Abstract

Official abstract text for this publication.

The present invention discloses biocompatible, stable curcumin or its derivatives coated ultra-small super paramagnetic iron oxide nanoparticles (USPION) for biomedical applications. Disclosed herein is also a simple one-pot process for the synthesis of biocompatible, stable curcumin or its derivatives coated ultra-small superparamagnetic iron oxide nanoparticles in absence of a linker or binder. The curcumin or its derivatives coated ultra-small super paramagnetic iron oxide nanoparticles of the present invention retains the medicinal, radical scavenging and fluorescence properties of curcumin.

First claim

Opening claim text (preview).

We claim: 1. Curcumin coated magnetite nanoparticles comprising biocompatible, stable curcumin coated ultra-small super paramagnetic iron oxide nanoparticles devoid of any linker or binder, the curcumin coated magnetite nanoparticles having a particle size of about 3 nm, wherein the curcumin coated magnetite nanoparticle retains medicinal, radical scavenging and fluorescence properties of curcumin, for biomedical applications, wherein curcumin is directly coated on ultra-small super paramagnetic iron oxide nanoparticles. 2. A method for magnetic resonance or fluorescent imaging, the method comprising administering curcumin coated magnetite nanoparticles of claim 1 to a subject, and performing an imaging step. 3. A method for delivering curcumin to a subject in need thereof comprising administering curcumin coated magnetite nanoparticles, of claim 1 . 4. The curcumin coated magnetite nanoparticles of claim 1 , which are biocompatible, stable curcumin coated ultra-small iron oxide nanoparticles devoid of any linker or binder for use as a contrast agent for magnetic resonance fluorescent imaging. 5. The curcumin coated magnetite nanoparticles of claim 1 , which are biocompatible, stable, curcumin coated ultra-small iron oxide nanoparticles devoid of any linker or binder for use in delivering curcumin to a subject in need thereof.
