Claim 7:
8. A particle monitoring system comprising:
a flow passage;
a particle imager to image a targeted particle within the flow passage;
electrodes supported proximate the flow passage;
a power source connected to the electrodes;
a controller to cause the power source to charge the electrodes so as to (1) apply an electric field balanced with respect to gravity so as to hold, levitate and rotate a targeted particle within the flow passage during imaging and (2) release the targeted particle following the imaging;
an ejection orifice extending from the flow passage;
a fluid actuator to selectively eject fluid from the flow passage through the ejection orifice;
a multi well plate; and
an actuator coupled to at least one of the ejection orifice and the multi well plate to selectively position the ejection orifice and an individual well of the multi well plate relative to one another for depositing fluid ejected through the ejection orifice into the individual well.
