Gold nanoparticle conjugates and uses thereof

摘要

The disclosure generally relates to formation of polymers grafted to or polymerized from the surface of gold nanoparticles. The polymers are functionalized to include therapeutic agents and/or targeting agents at their surface, thereby allowing both therapeutic and targeting compounds to be directed to specific cells in a patient.
