1. A microfluidic system comprising:
- a body structure comprising at least first, second and third substrate layers, the second substrate layer being disposed between the first and third substrate layers;
at least first and second microfluidic channels disposed in the second substrate layer, wherein the at least first and second channels intersect at an intersection;
at least a first port disposed through the first substrate layer, the at least first port being fluidly coupled to at least one of the first and second microfluidic channels;
a material transport system which is configured to controllably direct material flow through the intersection; and
a detector disposed in sensory communication with a detection region associated with at least the first microfluidic channel which detector is configured to detect a detectable signal emitted from the first microfluidic channel.

Abstract
The present invention provides multi-layer microfluidic systems, by providing additional substrate layers, e.g., third, fourth, fifth and more substrate layers, mated with the typically described first and second layers. Microfabricated elements, e.g., grooves, wells and the like, are manufactured into the surfaces between the various substrate layers. These microfabricated elements define the various microfluidic aspects or structures of the overall device, e.g., channels, chambers and the like. In preferred aspects, a separate microscale channel network is provided between each of the substrate layers.
