Nanomaterial properties differ from those bulk materials of the same composition, allowing them to execute novel activities. A possible downside of these capabilities is harmful interactions with biological systems, with the potential to generate toxicity. An approach to assess the safety of nanomaterials is urgently required. We compared the cellular(More)
In this study we report on the electrokinetic behavior of colloidal aggregates of C60fullerenes (n-C60) produced through two different techniques: solvent exchange and extended mixing with water. In the first technique, used to produce colloidal materials in several recent toxicity and transport studies, an organic solvent such as tetrahydrofuran (THF) is(More)
