Claim:
1. A method for transporting one or more droplets of one or more fluids from one or more reservoirs to contact one or more targets, the method comprising: generating acoustic radiation with an acoustic power level; ejecting a fluid droplet from a first fluid within a reservoir by the generated acoustic radiation; transporting the ejected fluid droplet at a droplet velocity towards a target; applying a predetermined electric field to the fluid droplet and the target, wherein applying the predetermined electric field comprises applying a voltage across first and second electrodes, the first electrode comprising a grid disposed behind the target; generating a dipole within the fluid droplet by the applied predetermined electric field; and attracting the fluid droplet to contact the target by an interaction between the dipole and the target; wherein the applying a predetermined electric field to the fluid droplet and the target is performed without substantially affecting the droplet velocity; wherein the attracting the fluid droplet to contact the target includes increasing, by the applied predetermined electric field, a likelihood that the fluid droplet does not splash or bounce on contacting the target.
