Figure 8. Antibacterial properties of silver nanoparticle-infused cotton fabrics washed for 50 cycles using home laundering and drying machines.(A) Total viable P. aeruginosa and S. aureus bacteria after 24 h. CFU indicates colony-forming units. Percent reductions calculated by eq 2 were labeled. (B) Photographs of the test plates of (left) P. aeruginosa and (right) S. aureus for (top) control and (bottom) silver nanoparticle-infused cotton fabric. The values on the right bottom indicate the dilution of the counted plates.
