Waterbury, Connecticut Patent of the Year – 2024/2025
Kuprion Inc. has been awarded the 2024/2025 Patent of the Year for its breakthrough in biofilm-resistant surface technology. Their invention, detailed in U.S. Patent Application No. 20240156102, titled ‘Biofilm-resistant articles coated with metal nanoparticle agglomerates’, uses coatings of metal nanoparticle agglomerates to inhibit biofilm formation on surfaces exposed to liquids.
Biofilms are persistent microbial layers that can compromise medical devices, water systems, and industrial equipment. Kuprion’s innovation introduces a coating composed of copper and silver nanoparticles, which disrupts biofilm development. These nanoparticles, ranging from 50 to 250 nanometers, cluster into agglomerates measuring 1 to 35 microns. When applied to surfaces, they create a hostile environment for microbial growth, effectively reducing biofilm formation.
The coating is versatile, suitable for medical implants, water filtration systems, and marine equipment. Its composition includes biologically compatible adhesives, ensuring safety for medical applications. The nanoparticle agglomerates can also incorporate additional compounds like nickel oxide and titanium dioxide to enhance antimicrobial properties.
This development offers a proactive approach to preventing biofilm-related issues, reducing the need for chemical cleaners and extending the lifespan of various devices. By integrating this technology, industries can achieve better hygiene standards and operational efficiency.
Kuprion’s advancement in nanoparticle coatings represents a significant step forward in materials science, providing a practical solution to a widespread problem.
