1. A method, comprising:
- providing a droplet having a first chemical species and a second different chemical species on a substrate, the first chemical species and the second chemical species having a concentration gradient with respect to each other;
applying a voltage across the droplet to physically repeatedly deform the droplet in a direction substantially perpendicular to the substrate, wherein the applying causes the droplet to move at least two full cycles between less flattened and more flattened states with respect to an object located therein and while the object is located therein and thereby at least partially mix the first chemical species with the second chemical species thereby changing the concentration gradient.

Abstract
A method comprising, providing a droplet having a first chemical species and a second chemical species on a substrate, and applying a voltage across the droplet to physically repeatedly deform the droplet. In this embodiment, the applying causes the droplet to move with respect to an object located therein and at least partially mix the first chemical species and the second chemical species.
