| Abstract: A coaxial fluid flow microreactor system disposed on a microfluidic chip
utilizing laminar flow for synthesizing particles from solution. Flow
geometries produced by the mixing system make use of hydrodynamic
focusing to confine a core flow to a small axially-symmetric, centrally
positioned and spatially well-defined portion of a flow channel
cross-section to provide highly uniform diffusional mixing between a
reactant core and sheath flow streams. The microreactor is fabricated in
such a way that a substantially planar two-dimensional arrangement of
microfluidic channels will produce a three-dimensional core/sheath flow
geometry. The microreactor system can comprise one or more coaxial mixing
stages that can be arranged singly, in series, in parallel or nested
concentrically in parallel. |
