient to provide fundamental insights into resonator-based molecular detection at the nanoscale; this is due to recently proposed novel nanoscale detection principles including various effects such as surface effects, nonlinear oscillations, coupled resonance, and stiffness effects. Furthermore, these effects have only recently been incorporated into existing physical models for resonators, and therefore the universal physical principles governing nanoresonator-based detection have not been completely described. Therefore, our objective in this review is to overview the current attempts to understand the underlying mechanisms in nanoresonator-based detection using physical models coupled to computational simulations and/or experiments. Specifically, we will focus on issues of special relevance to the dynamic behavior of nanoresonators and their applications in biological/chemical detection: the resonance behavior of micro/nano-resonators; resonator-based chemical/biological detection; physical models of various nanoresonators such as nanowires, carbon nanotubes, and graphene. We pay particular attention to experimental and computational approaches that have been useful in elucidating the mechanisms underlying the dynamic behavior of resonators across multiple and disparate spatial/length scales, and the resulting insight into resonator-based detection that has been obtained. We additionally provide extensive discussion regarding potentially fruitful future research directions coupling experiments and simulations in order to develop a fundamental understanding of the basic physical principles that govern NEMS and NEMS-based sensing and detection applications.

“…9,28,29 As stated earlier, the performance of nanoresonators for sensing and transportation applications strongly depends on their dynamic characteristics such as quality (Q)-factor. [37][38][39] The Q-factor reflects the energy dissipated for each vibrational cycle of the resonators, which can be affected by the external attachment energy loss, 40,41 intrinsic nonlinear scattering mechanisms, 42 the effective strain mechanism, 43 edge effects, 44,45 grain-boundary-mediated scattering losses, 46 and temperature scaling phenomenon. 47 Moreover, the structure of nanoresonators has a large surface-to-volume ratio, which causes a difference in the nature of chemical bonds on the surface.…”

Nanotechnology has opened a new area in science and engineering, leading to the development of novel nano-electromechanical systems such as nanoresonators with ultra-high resonant frequencies. The ultra-high-frequency resonators facilitate wide-ranging applications such as ultra-high sensitive sensing, molecular transportation, molecular separation, high-frequency signal processing, and biological imaging. This paper reviews recent studies on dynamic characteristics of nanoresonators. A variety of theoretical approaches, i.e., continuum modeling, molecular simulations, and multiscale methods, in modeling of nanoresonators are reviewed. The potential application of nanoresonators in design of sensor devices and molecular transportation systems is introduced. The essence of nanoresonator sensors for detection of atoms and molecules with vibration and wave propagation analyses is outlined. The sensitivity of the resonator sensors and their feasibility in detecting different atoms and molecules are particularly discussed. Furthermore, the applicability of molecular transportation using the propagation of mechanical waves in nanoresonators is presented. An extended application of the transportation methods for building nanofiltering systems with ultra-high selectivity is surveyed. The article aims to provide an up-to-date review on the mechanical properties and applications of nanoresonators, and inspire additional potential of the resonators.
