Electrochemical Studies of Reactions in Small Volumes Less Than 1 Femto Litres.

<p>Electrochemical methods have been used to study electron transfer reactions at the interface between an aqueous phase of less than 1 femto liters in volume and a bulk organic phase. The small aqueous phase is formed at the end of a slightly recessed platinum electrode. When a negative potential is applied between the Pt electrode and the aqueous phase, Ru(NH₃)₆³⁺ in the aqueous phase could be reduced to Ru(NH₃)₆²⁺. Because the volume of the aqueous phase is very small, the electrochemically formed Ru(NH₃)₆²⁺ could instantly reach the interface between the aqueous phase and the organic phase which contains 7,7,8,8-Teteracyanoquinodimethane (TCNQ), and be oxidized to form Ru(NH₃)₆³⁺ by giving electrons to TCNQ at the interface. Our results showed a positive shift in the E_1/2 comparing the reaction undertaken in the recessed cavity and the bulk solution.</p>
