TL;DR: The enzymatic oxidation of a single layer of graphitic carbon by horseradish peroxidase (HRP) resulted in the formation of holes on its basal plane, which rendered hRGO, which can be conceptualized as interconnected graphene nanoribbons, as a potentially attractive material for FET sensors.

TL;DR: It was observed that pristine SWNTs demonstrate no degradation with HRP incubation but display significant degradation when incubated with either hemin or FeCl(3), which may signify a heterolytic cleavage of H(2)O( 2) withHRP as pristine nanotubes do not degrade, whereas Fenton catalysis results in the homolyticCleavage producing free radicals that oxidize pristineSWNTs.

TL;DR: This is the first demonstration of the in vivo adsorption of the surfactant lipids and proteins on SWCNTs in a physiologically relevant animal model and it is demonstrated that the presence of this Surfactant coating markedly enhanced the in vitro uptake of SWC NTs by macrophages.

TL;DR: This work reports the fabrication of nanosensors based on holey reduced graphene oxide (hRGO), which can be visualized as interconnected graphene nanoribbons and proposes that the increased edge-to-plane ratio, oxygen moieties, and Pt nanoparticle decoration were responsible for the observed gas sensing with hRGO nanostructures.

TL;DR: Human EPO (in vitro) and ex vivo activated eosinophils mediate biodegradation of SWCNTs: an observation that is relevant to pulmonary responses to these materials.
