    摘要: Apparatus and methods for detecting, characterizing, and compensating motion-related error of moving micro-entities are described. Motion-related error may occur in streams of moving micro-entities, and may represent a deviation in and expected arrival time or an uncertainty in position of a micro-entity within the stream. Motion-related error of micro-entities is observed in a flow cytometer, e.g., as pulse jitter, and is found to have a functional dependence on a parameter of the system. The pulse jitter can be compensated, according to one embodiment, by adjusting data acquisition observation windows. For the flow cytometer, a reduction of pulse jitter can improve measurement accuracy, resolution of doublets, system throughput, and enable an increase in an interrogation region for probing the micro-entities.

    摘要: A hybrid microfluidic biochip designed to perform multiplexed detection of singled- celled pathogens using a combination of SPR and epi-fluorescence imaging. The device comprises an array of gold spots, each functionalized with a capture biomolecule targeting a specific pathogen. This biosensor array is enclosed by a polydimethylsiloxane (PDMS) microfluidic flow chamber that delivers a magnetically concentrated sample to be tested. The sample is imaged by surface plasmon resonance on the bottom of the biochip, and epi- fluorescence on the top.
