Communicative & Integrative Biology, 2014 Tunneling nanotubes (TNTs) are recently discovered thin membranous tubes that interconnect cells. During the last decade, research has shown TNTs to be diverse in morphology and composition, varying between and within cell systems. In addition, the discovery of TNT-like extracellular protrusions, as well as observations of TNTs in vivo, has further ...

Tunneling Spectroscopy for Electronic Bands in Multi-Walled Carbon Nanotubes with Van Der Waals Gap
Molecules, 2021 Various intriguing quantum transport measurements for carbon nanotubes (CNTs) based on their unique electronic band structures have been performed adopting a field-effect transistor (FET), where the contact resistance represents the interaction between ...

Communications Biology, 2021 Pantazopoulou et al. find that AGO2 resides in open-ended tunneling nanotubes and close-ended cytokinetic bridges. At the latter location, AGO2 colocalizes with cell division components and the authors show that AGO2 depletion impairs cell division ...

Trojan horses and tunneling nanotubes enable α-synuclein pathology to spread in Parkinson disease.
PLoS Biology, 2021 In Parkinson disease (PD), Lewy bodies (LBs) form in the gut or nose and spread into the midbrain. A study in this issue indicates that the spread is due to lysosomes "infected" with prion-like alpha-synuclein (α-syn) transmitting from cell to cell via ...

Nonequilibrium Tunneling Spectroscopy in Carbon Nanotubes [PDF]
Physical Review Letters, 2009 We report measurements of the non-equilibrium electron energy distribution in carbon nanotubes. Using tunneling spectroscopy via a superconducting probe, we study the shape of the local electron distribution functions, and hence energy relaxation rates, in nanotubes that have bias voltages applied between their ends.

Suppression of Tunneling into Multiwall Carbon Nanotubes [PDF]
Physical Review Letters, 2001 We have studied tunneling of electrons into multi-wall carbon nanotubes. Nanotube/electrode interfaces with low transparency as well as nanotube/nanotube junctions created with atomic force microscope manipulation have been used. The tunneling conductance goes to zero as the temperature and bias are reduced, and the functional form is consistent with a

Superconductivity in carbon nanotube ropes [PDF]
, 2002 We investigate the conditions in which superconductivity may develop in ropes of carbon nanotubes. It is shown that the interaction among a large number of metallic nanotubes favors the appearance of a metallic phase in the ropes, intermediate between ...

Tunneling nanotubes: Reshaping connectivity
Current Opinion in Cell Biology, 2021 Tunneling nanotubes (TNTs), open membranous channels between connected cells, represent a novel direct way of communication between distant cells for the diffusion of various cellular material, including survival or death signals, genetic material, organelles, and pathogens.

Cell to cell hijacking: Role of membrane nanotubes
Asian Journal of Medical Sciences, 2022 Cell to Cell communications is the pivot for life processes. Any event that disrupts this leads to the loss of physiological function, eventually leading to cell death.
