Study Shows Silver Nanoparticles Attach to HIV-1 virus

In the first-ever study of metal nanoparticles'
interaction with HIV-1, silver nanoparticles of
sizes 1-10nm attached to HIV-1 and prevented the
virus from bonding to host cells. The study,
published in the Journal of Nanotechnology, was a
joint project between the University of Texas,
Austin and Mexico Univeristy, Nuevo Leon.
Scientists are also studying other uses for
silver nanoparticles. "We're testing against
other viruses and the 'super bug (Methicillin
resistant staphylococcus aureus).' Our
preliminary results indicate that silver
nanoparticles can effectively attack other micro-
organisms," Yacaman said.

ionic/colloidal silver. There have already been
many in vitro kill studies on other microbes.
