Advanced Liquid Logic’s (ALL) digital microfluidics technology
is based on the electrowetting effect,
which manipulates droplets by applying voltages
to an array of independently controllable surface electrodes.
Individual droplets are dispensed,
transported,
merged,
or split according to user-defined automated programs.
All liquid operations are performed electrically
without need for pumps,
valves or channels.
Electrodes provided by a printed
circuit board drive droplet operations inside
the cartridge chamber
A droplet on a non-wetting surface is made to wet
the surface by application of an electrical potential
