Abstract
Official abstract text for this publication.
The invention provides core-shell magnetic particles comprising a magnetic core and a functional shell, methods for making same, methods of separation using same, methods for using same, and devices comprising same. The particles and methods of the invention are useful for targeting and removing substances of interest that may be found in complex mixtures.
First claim
Opening claim text (preview).
We claim: 1. A particle, comprising a plurality of magnetic nanoparticles, and a silicon oxide shell surrounding the plurality of magnetic nanoparticles, wherein the silicon oxide shell integrally comprises a plurality of functionalized alkyl silanes, wherein each functionalized alkyl silane comprises a reactive functional group which is an electrophilic group. 2. The particle of claim 1 , wherein the magnetic nanoparticles comprise magnetite.…
