ABSTRACT:
Devices and methods are provided for reducing the uncontrolled electrostatic charges that can alter the volume and/or trajectory of a droplet, which is typically ejected through the application of focused acoustic radiation. Also provided are reservoirs and substrates, e.g., well plates formed from a material that is at least partially nonmetallic or polymeric and either has an electrical resistivity of no more than about 1011ohm-cm, has a surface electrical resistivity of no more than about 1012ohm/sq, or both.
