Graphene oxide: a nonspecific enhancer of cellular growth.
Oscar N. Ruiz,K. A. Shiral Fernando,Baojiang Wang,Nicholas A. Brown,Pengju G. Luo,Nicholas D. McNamara,Marlin D. Vangsness,Ya-Ping Sun,Christopher E. Bunker +8 more
TL;DR: This study conclusively demonstrates that graphene oxide does not have intrinsic antibacterial, bacteriostatic, and cytotoxic properties in both bacteria and mammalian cells, and graphene oxide acts as a general enhancer of cellular growth by increasing cell attachment and proliferation.

Lateral Dimension-Dependent Antibacterial Activity of Graphene Oxide Sheets
Shaobin Liu,Ming Hu,Tingying Helen Zeng,Ran Wu,Rongrong Jiang,Jun Wei,Liang Wang,Jing Kong,Yuan Chen +8 more
TL;DR: In this study, GO sheets with different lateral sizes are all well dispersed, and their oxidation capacity toward glutathione is similar, consistent with X-ray photoelectron spectroscopy and ultraviolet-visible absorption spectroscopic results, which suggests the lateral size-dependent antibacterial activity of GO sheets is caused by neither their aggregation states, nor oxidation capacity.

The rise of graphene
TL;DR: Owing to its unusual electronic spectrum, graphene has led to the emergence of a new paradigm of 'relativistic' condensed-matter physics, where quantum relativistic phenomena can now be mimicked and tested in table-top experiments.

Chemically Derived, Ultrasmooth Graphene Nanoribbon Semiconductors
TL;DR: A chemical route to produce graphene nanoribbons with width below 10 nanometers was developed, as well as single ribbons with varying widths along their lengths or containing lattice-defined graphene junctions for potential molecular electronics.

Electronic Confinement and Coherence in Patterned Epitaxial Graphene
TL;DR: The transport properties, which are closely related to those of carbon nanotubes, are dominated by the single epitaxial graphene layer at the silicon carbide interface and reveal the Dirac nature of the charge carriers.
