MULTI-COMPONENT NANOPARTICLE STRUCTURE HAVING DETECTABLE MAGNETIC RESONANCE PROPERTIES

摘要

A nanoparticle structure includes a sequence of segments. In particular, the structure includes a first plurality of segments comprising gold-coated DNA, and a second plurality of segments comprising DNA coated with a paramagnetic material. The first plurality of segments are interleaved with the second plurality of segments. The mass ratio of the combined mass of gold and paramagnetic material to a mass of DNA material is less than 5: 1.
