How GC Halo® Works

GC’s technology is highly effective due to its dual-action mechanism: the negatively-charged surface of graphene oxide traps the positively-charged parts of water droplets and the protein spikes on coronavirus and other viruses; the silver nanoparticles oxidize 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
  • At least 99% virucidal efficacy on textiles, independently tested in the UK according to ISO 18184:2019
  • GC Halo® coated air filters proven 99.99% efficacy against mould (Aspergillus brasiliensis)
  • Proven to destroy over 99.99% of Staphylococcus aureus and Escherichia coli
  • No observable ink particulates in airflow tests
  • Independently tested to have no measurable impact on airflow

Virucidal Air Filtration – A new paradigm in indoor air quality

A presentation by Dr Steve Devine, CTO of GC. The presentation was first given at the 2022 Medical AM conference in Birmingham, UK. The presentation gives an introduction to the new technology GC Halo® a virucidal solution for air filtration systems.


Graphene oxide/silver nanoparticle ink formulations rapidly inhibit influenza A virus and OC43 coronavirus infection in vitro

Meredith J. Crane, Senior Research Associate and Amanda M. Jamieson, Associate Professor, Department of Molecular Microbiology and Immunology at Brown University tested the in vitro antiviral properties of GC`s graphene oxide–silver nanoparticle composite materials for their antiviral activity against two enveloped RNA viruses, influenza A virus and OC43 coronavirus.

GC’s formulation was able to completely inhibit plaque formation by both viruses within one minute of exposure. These studies indicate that graphene oxide-silver nanoparticle composite materials can rapidly neutralize RNA viruses and demonstrate their potential for use in various applications
