Abstract

Devices and methods are provided for reducing uncontrolled electrostatic charge that can alter the volume and/or trajectory of a droplet, which may be 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 10<11> ohm-cm, has a surface electrical resistivity of no more than about 10<12> ohm/sq, or both.
