1. An apparatus, comprising:
a nanoscale deterministic lateral displacement array comprising alternating rows of inward displacement pillars and outward displacement pillars, wherein the alternating rows are connected and formed between and in fluid communication with an inlet bus and an outlet bus, and wherein the alternating rows form a Greek spiral or a serpentine configuration;
a global inlet in fluid communication with the inlet bus; and
a global outlet the outlet bus.
