Gold nanoparticles take out brain parasite

Abstract:
A novel technique to kill parasites in the human body uses a combination of gold nanoparticles and lasers, and has been shown to work on Toxoplasmosis gondii - a common parasite that causes cysts in the brain.

Current treatments for parasites often have unwanted side affects on other cells in the body. This new technique is target-specific, opening up exciting new possibilities for the treatment of pathogenic parasites and possibly other infectious agents as well.

"No-one's succeeded in using this technology on parasites before" said Michael Cortie, a nanoscientist from the University of Technology Sydney (UTS). "This is great because we can localise disease treatment".
