Coating nanoparticles

Creative Diagnostics offers novel gold coated magnetic nanoparticles, containing unique properties of both magnetic and AuNPs’ surface plasmon resonance. Magnetic nanoparticles, magnetite (Fe3O4) and maghemite (gFe2O3), have been the focus of research over the last decade due to their expansive applications in the field of targeted drug delivery, magnetic resonance imaging (MRI), cell labelling and separation, and hyperthermia treatment of cancer.

Presentation Transcript

  1. Coating nanoparticles

  2. Applications: • Magnetic separation • Biosensing • Magnetic hyperthermia • Drug delivery

  3. Various coating strategies have been employed to protect magnetic nanoparticles from oxidation and aggregation by using polymers and noble metals like gold, silica. Out of them, gold coating offers advantage of being chemically stable and biocompatible. It also provides the possibility of conjugating targeting ligands, drugs using gold-thiol chemistry, and for photothermal destruction of cancer cells. In gold coated magnetic nanoparticles, superparamagnetic nature of magnetic nanoparticles is retained with either a decrease or an increase in the value of saturation magnetization.
