With the multi ton production of fullerene (C60) in industry due to its wide spread applications and commercialization, the concern of the biological and environmental effects of this compound has significantly increased.The ability to form stable aqueous C60 colloids (known as nano-C60 or nC60) and the availability of these in natural systems at environmentally-relevant concentrations led to the studies of its toxicity. In this research oxidation caused by fullerene colloidal suspensions is investigated by fluorescent assays to monitor oxidation with the probe molecule dihydrorhodamine-123 (DHR123). Presence of C60O in these colloidal suspensions considered to have increased ability of oxidation. To better understand the behavior of the probe molecule, calibration studies with common oxidants such as hydrogen peroxide (H2O2), ferric chloride (FeCl3) and potassium permanganate (KMnO4) were investigated. Method of initial rates was used to propose the rate equation for the oxidation observed.
