Diferent barcodes codification for embryo micro-labeling

The development of in vitro reproduction techniques has presented a great concern about the identification of the embryos. In this work, we report the use of a novel barcode branding based on polysilicon and silicon structures for embryo labeling. Four different barcodes types were fabricated based on standard semiconductor techniques and the labeling potential was tested. The codification method was based on a binary code of 8 bits. The results show that these barcodes, microinjected between the pellucid zone and the cell membrane, represents a usefulness technique for embryo labeling.
