  abstract = {Striving for sustainable drug discovery, we have presented a proof-of-concept for studying the effects of pharmaceutical agents transported across the placental barrier on neural cells. The potential effects of pharmaceutical agents on fetus have made concerns about their use and require more studies to address these concerns. A placenta-on-a-chip model was fabricated and tested for transport of naltrexone (NTX) and its primary metabolite 6
