Nanowerk August 20, 2024 Healthcare textiles serve as key reservoirs for pathogen proliferation. Researchers in Canada developed a new class of Smart Fabrics (SF) with integrated “Repel, Kill, and Detect” functionalities, which they achieved through a blend of hierarchically structured microparticles, modified nanoparticles, and an acidity-responsive sensor. It showed good resilience against aerosol and droplet-based pathogen transmission, showed a reduction exceeding 99.90% compared to uncoated fabrics across various drug-resistant bacteria. Experiments involving bodily fluids from healthy and infected individuals revealed a significant reduction of 99.88% and 99.79% in clinical urine and feces samples compared to uncoated fabrics. According to the […]

The ‘invisible’ cellulose coatings that mitigate surface transmission of pathogens
Phys.org May 17, 2023 Researchers in the UK have developed antimicrobial surface film based on sustainable micro fibrillated cellulose. The porosity, and microstructure of the film can be modulated by the formulations and the coating process. They observed a threefold reduction in water contact angles and accelerated water evaporation kinetics on the cellulose film (more than 50% faster than that on a flat glass surface). It exhibited a rapid inactivation effect against SARS-CoV-2 in 5 minutes, following deposition of virus-loaded droplets, and an exceptional ability to reduce contact transfer of liquid, e.g., respiratory droplets, to surfaces such as an artificial […]
