Surface acoustic waves are used to actuate and process smallest amounts of fluids on the
planar surface of a piezoelectric chip. Chemical modification of the chip surface is employed to
create virtual wells and tubes to confine the liquids. Lithographically modulated wetting
properties of the surface define a fluidic network, in analogy to the wiring of an electronic circuit.
Acoustic radiation pressure exerted by the surface wave leads to internal streaming in the fluid
and eventually to an actuation of small droplets along predetermined trajectories. This way, in
analogy to microelectronic circuitry, rogrammable biochips for a variety of assays on a chip
have been realized.
