Poly-γ-Glutamic Acid Nanoparticles Based Visible Light-Curable Hydrogel for Biomedical Application

Figure 9

Alamar Blue assays for comparison of control and PGA nanogel-treated cells in self-control measurements. Mean fluorescence intensities were normalized to the weight of the nanogels. values are in parentheses. Note: control group was 2D grown SAOS-2 cells without nanogel. Error bars represent the SD of three parallel measurements.
