Platinum nanoparticles with photocatalytic binders for swift virus inactivation on textiles and surfaces.

Platinum nanoparticles combined with photocatalytic binders enable rapid virus inactivation on diverse surfaces, achieving 99.97 % reduction of Influenza A and 99.9 % of Feline Calicivirus in 15 s. This eco-efficient approach ensures uniform nanoparticle distribution, minimizing waste and offering sustainable antiviral protection for healthcare and other settings, dramatically outperforming existing solutions that require up to 5 min. We tested against Influenza A and Feline Calicivirus, with potential implications for norovirus due to similar viral structures, pending further validation. The binders' role in ensuring uniform nanoparticle distribution represents a breakthrough in sustainable protection technologies, enabling rapid virus inactivation while minimizing material usage across diverse materials including plastics, metals, ceramics, glass, and composites. In healthcare settings such as ICUs, this green technology significantly reduces waste generation and environmental impact while maintaining optimal protection against both current and emerging viral threats.
