We theoretically investigate shuttle instability induced by an ac gate in a nanoelectromechanical singleelectron transistor containing a moveable grain. The ac gate causes periodic variations of charge on the grain, which turn ͑in the bias field͒ to driving force of grain vibrations. The forced grain vibrations and related electron transport show drastic and hysteretic changes for variations of the bias or the gate frequency due to transitions in transport mechanisms between tunneling and shuttling.

“…This combination of specific, programmable supramolecular structures with diverse functional units in a single, entirely RNA compound, allows precise positioning of different functional modules in three-dimensional space. This, for example, can provide an avenue to address the vital problems of stability, targeting, and multivalency in nanomedicine [95,102,103,107], and can form the basis of preprogrammed arrays [43], mediate the growth and distribution of other NPs [94,108], or form patterned scaffolds for tissue engineering or other applications [47].…”

IntroductionThe physical world presents a very different landscape at the nanometer scale. Physical phenomena such as inertia and gravity vanish from view; instead the interactions of matter and energy are dominated by other phenomena like wave-particle duality, uncertainty, and quantum electrodynamics. Nanotechnology is the engineering of functional systems at this scale, where the axioms that govern material and device design differ dramatically from those found at the macroscale level. More precisely, "nanotechnology" typically encompasses both the miniaturization of existing technologies to the nanoscale, and the discipline of engineering molecular-scale systems from the bottom up, producing constructs with fundamentally new qualities that revolutionize human engineering, from materials and manufacturing, electronics, and information technology, to medicine, biotechnology, energy, and even security. The array of goals and applications in nanotechnology intersects with an equally wide array of techniques and materials with their own emergent properties in the field. One such branch is concerned with the re-engineering of biological mechanisms, systems, and molecules in new forms with new utilities, broadly termed bio-nanotechnology.The field of nanotechnology taking advantage of nucleic acids has its origins in the work of Nadrian Seeman and coworkers who have, over the past 30 years, spearheaded the development of DNA nano-object fabrication utilizing DNA self-assembly [1][2][3][4][5][6]. Briefly, DNA nanotechnology uses the nature of DNA complementarity for the construction of DNA tiles with discrete secondary structure by canonical WatsonCrick interactions (G-C and A-T base pairing), using a relatively small number of structural rules fundamentally based on Holliday junction motifs. The use of these rules has resulted in the engineering and characterization of numerous DNA 3D nanoscaffolds with different connectiviities [7][8][9][10][11][12][13][14][15][16][17][18] and the ability for some of them to promote targeted delivery by functioning as DNA nano-capsules [19][20][21] or DNA nano-carriers for other functionialities [22]. Another powerful technique called DNA "origami", developed by Paul Rothemund [23], has been extended from its original scope for designing different 2D DNA shapes [24] and functional templates [25][26][27][28] Abstract Nucleic acids have emerged as an extremely promising platform for nanotechnological applications because of their unique biochemical properties and functions. RNA, in particular, is characterized by relatively high thermal stability, diverse structural flexibility, and its capacity to perform a variety of functions in nature. These properties make RNA a valuable platform for bio-nanotechnology, specifically RNA Nanotechnology, that can create de novo nanostructures with unique functionalities through the design, integration, and re-engineering of powerful mechanisms based on a variety of existing RNA structures and their fundamental biochemical properties.

We investigate theoretically the transport characteristics of a single electron transistor affected by the dynamic deformation of the device configuration due to phonons. By considering changes in capacitances and tunnel resistances caused by the breathing and oblong vibrations of the island that forms part of the transistor, we formulate the electron-phonon interaction peculiar to the device and derive its transport properties by means of the master equation. For a single electron transistor with a gold nano particle island of radius 1 nm, we demonstrate the contribution to the transport properties that originates from tunneling channels associated with THz phonon emission and absorption.
