Figure 1. PEG-PLGA nanoparticles present the lowest cytotoxicity in ARPE-19 cells.

Figure 1

Cytotoxicity assessment by MTT assay on ARPE-19 cells treated with PLGA, PCL, and PEG-PLGA NPs at three different concentrations, 25, 100, and 200 μg/mL, at 2, 4 and 6 days (A, B, C). Y-axis in each figure represents the MTT absorbance normalized to the control. PEG-PLGA NPs show the lowest toxicity of the three types of NPs, while PLGA NPs present the highest toxicity through day 6. *p < 0.05.
