A breath of fresh air: The rate of aerial oxidation of dihydroethidium and hydrocyanine radical oxidant probes can be selectively reduced by deuteration (see picture). The reaction rate between the deuterated compounds and the superoxide radical was reduced by a much smaller factor because of mechanistic differences between the two reactions. The deuterated probes are more effective than their hydrogen
