1. A microfluidic system for converting a serial flow of materials into a parallel flow of materials, the system comprising:
- a body structure;
a first chamber disposed within the body structure, the chamber having at least two sets of opposing sides;
a first sample introduction channel for transmitting the serial flow of materials, in fluid communication with the chamber on a first side;
a first plurality of parallel channels in fluid communication with the chamber on a second side that is not opposite to the first side;
a second plurality of parallel channels for receiving the parallel flow of materials, in fluid communication with the chamber on a third side, the third side being opposite the second side;
a controller operably coupled to the first sample introduction channel and to at least one of the first and second plurality of parallel channels, wherein the controller is configured to transport the serial flow of materials into the chamber from the first sample introduction channel and to transport the serial flow of materials out of the chamber through the second plurality of parallel channels, whereby the serial flow of materials is transported into the second plurality of parallel channels in a parallel orientation; and
, a detector system operably coupled to one or more channels, wherein the detector system is configured to detect one or more signals from the one or more channels.

Abstract
Microfluidic devices and systems for affecting the serial to parallel conversion of materials introduced into the device or system. Material or materials to be converted from a serial orientation, e.g., a single channel, into a parallel orientation, e.g., multiple channels, are introduced into an open chamber or field in which containing flows of materials maintain the cohesiveness of the sample material plugs serially introduced into the open chamber. The sample material or materials are then redirected in the chamber toward and into a plurality of parallel channels that also communicate with the chamber.
