Reciprocal redox interactions of lithium cobalt oxide nanoparticles with nicotinamide adenine dinucleotide (NADH) and glutathione (GSH): toward a mechanistic understanding of nanoparticle-biological interactions

NADH and GSH reduce Co in LiCoO2 nanoparticles to enhance ion release and the nanoparticles oxidize NADH in model media. This poses two routes of toxicity for high-valent oxides: enhanced release of toxic metals and disruption of cell redox state.
