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.

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.

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.

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.

Identification and Characterization of Tunneling Nanotubes for Intercellular Trafficking

Current Protocols in Cell Biology, 2015
AbstractTunneling 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, 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 Nanotubes: Implications for Chemoresistance

Tunneling nanotubes (TNTs) are thin, membranous protrusions that connect cells and allow for the transfer of various molecules, including proteins, organelles, and genetic material. TNTs have been implicated in a wide range of biological processes, including intercellular communication, drug resistance, and viral transmission. In cancer, they have been

Tunneling nanotube formation is essential for the regulation of osteoclastogenesis

Journal of Cellular Biochemistry, 2013
AbstractOsteoclasts are the multinucleated giant cells formed by cell fusion of mononuclear osteoclast precursors. Despite the finding of several membrane proteins involving DC‐STAMP as regulatory proteins required for fusion among osteoclast precursors, cellular and molecular events concerning this process are still ambiguous.
