Oxygen reduction mediated by single nanodroplets containing attomoles of vitamin B12: Electrocatalytic nano-impacts method

We report the use of single Vitamin B<sub>12</sub> nanodroplets to mediate the reduction of oxygen in neutral buffer. Electron transfer to single Vitamin B<sub>12</sub> nanodroplets is observed using the nano-impacts method and shown to be quantitative. The mechanism of media...
