1. A microfluidic device, comprising:

  • a microfluidic network, wherein the microfluidic network comprises several modules, including;

    an enrichment module configured to accept a particle-containing fluid sample, and to create an enriched sample therefrom;

    a microdroplet preparation module configured to receive the enriched sample and to create a microdroplet therefrom;

    a cell lysing module configured to lyse the microdroplet of enriched sample;

    a mixing module configured to mix one or more reagents and the enriched sample; and

    a DNA manipulation module configured to receive the enriched sample mixed with one or more reagents;

    wherein the several modules are operatively connected to one another by one or more channels; and

    wherein at least one of the several modules is isolatable by a valve; and

    wherein at least one actuator is configured to move a microdroplet of fluid from one of the several modules to another of the several modules.
