US Patent 7993541 - Quantum confined atom (QCA) nanomagnets


This patent from Nanocrystals Technology teaches a way to create luminescent quantum confined particles with magnetic materials that can assist in self-assembly of larger luminescent bio-tags and provide a means for moving luminescent nanoparticles with external magnetic fields. Claim 1 reads:

1. A particle of material comprising a plurality of magnetic host atoms in a nanoparticle of a size of 2-10 nm with a single atom of a magnetic dopant confined within and an anti-agglomeration coating surrounding the nanoparticle.
