More Information
Summary:A microfluidic device comprising a channel within a substrate and a condenser or a hydrodynamic focusing chamber along the channel, configured to focus a fluid containing particles of a plurality of sizes. A negative angle deterministic lateral displacement (DLD) array is configured to receive the focused fluid and separate the particles in the focused fluid into three sizes ranges. The negative angle DLD array comprises a plurality of rows of pillars, wherein the rows of pillars are positioned to repeat a pattern every N rows with a shift of M columns, N and M are relatively coprime, and N is greater than 1.
