主权项

1. An enrichment platform device for size-based, label-free capture of particles in sample solution, the device comprising:
a substrate; vertically-aligned carbon nanotubes arrays (VACNT); and a cover having at least one inlet and at least one outlet; wherein the VACNT is attached to the substrate, the cover bonds to the substrate to seal the VACNT within the cover, and sample solution enters via the at least one inlet, passes over the VACNT, and exits via the at least one outlet, whereupon particles in the sample solution are captured by the gaps between the VACNT based on size.
