Gold nanocage

Gold Nanocages are hollow, porous gold nanoparticles ranging in size from 10 to over 150 nm.

They are created by reacting silver nanoparticles with chloroauric acid (HAuCl4) in boiling water.

Because they are also biocompatible, gold nanocages are promising as a contrast agent for optical coherence tomography.

Gold nanocages also absorb light and heat up (Photothermal effect), killing surrounding cancer cells.

Nanocages have been functionalized with cancer-specific antibodies.
