Figure 2. . Biocompatibility of blank polyethylene glycol–poly(lactic-co-glycolic acid) nanoparticles in BeWo cells at various concentrations after 4, 24 and 48 h of exposure, as assessed by the WST-1 colorimetric assay.

Figure 2. 

Triton X-100 was used as a negative control, and blank cell culture medium without nanoparticles was used as the positive control (set to 100% cell viability). The error bars represent the standard deviation (n = 6).

PLGA: Poly(lactic-co-glycolic acid).
