SALT LAKE CITY, UT, Sept. 09, 2019 (GLOBE NEWSWIRE) -- SINTX Technologies, Inc. (NASDAQ: SINT) (the “Company”), an OEM ceramics company that develops and commercializes silicon nitride for medical and non-medical applications, today provided an update on its patent portfolio.

The Company announced the provisional filing of a new patent titled “Methods of Surface Functionalization of Zirconia-Toughened Alumina with Silicon Nitride.” “This innovation expands the scope of our technology yet further, by enabling the surface transformation of zirconia-toughened alumina (ZTA), a material widely used in hip replacements worldwide,” said Dr. Sonny Bal, Chairman of SINTX Technologies. “ZTA has proven durability as a weight-bearing implant for decades, but its surface chemistry precludes bone healing. By 3-D laser-patterning silicon nitride into microscopic surface wells on ZTA, we combined the best properties of two different ceramics into one composite structure. A parallel project is targeting similar surface treatment of orthopaedic titanium alloy as well, in order to add the osteointegrative and antibacterial properties of silicon nitride to that widely-used material. These technologies, detailed in forthcoming publications, will expand the range of opportunities for SINTX,” added Dr. Bal.

SINTX updated the status of its 2018 provisional patent filing on the anti-viral properties of silicon nitride. The provisional filing has been transitioned to Non-provisional and PCT International Applications. The patent application relates to breakthrough research findings that identified a new property of proprietary silicon nitride. SINTX investigators led by Dr. Giuseppe Pezzotti, a professor at the Kyoto Institute of Technology (Japan) and consultant to SINTX, developed micromeritic silicon nitride powders as well as bulk surfaces that have shown in in vitro studies to be effective against several strains of commonly prevalent viruses - including Influenza A virus (H1N1), the virus responsible for the 2009 flu pandemic. As one application, thin, transparent coatings of silicon nitride have been applied to glass, toward developing antimicrobial solutions for the touchscreen glass industry. Several publications over the past 12 months attest to the scientific foundations of this work.
