RNA transfer through tunneling nanotubes

Biochemical Society Transactions, 2020
It was already suggested in the early ‘70's that RNA molecules might transfer between mammalian cells in culture. Yet, more direct evidence for RNA transfer in animal and plant cells was only provided decades later, as this field became established. In this mini-review, we will describe evidence for the transfer of different types of RNA between cells ...

Interpericyte tunnelling nanotubes regulate neurovascular coupling

Nature, 2020
Signalling 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

Tunneling nanotube radio

Journal of Applied Physics, 2008
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 ...

Intercellular transfer mediated by tunneling nanotubes

Current Opinion in Cell Biology, 2008
Animal 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.

Electron tunneling in carbon nanotube composites

Nanotechnology, 2009
Nanocomposites, 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.

Tunneling conductance of connected carbon nanotubes

Physical Review B, 1996
A 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.

Scanning tunnelling microscopy of carbon nanotubes

Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2004
This 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.
