Abstract
A particle can be discretely ejected from a orifice.
Claims36
A method of delivering a particle comprising:
- providing a liquid including a particle to an exit orifice;
- sensing a condition at a meniscus of the liquid at the orifice;
- ejecting only a single particle through the meniscus by applying an electromagnetic signal to the liquid near the orifice for timed particle ejection based on the sensed condition to deliver the particle from the orifice after applying the electromagnetic signal.
A device for delivering a particle comprising:
- an orifice;
- a liquid including a particle to an exit orifice;
- a sensor capable of sensing particle condition at a meniscus of the liquid at the an exit orifice;
- and
- an electromagnetic supply configured to generate an electromagnetic field near the orifice to the liquid to eject only a single particle through the meniscus based on the sensor.

A device of delivering a particle comprising:
- a liquid containing one or more particles;
- an orifice through which a single particle is ejected from the liquid through the meniscus;
- and an electromagnetic supply configured to generate an electromagnetic field near the orifice to the liquid to eject only the single particle.
