Fig. 4: Microbial resistance and bioaerosol elimination of nanofibrillated CFNs.
From: Nanofibrillated collagen fiber networks for enhanced air purification
A Schematic showing the microbial resistance properties of Nano-CFN. B Zeta potential of different collagen-based samples, with Zr-CFN representing CFN cross-linked by Zr(SO4)2. C Anti-mildew performance of different filters after storage at 25 °C and 98% relative humidity. D Bacterial inactivation efficiency of different filters against S. aureus and E. coli. E S. aureus and F E. coli aerosol capture efficiency of CFN, H13, and Nano-CFN in 50 replicate tests. G Inactivation efficiency of S. aureus and E. coli aerosols over 50 cycles, demonstrating the antibacterial durability of Nano-CFN. Data are presented as mean values ± SD (n = 3); the error bars indicate measurement variations.
