Claim:
1. A microfluidic device for performance of chemical, biochemical or cellular assays, comprising an array of reaction units: wherein, each reaction unit comprises a test chamber where a chemical, biochemical or cellular assay is performed, wherein, each reaction unit further comprises of an external inlet that is specific to that reaction unit and is operably connected to the test chamber, wherein, each reaction unit further comprises a central channel that is operably connected to the test chamber, wherein, each reaction unit further comprises at least one top fluidic channel, or at least one bottom fluidic channel, or at least one top and bottom fluidic channel, that are each operably connected to the test chamber, wherein fluid can flow through a top or bottom channel without passing through the test chamber, wherein, each reaction unit contains control elements that can dynamically control the flow of fluid and particles between the test chamber and the external inlet, the test chamber and the central channel, the test chamber and the top channel, the test chamber and the bottom channel, and/or between the reaction unit and an adjoining reaction unit, wherein, a set of reaction units is operably connected to at least one inlet and at least one outlet corresponding to that set of reaction units, which are distinct from the external inlets specific to each reaction unit, wherein, a set of reaction units contains control elements that can dynamically control the flow of fluid and particles between reaction units within the set, wherein, the microfluidic device contains control elements that can control the flow of fluid and particles between the different reaction units.
