This study reports the design, realization, and characterization of a multi-pole magnetic tweezers that enables us to maneuver small magnetic probes inside living cells. So far, magnetic tweezers can be divided into two categories: I), tweezers that allow the exertion of high forces but consist of only one or two poles and therefore are capable of only exerting forces in one direction; and II),...

Interactive manipulation of nanoparticles by mechanically pushing them with the tip of an AFM (Atomic Force Microscope) is now done routinely at many laboratories around the world. However, a human in the loop introduces significant inaccuracies and results in a very slow process, mostly because of the need for locating the particles before and after manipulation operations, in the presence of ...

In this paper, the fabrication process and electromechanical properties of novel atomic force microscopy probes utilising single-crystal boron-doped diamond are presented. The developed integrate scanning tips made chemical vapour deposition-grown, freestanding foil. procedure was performed using nanomanipulation techniques combined with electron focused ion beam technologies. mechanical cantil...

Plasmon decay via the surface or interface is a critical process for practical energy conversion and plasmonic catalysis. However, relationship between plasmon damping coupling 2D materials still unclear. The spectral splitting due to plasmon–exciton interaction impedes conventional single-particle method evaluate rate by linewidth. single gold nanorod using spectroscopy technique assisted with...

We report combined atomic force and far-field fluorescence microscopic experiments which allow the simultaneous atomic force manipulation and optical observation of individual dye-labeled DNA molecules. A detailed understanding of the binding properties of DNA to different transparent surfaces is prerequisite for these investigations. Atomic force spectroscopy and fluorescence microscopy of sin...

Nanowires of the wide band-gap semiconductor gallium nitride (GaN) have been shown to act as room-temperature uv lasers. Recent advances in nanomanipulation have made it possible to modify the shape of these structures from a linear to a pseudoring conformation. Changes to the optical boundary conditions of the lasing cavity affect the structure's photoluminescence, photon confinement, and lasi...

This report contains the findings of the first NSF workshop on the newly emerging area of nano-scale systems, dynamics and control. This workshop brought together many leading researchers from various disciplines and background for discussing the current status, future research directions, and potential applications of this new field. After giving a general background on nano-scale dynamics and...

In France, during the last decade, significant research activities have been performed in the field of micro and nano robotics. Generally speaking the microrobotic field deals with the design, the fabrication and the control of microrobots and microrobotic cells. These microrobots are intended to perform various tasks in the so-called Microworld. The scale effects from macroworld to microworld ...
