===Acoustic droplet ejection (ADE)===

[[Acoustic droplet ejection]] uses a pulse of [[ultrasound]] to move low volumes of [[fluids]] (typically nanoliters or picoliters) without any physical contact. This technology focuses acoustic energy into a fluid sample to eject droplets as small as a millionth of a millionth of a litre (picoliter = 10<sup>−12</sup> litre). ADE technology is a very gentle process, and it can be used to transfer proteins, high molecular weight DNA and live cells without damage or loss of viability. This feature makes the technology suitable for a wide variety of applications including [[proteomics]] and cell-based assays.
