Drawing inspiration from the remarkable properties of antiviral surfaces, particularly those enriched by copper, our creative endeavors have embraced this noble metal to elavate the allure of our cast bronze creations.

In recent times, heightened awareness has emerged regarding copper’s intrinsic antimicrobial properties. Studies have unveiled its prowess in swiftly neutralizing viruses and bacteria upon contact, a phenomenon affirmed by Bill Keevil, a distinguished figure in environmental healthcare at the University of Southampton. Notably, copper’s efficacy extends beyond mere elimination, as it obliterates pathogens down to their nucleic acids, precluding any chance of mutation or evolution.

Motivated by this revelation, we subjected our BC50 bronze liquid metal—reputed for its high copper content—to rigorous testing under ISO 12702 standards, which gauge antiviral activity on non-porous surfaces. Delightfully, our surface demonstrated a remarkable ability to eliminate 99% of human coronavirus NL63 within a span of 2 hours. To contextualize this achievement, contrast it with the prolonged survival of coronaviruses on surfaces like stainless steel, where viability extends up to four days. This groundbreaking result signifies that our existing bronze works are actively combatting bacteria and viruses in the environments they adorn.

Our existing portfolio of BC50 bronze liquid metal creations stands as a testament to copper’s enduring legacy in combatting infectious agents, with documented health benefits tracing back to ancient civilizations like the Egyptians and Romans. Historical records from the 19th century further affirm copper’s effectiveness in preventing cholera when applied topically. Today, scientific evidence corroborates copper’s efficacy in eradicating various microbes, including but not limited to norovirus, MRSA, virulent strains of E. coli, and coronaviruses.

A compelling case study from Pullman Regional Hospital in Washington State, USA, underscores the transformative impact of antimicrobial copper surfaces. Upon integrating these surfaces into critical touchpoints such as tap levers, door access devices, and IV handles, the hospital witnessed a substantial 78% reduction in hospital-acquired infection rates. This success prompted the adoption of additional copper-infused textiles like blankets, sheets, gowns, and towels, further bolstering their infection control measures.

This exemplary case is just one among many, with numerous studies showcasing a minimum 50% reduction in hospital-acquired infections through the strategic implementation of copper-infused surfaces. Despite these compelling outcomes, the widespread adoption of copper in public spaces, hospitals, and transportation networks remains surprisingly limited.

At Alchemy Surfaces, we recognize the profound potential of copper in safeguarding our well-being, that of our loved ones, and our clients. By incorporating metals with high copper content into our designs, we offer a pragmatic yet elegant solution to enhance environmental hygiene. Rather than a complete overhaul to a copper-dominated palette, our approach allows for a diverse range of color tones, encompassing copper, brass, bronze, gold, and even silver. While we have initially certified our BC50 bronze as an antiviral surface, we remain committed to expanding our palette of protective materials in the near future.

We stand at the dawn of a new era of innovation with copper. If you’re intrigued by our current antiviral portfolio and future endeavors, we invite you to reach out to us through the provided link for further discussion and collaboration.
