Modeling of the Halloysite Spiral Nanotube

The Journal of Physical Chemistry C, 2015
A computational SCC-DFTB investigation dealing with the structure of hydrated and anhydrous halloysite nanotubes with a spiral geometry is reported. The peculiar characteristics of these systems are described in terms of tetrahedral and octahedral distortions, of hydrogen bonds geometries involving water molecules and the surfaces in the hydrated ...

Halloysite Nanotube Coatings Suppress Leukocyte Spreading [PDF]

Langmuir, 2015
The nanoscale topography of adhesive surfaces is known to be an important factor governing cellular behavior. Previous work has shown that surface coatings composed of halloysite nanotubes enhance the adhesion, and therefore capture of, rare target cells such as circulating tumor cells.
