Abstract
This disclosure is directed to a device and a system for picking a target analyte of a suspension. A picker introduces at least one force, such as by a magnetic gradient and/or by a pressure gradient, to extract the target analyte from a specimen. The magnetic gradient may be introduced by a magnet, such as a permanent magnet or an electromagnet, and the pressure gradient may be introduced by a pump which moves within a fluid-primed cannula to create the pressure gradient, thereby drawing the target analyte into the cannula. The picker may also expel the target analyte onto or into a substrate, such as a well plate, after the target analyte has been drawn into the picker by reversing the pressure gradient or removing the magnetic gradient.
