SINTX Technologies Announces Publication of Study to Reduce the Spread and Transfer of Coronavirus

SINTX Technologies, Inc. (NASDAQ: SINT) (“SINTX” or the “Company”), an original equipment manufacturer (OEM) ceramics company focused on silicon nitride and its applications, today announced positive testing results demonstrating the anti-viral properties of its silicon nitride which may be useful in the reduction of the spread of COVID-19. The study results demonstrated that SINTX’s unique grade of silicon nitride inactivates the SARS-CoV-2 virus within a minute after exposure, and has the potential to decrease the risk of viral disease spread on surfaces.

Studies have shown that coronavirus spreads between humans when an infected person coughs or sneezes. Also, the virus can remain active on a variety of commonly touched surfaces for hours to days. SINTX believes that by incorporating its unique composition of silicon nitride into products such as face masks, and personal protective equipment, it is possible to manufacture surfaces that inactivate viral particles, thereby limiting the spread of the disease. SINTX envisions incorporating its silicon nitride into high-contact surfaces such as medical equipment, screens, countertops, and doorknobs in locations where viral persistence is a concern, such as homes, casinos, and cruise ships.

“The study builds upon years of research toward understanding the basic biochemistry of silicon nitride,” said Dr. Sonny Bal, President, and CEO of SINTX. “The antiviral attributes of silicon nitride are consistent with the known antibacterial behavior of silicon nitride. The results with coronavirus inactivation are likewise consistent with an earlier study that showed similar inactivation of other viruses, including Influenza A and Enterovirus, both of which cause human disease.”

“The study and testing results show promise toward developing a new category of face masks for healthcare professionals and general consumers,” said Bruce Lorange, Founder, and CEO, O2TODAY. “Face masks used by healthcare workers today can capture virus particles, but the virus can remain viable in the mask, even as long 7 days after use. Inclusion of silicon nitride technology into the mask may enhance personal safety while reducing the risk of disease spread.”

“This antiviral discovery opens many new opportunities for SINTX. In composites, coatings, and mixtures, silicon nitride has maintained its antibacterial and osteogenic properties, even at small fractions. We believe that incorporating our material into a variety of commonly-touched surfaces will discourage viral spread, and contribute to global health by reducing the risk of disease,” Dr. Bal added.

The present study was done independently, with SINTX supplying its silicon nitride for the testing. The complete data and study can be downloaded at bioRxiv. Additional tests are underway at several U.S. research centers to further understand the isolation and optimization of the antiviral properties of silicon nitride; those results will be shared as they become available.
