Researchers developed chemiluminescent microfluidic chips with dielectric wetting valves that noninvasively analyze embryo metabolites to predict implantation potential during IVF. The device enables precise, label‑free metabolic profiling at small scales compatible with clinical embryology workflows, improving selection without harming embryos. If validated in larger clinical cohorts, the technology could raise IVF success rates by better selecting embryos with higher implantation likelihood and reduce time to pregnancy. Commercialization will hinge on robustness, regulatory clearance, and integration into assisted-reproduction laboratory procedures.
