Figure 7. Toxicity evaluation of formulations
XµM[AgNPs-PVP]-18%[P407]. A) Confocal images of hFBs
after incubating with XµM[AgNPs-PVP]-18%[P407] (X = 0, 3.125,
6.25, 12.5, 25, 50, or 100) for 24 hours, followed by LIVE/DEAD staining
assay. Scale bar represents 100 µm. B) The percentage cell
viability obtained by counting the number of cells in the confocal
images (similar to A, n = 4 for each group) using ImageJ. Data
represents mean ± SD.
