Tunneling Nanotubes
Tunneling nanotubes are actin-based cytoplasmic extensions that function as intercellular channels in a wide variety of cell types.There is a renewed and keen interest in the examination of modes of intercellular communication in cells of all types, especially in the field of cancer biology. Tunneling nanotubes -which in the literature have also been referred to as "membrane nanotubes," "'inter...
متن کاملTunneling nanotubes
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 enriched our knowledge on the diversity of TNT...

متن کاملNonequilibrium tunneling spectroscopy in carbon nanotubes.
We report measurements of the nonequilibrium 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. At low temperatures, electrons interact weakly in nanotubes of a few microns ch...
متن کاملTunneling spectroscopy on carbon nanotubes using STM
Single-wall carbon nanotubes (SWNTs) prepared on the graphite substrate were investigated by a low-temperature scanning tunneling microscope at 77K. From the tunneling spectra with high-energy resolution obtained at 77K, both metallic and semiconducting SWNTs were found in the same bundle. For the metallic SWNT, the conductance curve inside the first peak is finite and quite flat. The width bet...
