Bacteria separation from blood using microfluidic DLD device

Device used to separate bacteria from blood using the deterministic lateral displacement (DLD) technique.
DLD is a mechanical sorting technique relying on the streamlines of a laminar flow between an array of posts.  Smaller particles will zig-zag between the posts, while larger particles get 'bumped' to the edge of the device.

Here this is used to separate bacteria from blood to provide a purer sample of bacterial RNA for rapid identification.
