Self-Disinfecting Cotton Fabric Shows Promise in Hospital Trials

New cotton fabric neutralizes harmful microbes using ordinary light, cutting lab-tested microbes by up to 75% in hospital settings.

Researchers at Universitat Politècnica de València (UPV) developed self-disinfecting cotton that neutralizes pathogens when exposed to ordinary white light. In trials across 12 hospital rooms at La Fe University and Polytechnic Hospital in Valencia, the material reduced E. coli within 60 minutes, Enterococcus faecalis within 20 minutes, and Candida albicans significantly within three hours. Under direct light exposure, it cut microorganisms by 75% compared to conventional cotton—25% less under reduced light. The fabric retains antimicrobial effects after 20 washes and uses standard textile processes, making it scalable. Published in ACS Applied Materials & Interfaces (October 18, 2026), the material was tested on bed rails and mattresses for 48 hours.

This approach could help reduce hospital-acquired infections by creating affordable, non-toxic textiles that work without chemicals. The light-activated mechanism means the fabric doesn’t require special equipment or frequent reprocessing. For the commons, it offers a low-cost solution to microbial contamination in shared spaces.

Next, the team must confirm real-world efficacy beyond lab conditions and address light dependency for consistent results. Current trials show promise but haven’t yet reached clinical deployment. The material’s potential to lower infection risks through accessible textiles remains unproven at scale.
