Electrochemical Detection of Surfactant-Encapsulated Aqueous Nanodroplets in Organic Solution

We report enhanced electrochemical detection of single water-in-oil emulsion droplets using the nano-impact method. To detect droplets, water molecules in were directly oxidized (i.e., splitting) without additional electroactive species when collided with ultramicroelectrode. The droplet cannot be electrolyzed an organic solvent because emulsifier does not require a hydrophobic electrolyte. enhance signal intensity, electrochemistry sub-microscale was investigated considering charge neutrality and limiting reagent. Therefore, effective electrolysis achieved. Approximately 10% (55.6 M H2O) based on calculations from peak analysis DLS measurements.
