separate microRNA from mixtures of nucleic acids tagged posts

(A) An image of the nanobiodevice (left), an SEM image of the hybrid structure of nanopillars and nanoslits (middle), and the magnified SEM image (right). (B) Schematic of the hybrid structure of nanopillars and nanoslits around the cross injector. (C) Diagram showing the scheme of sample injection. Figure panels C-a to C-e are arranged by time in ascending order. Sample of nucleic acids and direction of electrophoretic migration are depicted in green diagonal and blue arrows, respectively. Suggested dominant mechanisms for each process are shown at the bottom.
