ZENTEK GRANTED SECOND PATENT FROM THE CANADIAN INTELLECTUAL PATENT OFFICE

Zentek Ltd. has received a second patent by the Canadian Intellectual Property Office titled: Graphene Oxide-Cationic Silver (GO-Ag+) Nanocomposites and Their Use as a Broad-Spectrum Antimicrobial Agent and includes a total of 64 successful claims. The company also applied for this patent with the United States Patent and Trademark Office. The patent claims the novel GO-Ag+ compound, which is the active ingredient for Zenguard, as an effective agent against both regular and resistant bacteria, fungi and viruses. The patent claims liquid, powder and ointments that use GO-Ag+ as the active ingredient.

Zentek continues to do extensive work with GO-Ag+ in collaboration with the University of Guelph. In previous research, GO-Ag+ demonstrated substantially higher cytotoxicity against gram positive and negative bacteria than for human epithelial cells. In current research, the efficacy of GO-Ag+ is being studied to prevent and eliminate biofilms which is a critical challenge for wound care and various medical devices. These results, along with the new patent support future work to develop GO-Ag+ based products for medical and veterinarian markets including wound care products.

"We are very pleased to expand the use case and patent protection of the GO-Ag+ active ingredient in Zenguard and we see this as another important milestone in our IP commercialization strategy," said Greg Fenton, chief executive officer of Zentek. "Now that we have secured a patent for our GO-Ag+ formulation as a therapeutic that could apply to both human and veterinary medicine, we will focus on how to maximize shareholder value from this opportunity while balancing the other priorities of the company."
