Effect of silver-coated cotton fibers on cytoxicity to human fibroblasts. Phase image (4X, top), viable cells (green, middle), and dead cells (red, bottom) were shown on silver-coated cotton fibers at day 2 (A) and day 7 (B). Each well of 24 well plates contained six concentrations of silver-coated cotton fibers (teared cotton pellets). Silver-coated cotton pellets were teared and distributed on the surface of each culture well. The fibroblasts were seeded at 2 × 104 cells/cm2 onto the cotton fibers in 24 well plates.
