GC INK™

Dual action Nanotechnology - 'trap and kill' surface coatings

GC Ink™ is a new, powerful formulation that forms a virucidal and antimicrobial coating onto a surface. A formulation that works on a nano-scale, GC Ink has a dual action, ‘trap-and-kill’ nano-chemistry where two nanomaterials – graphene oxide and silver nanoparticles – work together.

GC Ink provides superior, long-lasting protection against viruses and bacteria with broad applications where health, safety, and wellbeing are paramount.

GC Ink can be:

  • Coated onto any type of cellulosic pre-filter material for ventilation solutions
  • Coated onto materials to create new products or incorporated into existing product ranges to create a ‘+’ product

How GC INK Works

GC’s technology is highly effective due to the 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
  • No shedding of GC Ink particles in airflow tests, addressing toxicity concerns
  • Independently tested to have no measurable impact on airflow

Green Technology

Minimal energy used in manufacturing and no additional energy required to use

Use Case

There is an acute focus by government and health institutions globally on good quality air through the improvement of indoor ventilation and in particular, to reduce exposure to airborne pathogens like SARS-CoV-2.

Ventilation in one room may carry infectious viruses into connected rooms through HVAC vents that serve multiple rooms – common in schools, hospitals and office buildings. If a person with COVID-19 were in one room, infectious virus particles could move from the infected room to uninfected ones.

And that’s where virucidal filtration comes in.

GC Ink™ coated pre-filters can be quickly installed in existing HEPA filters and ventilation systems without the need for retro-fitting – making it a fast, affordable and highly effective way of making the air we breathe cleaner and safer.

GC Ink™ – how to use in ventilation solutions

  • As a pre-filter for existing HEPA and air filters
  • No retro-fitting – versatile solution, compatible in existing air ventilation systems
  • No additional maintenance management – becomes a part of the existing filter and recycled as such
  • No reduction in performance of airflow

GC Ink™ FAQs

Questions you may have

  • What is GC Ink™

    GC Ink™ is our patent-pending graphene oxide/silver nanoparticle formulation that forms a virucidal layer on fabrics and surfaces.

  • How does it work?

    GC Ink™ works with a dual action, “trap-and-neutralize” nano-chemistry where graphene oxide and silver nanoparticles work together.

    The negatively-charged surface of the graphene oxide traps water droplets and the protein spikes on coronavirus; the silver nanoparticles neutralize coronavirus by oxidizing the membrane that protects the RNA inside.

    All this happens on the nano-scale – which makes it more effective. If you’d like the detailed scientific version of this, you can look at the Brown University report.

  • Is it effective?

    Yes, tests by Brown University have shown that GC Ink™ in liquid form is 100% effective against Human Coronavirus OC43 and Influenza A H1N1 viruses – in less than one minute.

    Also, independent UK ISO tests on GC Ink™ treated fabric to determine antiviral activity on textiles have been certified to show at least 99% effectiveness against SARS-CoV-2 – tested according to ISO 18184:2019

  • Is it safe?

    Yes, an independent study by the UK Centre for Process Innovation (CPI) confirms no shedding of GC Ink™ particles in airflow tests of GC Ink™ treated filter materials – addressing toxicity concerns. The CPI study used over 20,000 sampling data points to measure particle shedding of GC Ink™ and found none.

    We are preparing for the US Environmental Protection Agency (EPA) approval process, as well as the EU’s Biocidal Products Regulation (BPR) approval process, covering both effectiveness and safety, and we are obtaining International Standards Office (ISO) certifications for product applications.

  • Why did you develop GC Ink™

    We developed the ink in response to the Covid-19 pandemic. Before the pandemic hit, we were working on a joint project with Brown University to develop a graphene oxide formulation to coat on clothing that would protect against mosquito bites – we significantly adapted and extended this formulation to protect against Coronavirus.
