摘要： The invention provides devices, systems, and methods for extracting target objects from a sample. In the method, a stream of sample containing a plurality of target and non-target objects is directed by first and second streams of buffer through a sample inlet channel into a fluid junction and through the fluid junction into a sample waste channel. In response to detecting a target object within the stream of sample, an actuator is energized to close a normally open valve, resulting in a transient burst of cross-flow into the fluid junction that briefly diverts the flow of sample within the fluid junction and results in an aliquot of sample being directed into an aliquot delivery channel. The combination of the valve and the actuator acts as a self-limiting pulse generator.

IPC分类号： B01L3/00
摘要： The invention provides microfluidic devices, systems, and methods for manipulating an object within a channel of a microfluidic device using an external electrode. The device has a channel disposed within the device, the channel having no included electrodes. The channel has a wall, at least a portion of which is penetrable by an electric field generated external to the device, the wall being penetrable such that the electric field extends through the wall portion and into a region within the channel. The system includes the microfluidic device and an electrode external to and not bonded to the device. In the method, the external electrode is placed adjacent to the device and energized to generate an electric field that extends through the wall of the device and into the channel, thereby manipulating an object within the channel.
