10:14 AM EDT, 05/27/2024 (MT Newswires) -- Zentek ( ZTEK ) was at last look up 2.7% on Monday after saying it has received a second patent by the Canadian Intellectual Property Office that includes 64 successful claims.

A statement noted the patent claims the graphene oxide-cationic silver (GO-Ag+) compound (the active ingredient for ZenGUARD) is 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 ( ZTEK ) said it is doing "extensive work" with GO-Ag+ in collaboration with the University of Guelph. In previous research, the compound 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 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.
