1. A microfluidic device, comprising:

  • an enrichment module configured to receive a microdroplet of particle-containing fluid, the enrichment module comprising a flow-through member and an enrichment chamber, wherein the flow-through member is configured to allow fluid of the particle-containing fluid to pass through the flow-through member thereby accumulating an enriched particle sample, comprising particles of the particle-containing fluid, in the enrichment chamber;

    a downstream channel leading downstream from the enrichment chamber to at least one downstream processing module;

    an actuator configured to move the enriched particle sample downstream from the enrichment module along the downstream channel; and

    a first valve disposed between the actuator and the flow-through member.
