Anti-pathogen - Graphene Composites

GC HALO®

Dual action Nanotechnology - 'trap and kill' surface coatings

GC has developed a pioneering formulation, GC Halo® that destroys pathogens by forming a ‘trap and kill’ layer on air filters. Fast-acting, safe and more than 99% effective against SARS-CoV-2 coronavirus, flu, bacteria and mould. Independent tests and certifications prove GC Halo’s capabilities as a filter coating to deliver cleaner and safer indoor air.

GC Halo is a breakthrough technology, providing superior, long-lasting protection with broad applications where health, safety, and wellbeing are paramount.

Introduction to GC Halo

HOW GC HALO® WORKS

GC’s technology is highly eﬀective due to its dual action mechanism. The negatively-charged graphene oxide surface traps the positively-charged parts of water droplets and the protein spikes on coronavirus and other viruses. The silver nanoparticles oxidise the lipid membrane protecting coronavirus RNA, thereby killing it.

100% virucidal eﬃcacy on Human Coronavirus OC43 and Inﬂuenza A H1N1 viruses in liquid form, in less than one minute. Independently tested by Brown University
