Claim:
1. A centrifugal microfluidic device comprising a microfluidic mixing chamber with at least two inlets from respective microfluidic channels with hydraulic diameters less than 1 mm, for permitting fluid flows to enter the chamber from each channel under the influence of a centrifugal field, the inlets spaced apart so that trajectories of the fluid do not intersect a mixing surface in the chamber at substantially a same place on the surface, the chamber having at least one deflection element situated in the trajectories, the at least one deflection element oriented to deflect the flow so that the deflected flows contact the mixing surface at substantially a same place on the surface, where a trajectory from the deflection element to the mixing surface has a distance of at least 1 mm, so that microscopic amounts of the fluid flows impact the surface, or the previously deposited fluid, spreading out to form a stack of alternating thin layers of the respective fluids, providing a large surface area for diffusion.
