The tunneling nanotube radio is a miniaturized radio based on a single nanotube. The tunneling nanotube radio is electrically tunable in the entire FM or AM band and is biased with batteries. These features of the tunneling nanotube radio are in contrast with previous nanoradio based on field emission, which is biased at a few hundred volts and not ...

Electron tunneling in carbon nanotube composites
Nanotechnology, 2009Nanocomposites, such as polymer blending with carbon nanotubes (CNTs), have been shown to have a drastic reduction in the resistivity and become conductive when the CNTs concentration has reached a certain percolation threshold. The reduction could be more than a millionth of the original polymer material.

Structure and elastic properties of tunneling nanotubes
European Biophysics Journal, 2007We investigate properties of a reported new mechanism for cell-cell interactions, tunneling nanotubes (TNT's). TNT's mediate actin-based transfer of vesicles and organelles and they allow signal transmission between cells. The effects of lateral pulling with polystyrene beads trapped by optical tweezers on TNT's linking separate U-87 MG human ...

Intercellular transfer mediated by tunneling nanotubes
Current Opinion in Cell Biology, 2008Animal cells have evolved different mechanisms to communicate with one another. In 2004, a new route of cell-to-cell communication mediated by tunneling nanotubes (TNT) was reported. These membranous cell bridges form de novo between cells and mediate the intercellular transfer of organelles, plasma membrane components and cytoplasmic molecules.

Scanning tunnelling microscopy of carbon nanotubes
Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2004This paper briefly reviews how scanning tunnelling microscopy (STM) and spectroscopy (STS) are used to analyse the atomic structure and the electronic properties of individual single-wall carbon nanotubes. In this area, the progress accomplished over the past several years has been spectacular.

Tunneling conductance of connected carbon nanotubes
Physical Review B, 1996A three-dimensional structure of two carbon nanotubes (CN) joined by a connecting region containing a pentagon and heptagon pair is given by the use of a projection method. The connecting joint is uniquely determined for the given two chiral vectors of CN by a vector which defines a three-dimensional dihedral angle.

Identification and Characterization of Tunneling Nanotubes for Intercellular Trafficking
Current Protocols in Cell Biology, 2015AbstractTunneling nanotubes (TNTs) are thin membranous channels providing direct cytoplasmic connection between remote cells. They are commonly observed in different cell cultures and increasing evidence supports their role in intercellular communication and pathogen transfer.

Interpericyte tunnelling nanotubes regulate neurovascular coupling
Nature, 2020Signalling between cells of the neurovascular unit, or neurovascular coupling, is essential to match local blood flow with neuronal activity. Pericytes interact with endothelial cells and extend processes that wrap capillaries, covering up to 90% of their surface area1,2. Pericytes are candidates to regulate microcirculatory blood flow because they are
