Transforming Haemodialysis Safety with a Graphene Light-Activated Antimicrobial Device

Objective

Catheter-related infections remain one of the most serious and costly complications in haemodialysis, affecting nearly 17.5% of catheterised patients each year and causing up to 15% mortality. Despite strict aseptic protocols and use of single-use catheter caps, infection rates continue to increase. Current approaches are inherently reactive, chemical- and antibiotic-dependent, fuelling antimicrobial resistance and generating significant medical waste. The clinical and economic toll is severe, costing European healthcare systems over €1.7 billion every year.
The GOcap®, developed by GOTECH Antimicrobial, introduces a paradigm shift in infection prevention. It is the first reusable, light-activated, graphene-based catheter cap that delivers continuous, antibiotic- and chemical-free antimicrobial action directly inside the catheter hub, the primary site of infection. Upon activation by near-infrared (NIR) light, graphene oxide (GO) generates a photothermal and photodynamic effect that destroys 99% of bacteria and fungi, including multidrug-resistant strains, without affecting patient tissues. The device is self-contained, automated, and reusable for at least six months, reducing consumables, cost, and waste while improving patient safety and sustainability.
SAFE-HD project will advance GOcap® from TRL4 to TRL6 through miniaturisation, design lock, and GLP-compliant validation, supported by ISO 13485-certified partners and clinical private and public dialysis collaborators (e.g. Diaverum, CHUSJ). Regulatory preparation (CE/FDA), quality management implementation, and market-readiness activities will ensure a clear and scalable pathway to market.
SAFE-HD will deliver a high-impact MedTech innovation: a new class of reusable, graphene-based antimicrobial devices that directly advance EU priorities on healthcare resilience and sustainability, driven by GOTECH’s multidisciplinary expertise in biomedical engineering, antimicrobial materials, and business.
