Query: Sorting of particles suspended in whole blood   An important step in diagnostics is the isolation of specific cells and
microorganisms of interest from blood. Since such bioparticles are often
present at very low concentrations, throughput needs to be as high as possible.
In addition, to ensure simplicity, a minimum of sample preparation is
important. Therefore, sorting schemes that function for whole blood are highly
desirable. Deterministic lateral displacement (DLD) has proven to be very
precise and versatile in terms of a wide range of sorting parameters. To better
understand how DLD performs for blood as the hematocrit increases, we have
performed measurements and simulations for spherical particles in the
micrometer range moving through DLD arrays for different flow velocities and
hematocrits ranging from pure buffer to whole blood. We find that the
separation function of the DLD array is sustained, even though blood cells
introduce a shift in the trajectories and a significant dispersion for
particles that are close to the critical size in the device. Simulations
qualitatively replicate our experimental observations and help us identify
fundamental mechanisms for the effect of hematocrit on the performance of the
DLD device.
