Claim Text:
1. A sample assembly comprising: a substrate; one or more base layers formed on the substrate; an outer layer formed on the substrate; a plurality of sample trenches formed in the outer layer, each sample trench being characterized by an upper surface, a bottom surface, and a longitudinal axis; a first set of antibodies bonded to the sample assembly via the bottom surface of one or more of the sample trenches; and an electrical conductor disposed in the substrate, the electrical conductor being configured to generate an electromagnetic field in proximity to the plurality of sample trenches to enhance nanoparticle movement toward the bottom surface of the plurality of sample trenches; and at least one alignment trench formed in the outer layer, the alignment trench having a longitudinal axis substantially parallel to the longitudinal axis of at least one of the sample trenches, each alignment trench comprising non-magnetic markings configured to facilitate alignment of an electromagnetic write head of a magnetic tape drive.
