One issue which sometimes arises in IVF is risk of mismatching errors or mix-ups. A study on mouse embryos in which embryos were tagged with biofunctionalized polysilicon barcodes to the outer surface of the zona pellucida provides a potentially novel solution to this problem. No adverse effects were observed in terms of tagged embryo development and the tagging process survived embryo cryopreservation.
