University Study Shows Ionic Silver Effective Against SARS
Monday June 13, 9:56 am ET
Supports Previous Research Findings on SARS Virus


WAKEFIELD, Mass.--(BUSINESS WIRE)--June 13, 2005--AgION
Technologies, Inc., a leading provider of engineered antimicrobial
solutions, today announced that its research efforts have
demonstrated that ionic silver was found to effectively deactivate
the human coronavirus strain 229E, a virus linked to SARS, during a
laboratory study conducted by the University of Arizona.
The study, led by C.P. Gerba, Ph.D. and K.R. Bright, Ph.D., tested
various ionic silver and copper levels to determine if they were
effective against the human coronavirus strain 229E, a strain
commonly used as a surrogate for the SARS virus in laboratory
research. The research demonstrated significant reductions of the
virus within 1 hour (90 percent) and reduced virus levels to below
the detection limit following 24 hours of exposure (99.99 percent).

"These are very exciting results," said Dr. Gerba. "The fact that
the ionic silver is effective against this human coronavirus strain
suggests that it may also be effective in reducing the human SARS
virus, which has caused widespread illness in numerous countries
throughout the world. Since the compound is both safe and effective,
there are countless potential applications."

This study supports previous findings from research on the human
SARS virus and the feline coronavirus. A 2003 study by the Chinese
Center for Disease Control and Prevention found the ionic silver
completely deactivated the human SARS virus after 2 hours. In
addition, a laboratory study conducted by University of Arizona in
2003 found the ionic silver deactivated 99% of the feline
coronavirus within 4 hours.

"The research demonstrates that ionic silver has the potential to
deactivate viruses in a relatively short period of time," said Jeff
Trogolo, Ph.D., chief technology officer, AgION Technologies,
Inc. "Studies have shown that coronaviruses can survive on surfaces
for several hours - even days in some cases - so there is an
exciting potential for the AgION technology to be developed into
solutions which are used in the reduction of these viruses on
contaminated surfaces."

The AgION antimicrobial compound is comprised of naturally occurring
silver ions and a ceramic material called a zeolite. It is safe,
long lasting and has proven effective against a broad range of
microorganisms, including bacteria, algae, and fungus such as mold
and yeast. AgION antimicrobials are used in a wide variety of
applications and can be found in appliances, building products,
heating, ventilation, air conditioning, medical devices, water
filtration and delivery systems, food processing and packaging, and
numerous other consumer, industrial and medical products. AgION's
antimicrobial products are not currently registered with the
Environmental Protection Agency to claim efficacy against the
coronaviruses.
