Killing bugs with gold and laser beams
Scientists have been able to kill an infectious parasite using non-toxic gold nanoparticles and laser beams.
“Our first target is Toxoplamosis gondii, a parasite that infects one in three people and causes problems especially in the young and old, and people with a compromised immune system says Michael Cortie from the University of Technology Sydney, speaking on behalf of his team at ICONN 2010 the international nanotechnology conference in Sydney.
